We conduct coding interviews as part of the process.

• Ensure reliability, availability and performance of compute nodes running VMs
• Analyze and debug Linux systems across user space and kernel space, understanding capabilities, limitations and trade-offs at each layer
• Troubleshoot complex production issues involving CPU, memory, NUMA, cgroups and scheduling
• Work hands-on with virtualization and containerization, primarily using QEMU/KVM and Linux-native technologies
• Design and evolve observability as a core capability of the node layer: metrics, logs, traces, alerts, SLIs and SLOs
• Lead incident response, root-cause analysis, and postmortems, driving long-term reliability improvements
• Collaborate closely with platform, kernel/hypervisor, GPU and infrastructure teams to improve system design and operability

• Experience with Kubernetes internals or node-level components
• Hands-on experience with low-level Linux debugging tools (e.g. perf, eBPF, ftrace, strace, kernel crash dumps)

Token Factory is a part of  Nebius Cloud, one of the world’s largest GPU clouds, running tens of thousands of GPUs. We are building an inference platform that makes every kind of foundation model — text, vision, audio, and emerging multimodal architectures — fast, reliable, and effortless to deploy at massive scale. To deliver on that promise, we need an engineer who can make the platform behave flawlessly under extreme load and recover gracefully when the unexpected happens.

In this role you will own the reliability, performance, and observability of the entire inference stack. Your day starts with designing and refining telemetry pipelines — metrics, logs, and traces that turn hundreds of terabytes of signal into clear, actionable insight. From there you might tune Kubernetes autoscalers to squeeze more efficiency out of GPUs, craft Terraform modules that bake resilience into every new cluster, or harden our request-routing and retry logic so even transient failures go unnoticed by users. When incidents do arise, you’ll rely on the automation and runbooks you helped create to detect, isolate, and remediate problems in minutes, then drive the post-mortem culture that prevents recurrence. All of this effort points toward a single goal: scaling the platform smoothly while hitting aggressive cost and reliability targets.

Success in the role calls for deep fluency with Kubernetes, Prometheus, Grafana, Terraform, and the craft of infrastructure-as-code. You script comfortably in Python or Bash, understand the nuances of alert design and SLOs for high-throughput APIs, and have spent enough time in production to know how distributed back-ends fail in the real world. Experience shepherding GPU-heavy workloads — whether with vLLM, Triton, Ray, or another accelerator stack — will serve you well, as will a background in MLOps or model-hosting platforms. Above all, you care about building self-healing systems, thrive on debugging performance from kernel to application layer, and enjoy collaborating with software engineers to turn reliability into a feature users never have to think about.

If the idea of safeguarding the infrastructure that powers tomorrow’s multimodal AI energizes you, we’d love to hear your story.

• Serverless AI has clear product-market fit with measurable activation and retention metrics improving quarter over quarter.
• Multi-node jobs and autoscaling endpoints are shipped and adopted by customers running production workloads.
• Cold start time is reduced from 1-3 minutes to under 60 seconds for common workloads through a combination of product and infrastructure improvements you drove.
• Developer experience (CLI, docs, error messages, onboarding flow) sets the standard that developers expect from a next-generation AI cloud.
• At least 3 product decisions you made are directly attributable to customer conversations or data analysis you conducted.

• Co-own the Serverless AI product roadmap — Jobs, Endpoints, and DevPods — taking primary ownership of specific product areas while collaborating closely with the other PM on shared priorities and cross-cutting decisions.
• Write detailed, technically precise PRDs that engineering teams can execute against. Our PRDs specify CLI syntax, API contracts, state machines, and billing models — not abstract feature descriptions.
• Make build/buy/defer decisions on capabilities like autoscaling, multi-node orchestration, HTTPS termination, secret injection, and health checking based on customer signal and strategic priorities.

• Understand the full workload lifecycle: container image pull → VM provisioning → GPU attachment → workload execution → cleanup — well enough to identify bottlenecks and propose solutions.
• Evaluate technical trade-offs in areas like container cold start optimization (image caching, snapshot restore, warm pools), GPU scheduling and bin-packing, and storage mount performance.
• Work directly with engineers on architecture decisions for distributed training support, endpoint autoscaling policies, and fault tolerance mechanisms.
• Stay current on the fast-moving serverless GPU infrastructure space — new inference frameworks (vLLM, TensorRT-LLM, SGLang), container runtimes, orchestration approaches — and translate trends into product direction.

• Run customer discovery and feedback sessions with ML engineers and platform teams at AI startups and enterprises. Turn qualitative insight into specific product actions.
• Analyze usage data, activation funnels, and churn patterns to identify where users get stuck and what features drive retention.
• Track market dynamics, emerging technologies, and industry trends to inform product strategy and ensure Nebius stays ahead of where the market is heading.
• Define and iterate on pricing, packaging, and tier strategy for Serverless AI.

• Own the technical content strategy: quickstart guides, tutorials, reference architectures, and example workloads that reduce time-to-first-job.
• Partner with marketing on developer-focused campaigns, webinars, and conference presence.
• Work with Solution Architects and Sales to qualify serverless-fit opportunities and support technical evaluations.

• You have built, shipped, and iterated on infrastructure or platform products used by developers or ML engineers. Not consumer apps. Not dashboards. Infrastructure.
• You understand containers at a practical level — Docker, image registries, container runtimes, resource limits, networking. You've debugged why a container won't start, why GPU isn't visible inside it, or why a mount isn't working.
• You have working knowledge of GPU computing for AI/ML: what GPU types exist and when to use them, how training and inference workloads differ in resource requirements, what vLLM / TensorRT-LLM / Triton are and why they matter.
• You can read a CLI reference and know if it's well-designed. You've shaped developer-facing APIs, CLIs, or SDKs.
• You have run real customer discovery — not surveys, but technical conversations with engineers where you learned something that changed your product direction.
• You have 3+ years of product management experience in cloud infrastructure, AI/ML platforms, or developer tools.

• Ability to whiteboard a workload lifecycle (submit → schedule → provision → execute → cleanup) and identify failure modes at each step.
• Understanding of autoscaling trade-offs: scale-to-zero vs. warm pools, scaling metrics (queue depth, latency, utilization), cold start implications.
• Familiarity with inference serving concepts: batching, model loading, quantization, KV-cache management, multi-model serving.
• Understanding of distributed training concepts: data parallelism, model parallelism, communication overhead, checkpointing.
• Ability to reason about pricing models: per-second vs. per-request vs. per-token, and how pricing interacts with product architecture.

• Experience at a serverless or GPU cloud company.
• Hands-on ML engineering background — you've trained models, deployed inference endpoints, or built ML pipelines yourself.
• Experience with Kubernetes for ML workloads (Kubeflow, KServe, Ray Serve) and understanding of why many ML teams want to avoid it.
• Prior experience building a product from early stage to scale in a fast-growing market.
• Background in systems engineering, distributed systems, or site reliability engineering.

• You are more comfortable in a terminal than in a slide deck.
• You form strong opinions based on data and direct customer signal, and you update them when evidence changes.
• You are energized by building at pace — small team, fast-evolving product, big opportunity.
• You care about developer experience at the level of error messages, CLI flag naming, and documentation quality.
• You'd rather ship a smaller thing that works perfectly than a bigger thing that's mediocre.

#LI-KT1

At Wolt, as a part of Doordash, we’re building the industry’s most scalable and reliable delivery platform to support our three-sided marketplace of consumers, merchants, and courier partners. 

What makes our team unique

• Our global Security team aspires to be the world’s most admired security team, with members across EU, UK and North America (operating as Wolt, Deliveroo and Doordash).
• We’re shaping our next generation infrastructure that is hardened from the ground up. This is a rare opportunity - no legacy tech or off-the-shelf product solutions. There is a lot to do around this new development as well as our “classic” platforms of the three companies.
• The greater team is not just information security - we’re more holistic, and also physical security and safety are a part of our global operations.

Day-to-day in this role you’ll:

• Identify and prioritize risk-reducing and engineering-enabling improvements, and then implement and build them, for our infrastructure and cloud security. This may involve the cloud, access controls, the management plane, or just about any other part of infrastructure we have, across any of our platforms. Implementation and building may range from configuring services as infrastructure as code to actual coding of new features.
• Solve security-related questions and implement requests related to our infrastructure security, including reactive fixes related to vulnerabilities or design flaws.
• Guide our engineering teams related to security, privacy and technical compliance.

Over time, your role can evolve depending on your interests and skills. Our company is  a large place and there’s a lot to do!

This position is ideal for someone who would describe themselves as a cloud sysadmin, having an SRE role, or being a DevOps engineer. You are likely to have at least 5 years of full-time experience working in information technology.

As the Security team sometimes needs to address high-priority security issues as well as ensure the availability of the components we have built, this position includes an on-call duty. On-call compensation and terms will be agreed separately in accordance with the local employment law.

Our humble expectations

• Have hands-on experience with AWS, Kubernetes and how modern microservice architectures work. This is a “must” requirement.
• Are quick to form good working relationships with engineers who are building our platforms, as well as their engineering and product management.
• Are quick to learn nuances in a wide variety of additional services that relate to running a low-latency, high-availability infrastructure.
• Are fluent in at least one programming language, even if this comes from a hobby background.
• Have a strong work ethic, are organized and follow things through.
• Can communicate clearly and provide good visibility to issues as they progress.
• Can see through issues that have many aspects and different - often also non-technical and business-related - considerations.
• Are not scared of submitting and reviewing Pull Requests.
• And as Wolt’s company language is English, you’d need to be fluent in both spoken and written English.

This position is open in our Wolt hubs in Berlin, Germany, or Helsinki, Finland, and will be a part of the Global Security Engineering team.

Next steps

The position will be filled as soon as we find the right person, so make sure to apply as soon as you realize you really want to join us!

• We actively encourage healthy, proactive, and diverse debate internally about what we do and how we choose to do it. Teams and individual engineers are trusted (and encouraged) to practise responsible autonomy and critical thinking, and to focus on outcomes, not conformity. At Helsing you will have a say in how we (and you!) work, the opportunity to engage on what does and doesn’t work, and to take ownership of aspects of our culture that you care deeply about. 

What we offer

• A focus on outcomes, not time-tracking

• Competitive compensation and VSOP options

• Relocation support

Join us as a (Senior) Product Manager (all genders) in our Payment team (parental leave cover for 18 months) and help shape the future of autonomous mobility!

At MOIA, we build technology that enables cities and mobility operators to run mobility services safely, efficiently, and at scale. Our mission is to accelerate the shift toward sustainable, shared autonomous mobility - supported by flexible and scalable payment solutions for both end users and B2B partners. 

As a (Senior) Product Manager, you’ll be part of the Payment team, responsible for shaping how money flows through MOIA’s mobility ecosystem - evolving from a pure ridepooling operator to a technology and Autonomous Mobility (AD) focused Mobility-as-a-Service software provider. 

We are a cross-functional team of backend engineers, app developers, quality specialists and an agile coach, working together to build reliable and scalable payment solutions. 

Having successfully delivered and operated payment solutions for millions of rides for our Hamburg services, we are now entering the next phase: Expanding our platform to support MOIA’s MaaS offering and Autonomous Driving services across multiple international markets and across different B2B/B2G partners. This includes addressing new challenges such as multi-tenant payment architectures, partner integrations, regulatory complexity, and new monetization models. 

As a (Senior) Product Manager, you will continue to evolve our payment platform within a B2B / B2B2G context, scaling existing capabilities and adapting them to diverse partner and market requirements. You will treat payments as a product in its own right - balancing user experience, partner needs, and commercial viability. 

This is a key moment to join, bringing your expertise and enthusiasm for payment solutions, and contributing to the continued success of innovative urban mobility solutions. 

What you will do

• Build a deep understanding of the challenges and opportunities of multi-tenant payment systems, enabling cities, partners, and operators to run mobility services for their users.
• Own MOIA’s payment domain end-to-end, defining and executing a roadmap that turns company strategy into a scalable and competitive payment product for the future of an AD mobility provider. 
• Understand and translate the needs of B2B and B2G clients into robust payment solutions by actively engaging with partners - facilitating workshops, aligning on requirements, and guiding them through integrations that enable them to launch and operate MOIA’s white-labelled mobility services. 
• Make trade-offs between standardisation and partner-specific needs in a multi-tenant environment. 
• Prepare and prioritize features as epics and stories for refinement with your team while respecting architectural and technical constraints. 
• Collaborate closely with the Technical Lead and Agile Coach to ensure product quality, delivery reliability, and a healthy team dynamic.
• Create clarity and visibility across domain leadership and partner teams (e.g. Booking and Accounting) on goals, trade-offs, risks, and dependencies.
• Own and manage relationships with external payment providers (e.g. Adyen), balancing partner capabilities, costs, risk, and scalability.
• Leverage AI in day-to-day product work to improve processes, decision-making, and product capabilities, and actively contribute to evolving AI practices within the Product Community.
• Represent the Payment team within the Product Community, sharing learnings from building complex, platform-oriented payment systems and contributing to overall product excellence.

What will help you to fulfill your role 

• Payment Domain knowledge: You have worked within the payment domain and have a track record of building payment solutions at scale – B2B2C payment setup or payment integrations with (public) clients is a big plus! You don’t shy away from building within the constraints of regulations, taxation, invoicing. In short: Your heart is beating for payments – and you share that passion with anyone who’ll listen!  
• Excellence: You bring solid experience in Product Management and are able to balance business, stakeholder, and user needs effectively. You create shared understanding and ensure that priorities are aligned and understood by relevant stakeholders. 
• Visionary: You think big, craft compelling visions for your ideas and understand what makes your products commercially viable. You are excited about bringing business value and can bridge the gap between technical world and business world.  
• Pragmatist: You get things done, make sound decisions and resolve issues effectively. You enjoy getting involved and discussing complex technical challenges - and then you trust the team to take it from there to figure out architecture and implementation.  
• AI-driven mindset: You actively use modern AI methods in your day-to-day work - from discovery and analysis to decision-making and delivery. You are curious about how AI can improve both internal processes and product capabilities, and you contribute to evolving practical AI usage within the Product Community. 
• Excellent Communicator: People enjoy working with you because you communicate well and evoke optimism, even when you’re communicating complex information. You are experienced in adjusting your messaging to different stakeholders and inspire people by translating your in-depth domain expertise into clear and straightforward language. Plus, you are not afraid of asking a lot of questions to refine your understanding.  
• Fluent communication in English is required; German is a plus. 

We welcome applicants from diverse backgrounds — even if you don’t meet every requirement. If you’re excited about the role and MOIA’s mission, we’d love to hear from you!

The Role

As a Senior Platform Engineer at Gigs, you'll work at the foundation of everything we build. You'll design, build, and operate the infrastructure and developer tooling that powers our connectivity and payments platform — enabling product teams to ship faster, more reliably, and at scale.

Our Foundation team owns the systems that every engineer at Gigs depends on: CI/CD pipelines, cloud infrastructure, observability, deployment tooling, and the shared platform services that keep our product running. You'll take ownership of complex infrastructure challenges end-to-end and drive them to production with a high bar for reliability and developer experience.

This is a role for someone who cares deeply about the craft of platform engineering — who gets energy from making other engineers more productive, who thinks in systems, and who isn't satisfied until the solution is both robust and elegant. You'll be joining a small, high-impact team where your work will directly shape how Gigs scales over the next few years.

What You Will Do

• Own and improve Gigs' cloud infrastructure, ensuring our platform is reliable, scalable, and cost-efficient as we grow.
• Design and build internal developer tooling and platform services that accelerate how product teams ship — from CI/CD pipelines to deployment workflows to local development environments.
• Drive improvements to our observability stack, making it easy for every engineer to understand system behavior, debug issues, and respond to incidents with confidence.
• Take complex infrastructure problems end-to-end: scoping, designing, implementing, and operating solutions in production.
• Collaborate closely with product engineering teams to understand their pain points and build platform capabilities that unblock them.
• Contribute to our infrastructure-as-code practices, ensuring our cloud environments are reproducible, auditable, and version-controlled.
• Participate in on-call rotations, incident response, and post-mortems — and use what you learn to make our systems more resilient.
• Raise the bar for platform engineering quality through code reviews, documentation, and advocating for best practices across the team.

What We Are Looking For

• You have 5+ years of professional software engineering experience, with meaningful time spent on infrastructure, platform, or DevOps/SRE work in a production environment.
• You have experience designing and building a platform layers e.g. centralised authentication, observability, routing logic, or API versioning which other product teams integrate against or build on top of.
• You have hands-on experience with cloud platforms (GCP preferred) and infrastructure-as-code tools like Terraform. You understand networking, compute, and storage at a level that lets you make good trade-offs.
• You have experience building and maintaining CI/CD pipelines and deployment systems. You care about developer experience and know that a great platform is one that engineers actually want to use.
• You think in systems. You can reason about distributed architectures, understand failure modes, and design for reliability and observability from the start.
• You enjoy building products from the infrastructure up. You care about finding the right solution to internal customer needs, and you're comfortable taking ownership and delivering.
• You communicate clearly and collaborate well. You can explain infrastructure decisions to product engineers, write useful documentation, and contribute to technical discussions with confidence.
• You care about more than just engineering — you want to see the business impact of everything you do, and you know how to make pragmatic speed/quality trade-offs.
• You have a growth mindset when it comes to tooling and practices. You stay curious about how the industry is evolving — including AI-assisted development — and you're thoughtful about adopting what makes you and your team more effective.

Bonus Points If

• You have experience with our stack: GCP (cloud run), Docker, Terraform, Ruby on Rails, Go, PostgreSQL, Kafka, PubSub.
• You have worked in fintech, payments, telecom, or other regulated industries where reliability and compliance matter.
• You have experience building developer-facing platforms or internal tooling at a high-growth startup (Series B–D).
• You have contributed to open-source infrastructure tooling or have a track record of improving developer productivity at scale.
• You use AI tooling as part of your engineering workflow and have developed a practical sense for where it adds value and where it doesn't — for example, using it for infrastructure scaffolding, debugging, exploring unfamiliar APIs, or drafting documentation, while knowing when to rely on your own judgment.

THE BEST WORK OF YOUR CAREER

Trade Republic is the largest savings platform in Europe - we operate in 17 countries, serving +4 million customers who trusted us with over 35B in assets. But we’re striving for more.

We have a bold mission to empower everyone to build wealth with easy, safe, and free access to financial systems. You will have the opportunity to grow your career by collaborating with a team of outstanding talents and state of the art technology to build a lasting, positive future for millions.

ABOUT PLATFORM ENGINEERING

Platform Engineering is the backbone of Trade Republic's engineering velocity. Our mission is to build scalable platforms for a Europe-scale bank — serving internal engineers, and building in-house control planes for managing the bank's infrastructure. We’re a ~50-person Platform team focused on one thing: enabling product engineers to move fast and operate autonomously by default.

We build self-service platforms, golden paths, and opinionated tooling so that over 400 engineers can ship with confidence. From Kubernetes fleet management and CI/CD to an internal Developer Hub built on Backstage, our work underpins every trade, savings plan, and card payment that flows through the platform.

THE CLOUD PLATFORM JOURNEY

Trade Republic's cloud infrastructure spans multiple AWS accounts across development, staging, and production environments — supporting regulated financial services across 18 European markets. Today, much of this is managed through Terraform. We're making a deliberate strategic shift: moving from declarative infrastructure-as-code toward programmable control planes — Go-based systems that use tools like Pulumi and Crossplane to continuously govern, reconcile, and automate our cloud foundations.

This isn't about running Terraform plans faster. It's about building software that manages a bank's cloud infrastructure as a product — encoding compliance, security, and cost best practices into systems that enforce the right thing by default. The patterns are already proven: our Kubernetes fleet management uses Crossplane with Sveltos, FluxCD, and ClusterAPI, and our Temporal-backed control planes already manage database and messaging operations using Pulumi. Now we need to bring this same approach to AWS account management, IAM governance, organisational structure, and networking — IAM policies, account structures, network topologies, and organisational guardrails, all governed through code that reasons about intent, detects drift, and converges autonomously.

We've gone from manually provisioned infrastructure to a platform where compute autoscales across clusters, fleet management orchestrates add-on lifecycles across environments, and infrastructure provisioning runs as self-healing workflows with cross-account automation — no human in the loop. The next frontier is bringing this same level of automation to the cloud foundations layer itself.

We also own Trade Republic's partner connectivity — the network fabric that connects us to exchanges, payment providers, and banking partners through site-to-site VPNs, AWS Direct Connect, VPC peering, transit gateways, and more. These connections are mission-critical and must be production-ready ahead of every company release.

WHAT YOU'LL BE DOING

• Build cloud control planes: Design and implement Go-based systems that programmatically manage AWS infrastructure — accounts, IAM, networking, and organisational policies — replacing manual Terraform workflows with self-healing, intent-driven automation.
• Encode governance as software: Turn compliance, security, and cost requirements into programmable guardrails that are enforced continuously, not checked after the fact — meeting the same bar of reliability and self-service that our engineers already expect from the rest of the platform.
• Own partner connectivity: Build and operate the network infrastructure that connects Trade Republic to exchanges, payment providers, and banking partners — ensuring these connections are resilient, secure, and ready ahead of every release.
• Own the platform end to end: Participate in the on-call rotation for cloud infrastructure, ensuring full end-to-end ownership of the systems you build and operate.
• Own the direction and drive it forward: Define the long-term cloud platform strategy, drive cross-team initiatives from kickoff to delivery, and align cloud infrastructure decisions with broader engineering, compliance, and cost goals.

WHAT YOU'LL SHIP IN THE FIRST 6 MONTHS

• Build control planes that integrate into Kubernetes fleet management — solving cross-account and cross-region connectivity, role management at scale, and levelling up our organisational structure.
• Continue refining cloud governance standards for IAM, account structure, and cost controls — pushing further toward enforcement through code, not process.
• Drive reliability improvements across partner connectivity — reducing manual effort, lead time, and failure modes for provisioning and managing network connections.

WHAT WE'RE LOOKING FOR

• 5+ years of experience in cloud platform engineering, infrastructure engineering, or a related SRE/systems discipline.
• We are hiring from senior to staff level, so whether you have a strong foundation and are ready for more ownership or you have been leading cloud platform strategy for large-scale systems for many years, we would love to hear from you.
• Strong programming skills in Go, with experience building infrastructure automation as software rather than scripts.
• Deep expertise with AWS — IAM, Organizations, networking (VPC, Transit Gateway, Direct Connect, VPN), and multi-account architectures.
• Experience with infrastructure-as-code tools (Terraform, Pulumi, Crossplane, or equivalent) and a clear understanding of when declarative configuration ends and programmable control planes begin.
• A track record of building systems that enforce compliance, security, and cost governance through automation rather than manual review.
• Experience with Kubernetes and cloud-native architectures in production.
• Ability to drive cross-team technical initiatives end-to-end, from ambiguous problem to shipped solution.
• Ability to contribute to architectural decisions and clearly communicate trade-offs to both engineers and leadership.
• The ability to work in a flexible hybrid setup, with 2-3 days a week in the office.

IONOS Cloud is a machine with many moving parts. Dozens of software components work together to provide the services offered. We are establishing a new team to better support and monitor this machine and improve the existing tooling and level of automation. We primarily rely on Kubernetes operators and cloud-native software such as ArgoCD, OpenBAO, Prometheus, etc. Our own in-house developments are also common.

As with a spaceship or aeroplane, we don't just need mechanics with oil cans, but also a team of engineers who continuously improve the overall process, build new tools where necessary and provide the other teams with everything they need to do a good job make (such as customer support, product developers or operations teams).

The underlying idea and goal is to end up with a self-healing "desired state" system that is controlled via GitOps and offers all products and components uniform processes and a reusable tool landscape.

We will help other teams with this transition if necessary - including possible containerization, immutable infrastructure, idempotent interfaces, etc. The Platform Flight Engineering team will include software development, operations and infrastructure engineering. Our flight engineers will also regularly "fly" with other teams in order to better understand the engine room there.

Tasks

• Developing tools for the entire lifecycle of cloud products and platforms.
• Development of Kubernetes operators for the autonomous operation of software components.
• Developing APIs, tools and components to support other teams in their work.
• Support of product platforms including on-call (of course with the aim of the software doing all the work).
• Code reviews.
• Promoting junior and advanced members of the team.
• Participation in interviews during hiring.
• Accompanying other teams in their work.

Qualifications

• Sound knowledge of software development, preferably with GoLang.
• In-depth knowledge of cloud environments and Kubernetes.
• Agile mindset, experience with modern software development methods.
• Experience in operating IT platforms based on Linux and Kubernetes.
• "Show must go on" mentality.
