We’re looking for passionate and product-minded Backend Engineers to join our Discovery team - the group behind some of the most visible and impactful parts of Wolt’s consumer app. You’ll work on features that help millions of users discover their next favorite restaurant, grocery store, or product- from the homepage and category views to new vertical experiences like groceries, electronics, pet food, and health & beauty.

This is more than just a backend engineering role. We’re looking for someone who combines strong technical skills with curiosity, ownership, and a deep interest in creating meaningful user experiences at scale.

AI-First Engineering in Discovery 

We're building teams at the forefront of agentic coding. This goes beyond autocomplete or occasional prompting. We’re looking for engineers who:

• Design workflows where AI agents handle entire task loops, from spec to PR.
• Think in terms of orchestration: what does a human review, what does the agent own?
• Build internal tooling and abstractions that make AI-assisted development faster and more reliable for the whole team.
• Stay curious and ahead of the curve - trying new models, agents, and tools as they emerge, and forming strong opinions about what's genuinely useful vs. hype.

If you find yourself naturally asking "can an agent do this?" before reaching for the keyboard, you'll fit right in.

What you’ll do:

• Design, build, and operate high-performance backend services - primarily in Kotlin and Go (experience with Python is a plus) -  powering discovery surfaces, front pages, and category experiences across Wolt’s new and existing verticals.
• Own your services end-to-end: from requirements, design, and delivery to testing, CI/CD, deployment, monitoring, and on-call.
• Translate product and user needs into scalable, low-latency solutions and run experiments (A/B tests, feature flags) to continuously improve performance and impact.
• Collaborate closely with Product Leads, Frontend, Data, and Machine Learning teams to build features like search, ranking, personalization, and data-pipeline integrations.
• Drive reliability, observability, and efficiency - through automated testing, logging, tracing, alerting, incident response, and post-mortems.
• Continuously improve technical quality by reducing tech debt, proposing architectural improvements, and measuring their outcomes.

Why this role?

Join our Discovery team and shape how users experience Wolt from the moment they open the app.

• An AI-first team by design: We don't use AI as a productivity add-on - we treat agentic coding as a core engineering discipline. We expect our engineers to build with AI agents, to challenge what's possible when the human-in-the-loop is a multiplier rather than a bottleneck, and to push the boundaries of what a small, focused team can ship.
• Real ownership, real impact: Discovery is one of the most critical parts of the product. You’ll own features end-to-end and see your work directly influence user behavior at scale.
• Cross-functional collaboration: You’ll work closely with product managers, designers (including motion), backend engineers, and data teams to build seamless user experiences.
• A small team with high leverage: We operate as a tight, cross-functional team where engineers have a strong voice, move fast, and take responsibility for what they ship.

What we’re looking for

• Solid engineering fundamentals: At least 1-2 years of experience building production backend services 
• Genuine enthusiasm for AI-first development: You use AI tools daily and have formed real opinions about how to get the most out of them.
• End-to-end ownership mindset: You take responsibility beyond implementation, from breaking down problems into technical tasks to ensuring features are tested, stable, and successfully shipped
• Ability to work independently and drive projects: You’re comfortable owning work end-to-end with minimal guidance, collaborating with designers to clarify requirements, creating tasks, and moving initiatives forward
• Product and execution thinking: You operate well in ambiguous environments and contribute not just to implementation, but to shaping what gets built and how
• Experience operating in production environments: You’ve debugged real issues in live backend services and understand what it takes to maintain reliability at scale
• Collaboration and communication: You communicate clearly and work effectively across teams, including in multi-team development environments

🌍 Where You’ll Work

You will be based in Helsinki, and be a part of a distributed, cross-functional team with engineers in Berlin and Helsinki. We operate in a remote-friendly environment designed to encourage collaboration and innovation.

Next steps

These positions will be filled as soon as we find the right persons, so make sure to apply as soon as you realize you really, really want to join us!

At Wolt, world-class customer service isn’t an afterthought, it’s at the heart of everything we do 💙 We’ve built our reputation on delivering fast, thoughtful, and high-quality support, and we’ve done that by investing deeply in our own technology. Rather than just reacting to problems, we aim to solve them before our customers and partners even notice. Behind the scenes, that means building systems that scale globally, handle real-world complexity, and empower support teams to do their very best work. 

This is where the Multilingual Intelligence & Resolution Automation (MIRA) team comes in. The team is on a mission to make customer support truly borderless. We’re building intelligent, AI-powered systems used across Wolt, DoorDash, and Deliveroo, including a real-time translation engine that supports seamless conversations across 20+ languages. Processing hundreds of requests per minute and powered by modern cloud infrastructure and state-of-the-art LLMs, this system enables borderless support and helps create experiences that feel natural, human, and native, no matter where you are in the world. And we’re only just getting started. 🚀

What you’ll be doing

• Design, build, and operate scalable backend services powering real-time, customer-facing systems
• Develop and evolve AI-powered translation capabilities using LLMs in production
• Help build the tooling and infrastructure needed to evaluate models across quality, latency, and cost
• Collaborate closely with product, applied science, frontend, and platform teams to turn complex support problems into robust user-facing systems
• Take ownership of technical decisions and help shape the architecture and future direction of the system
• Improve the performance, reliability, and operational readiness of services handling real production traffic
• Continuously explore better ways of working, including leveraging AI tools to improve development workflows

Our humble expectations

• 👉 You have solid experience designing, building, and integrating quality software (microservices) at scale within a complex domain.
• 👉 You have strong backend development skills in Python or Go (interest in other tech is highly appreciated)
• 👉 You actively leverage modern AI tools (such as GitHub Copilot, Claude, ChatGPT or similar) to enhance your productivity, code quality, and day-to-day development workflow.
• 👉 You have strong technical leadership skills.
• 👉 You have experience with cloud platforms (AWS or similar), container orchestration (Kubernetes, Docker), observability tools (such as DataDog), and database technologies (SQL and NoSQL).
• 👉 Your stakeholder management skills are excellent.
• 👉 You're a pragmatic problem-solver with a growth mindset, eager to step outside your comfort zone and continuously learn.
• 👉 You're comfortable working with real-world data and its nuances.

What we offer

• A chance to build something that truly matters, technology that enables people to connect and solve problems across languages and borders
• The opportunity to work with AI and LLMs in real, high-impact production use cases
• Flexibility to work from Helsinki or Tallinn (hybrid), or remotely within Finland or Estonia
• Being part of a global engineering organization of 2000+ people, we aim to build none other than the best-in-the-world engineering team here.
• You’ll get to work in a company culture where we take ownership beyond the obvious, do common things uncommonly well, we think big but stay humble, do right by people, we treat others kindly and justly, recognise that if we don’t learn, we won’t stay still but fall behind, and keep in mind that Luke was Yoda’s greatest achievement.

🙌 Join us for an exciting journey of creating technology that brings joy, simplicity, and earnings to the neighbourhoods of the world!

• Improve developer experience around CI/CD collaboration with CloudDX 
• Identify and eliminate friction across the developer journey
• Build and evolve self-service tooling and internal platforms (DX/IDP)
• Establish and improve developer productivity metrics and engineering insights (e.g., DORA, DX)
• Enable engineering scalability through better tooling, shared libraries, standards, and automation
• Partner across teams to improve developer experience without blocking autonomy

Requirements: 

• Strong experience in Developer Experience, Platform Engineering, or Internal Tooling
• Proven experience building, rolling out, and operating internal developer platforms (IDP)
• Track record of improving developer workflows and productivity at scale
• Hands-on experience with CI/CD, improving reliability, speed, and predictability
• Experience defining and using developer productivity metrics (e.g., DORA, DX insights)
• Ability to identify systemic friction and solve it with pragmatic, scalable solutions
• Experience building self-service platforms, tooling, and paved paths
• Hands-on experience with, or strong drive to adopt, AI-enabled workflows across the SDLC  
• Passion for using AI to improve engineering velocity, quality, and developer experience
• Strong collaboration skills and ability to influence across teams

Nice to have: 

• Experience with progressive delivery
• Familiarity with cloud-native architectures and Kubernetes-based platforms
• Experience with test platforms / QA automation and improving feedback loops
• Familiarity with modern frontend architectures and microfrontend delivery models
• EST or UK timezone for closer overlap with direct team members

#LI-HYBRID

At Aiven, our vision is to help developers and builders bring their ideas to life with speed and simplicity by providing a data platform that makes open-source infrastructure easily accessible to everyone. We are now embarking on one of our most ambitious strategic bets to ensure open source thrives on European infrastructure. 

The Role

We are looking for a Technical Lead, Cloud to own the technical execution of our new cloud product. This is a small, high-autonomy team with minimal hierarchy. You are the person who translates vision into architecture, infrastructure and shipped product. You will work directly alongside Aiven's VP Strategy, who owns the strategic direction and business outcomes. Together, you form the leadership pair that makes this thing real.

Key Responsibilities

Technical Architecture & Decision-Making

• Own the end-to-end technical architecture for a new cloud product built from the ground up
• Make the critical build, buy and partner decisions across every layer of the stack, aligning trade-offs with VP Strategy for bets that carry strategic or financial weight
• Design for the future from day one: the architecture must support a bold long-term vision that you are expected to shape and contribute to

Execution & Delivery

• Build a high-performance, no-ego team of exceptional engineers and product builders
• Lead the engineering team (backend, frontend, design, architecture) with a relentless bias for shipping while contributing code yourself
• Own the roadmap and delivery milestones

• Work with existing Aiven teams to ensure no misalignment emerges over shared architecture

Infrastructure & Operations

• Build abstraction layers that deliver a first-class cloud experience to developers and agents, regardless of the underlying infrastructure
• Ensure the platform meets rigorous security, compliance and certification requirements from day one
• Plan for infrastructure evolution as the product scales

Cross-functional Partnership

• Partner with go-to-market, policy and design leads to ensure the product narrative is technically credible and market-ready
• Engage directly with early design-partner customers to validate requirements and iterate on the MVP

What We're Looking For:

You are a principal-level engineer with the ability to operate in an early product environment like a founder. You have built and shipped complex infrastructure products like cloud platforms, managed database services or developer tooling. You know what it takes to go from a blank canvas to paying customers in a short timeline.

You have deep expertise in distributed systems, cloud infrastructure and open-source technologies. You have excellent taste and conviction on how modern cloud infrastructure should be built, and the technical seniority to turn that into simple narratives. Experience with bare metal orchestration, storage systems or European infrastructure providers is a strong plus.

You thrive in ambiguity and move fast without waiting for permission. You are a high-energy individual with proven evidence of high-agency problem solving.

Amazing! What’s next:

If you think Aiven is the place for you and that our Values align with yours, send us your resume and we’ll get in touch!

Global Benefits:
