• Support internal and external audits by providing technical evidence and ensuring our access protocols meet strict regulatory standards; proactively identify gaps in our current access landscape and drive initiatives to remediate them.
• Create monitors and alerts for access patterns, diagnosing and resolving issues related to authentication and authorization services.

What you need to be successful:

Background and skills:

• Production expertise in Amazon Web Services (AWS), specifically with IAM, Organizations, and Multi-account security.
• Hands-on experience with Access Management tools, preferably Teleport, or similar PAM/JIT solutions.
• Strong experience with Terraform for managing cloud resources and security policies.
• Solid understanding of Linux systems and networking fundamentals (OIDC, SAML, SSH, TLS, TCP/IP).
• Experience programming in Go and/or Python to automate security workflows.
• Familiarity with compliance frameworks and a proven ability to translate audit requirements into technical solutions.
• Experience with container orchestration (Docker, Kubernetes) from an access and RBAC perspective.
• A "Security-first" mindset with a proactive approach to solving complex permission issues.
• Good communication skills and the ability to work autonomously within a fast-paced environment.

Traits:

• Independently lead tech projects
• Lead and promote technical discussions with engineering audiences
• Mentoring & support of Junior & Mid-level engineers
• Review, assessment & improvement of the current team tool landscape

• Deepest understanding of everything built by the team
• Leading specialist activities, drive tech projects independently
• Bring architectural & technical debt issues into the backlog
• You see the delivery of your team in a broad, domain-wide context
• Building bridges to other areas and be the glue in your own team
• Take full responsibility for your work and projects you participate
• Mature & solution-oriented tech counterpart in any discussion

What’s in it for you:

• Accelerate your career growth by joining one of Europe’s most talked about disruptors.
• Employee benefits that range from a competitive personal development budget, work from home budget, discounts to fitness & wellness memberships, language apps and public transportation.

Who we are

The role

Software only matters when it is actively being used and making a difference. As a Deployed AI Engineer, you will be at the heart of this - taking state-of-the-art software and integrating it into complex systems. You will be defining and executing against the end-to-end outcome and all steps on the way to delivering novel capabilities in some of the most challenging environments around.

For example: you collaborate directly with customer avionics engineers to understand the data structures and APIs used in aircraft mission control systems. Instead of being scared, you embrace the complexity of unfamiliar databases, APIs, or network protocols; you dig into the specification and use your creativity and ingenuity to implement adapters for integrating them with Helsing’s cloud infrastructure. By working closely with our partners and customers (both metaphorically and quite literally), you continuously evolve, improve, and operate Helsing software. You own the outcome end-to-end.

The day-to-day

In close collaboration with our product teams, you will discover and formalise customer requirements, identify bugs, and ship the latest features directly to our users. Technology demonstrations are our chance to shine - you will coordinate between customers, partners, and Helsing engineers to showcase Helsing’s software and AI capabilities in simulations or with real systems.

You should apply if you

• Have a degree in computer science, software engineering, electrical engineering, or other relevant fields.

• Have a broad understanding and creative use of computer systems; this is the Swiss army knife in Helsing’s toolbox of world-class talent.

• Prefer asking questions over stipulating answers.

• Love figuring things out, digging deeper and deeper into unfamiliar systems until it finally clicks, and you understand how they work.

• Are not afraid of legacy systems and would rather make them work than give up and try to rewrite it all.

• Are comfortable with scripting languages such as Bash or Python and have experience with software engineering in C++, Java, Rust, or similar.

• Can navigate and configure Linux systems and have an understanding of network stacks and database systems.

• If applying for Germany- it is a requirement that you are able to speak business level or fluent German

Note: We operate at an intersection where women, as well as other minority groups, are systematically under-represented. We encourage you to apply even if you don’t meet all the listed qualifications; ability and impact cannot be summarised in a few bullet points.

Nice to have

• Experience with Rust and Python.

• Experience with container-based, cloud-native and edge application architectures.

• Experience with maintaining and operating production systems using Prometheus, Grafana, ELK, or similar.

• Experience with SQL, NoSQL, and streaming database systems.

• Experience with production ML systems.

• Bonus points: you have professional experience working in a defence context.

Join Helsing and work with world-leading experts in their fields 

• Helsing’s work is important. You’ll be directly contributing to the protection of democratic countries while balancing both ethical and geopolitical concerns. 

• The work is unique. We operate in a domain that has highly unusual technical requirements and constraints, and where robustness, safety, and ethical considerations are vital. You will face unique Engineering and AI challenges that make a meaningful impact in the world. 

• Our work frequently takes us right up to the state of the art in technical innovation, be it reinforcement learning, distributed systems, generative AI, or deployment infrastructure. The defence industry is entering the most exciting phase of the technological development curve. Advances in our field of world are not incremental: Helsing is part of, and often leading, historic leaps forward. 

• In our domain, success is a matter of order-of-magnitude improvements and novel capabilities. This means we take bets, aim high, and focus on big opportunities. Despite being a relatively young company, Helsing has already been selected for multiple significant government contracts.  

• 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

• Social and education allowances

• Regular company events and all-hands to bring together employees as one team across Europe

• A hands-on onboarding program (affectionately labelled “Infraduction”), in which you will be building tooling and applications to be used across the company. This is your opportunity to learn our tech stack, explore the company, and learn how we get things done - all whilst working with other engineering teams from day one 

Helsing is an equal opportunities employer. We are committed to equal employment opportunity regardless of race, religion, sexual orientation, age, marital status, disability or gender identity. Please do not submit personal data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs, trade union membership, data concerning your health, or data concerning your sexual orientation.

We’re a global team of over 400 people, working together to push the boundaries of open-source technology and multi-cloud solutions. Our vision is to help developers, builders, and creators bring their ideas to life with speed and simplicity, by providing a cloud data platform that makes open-source databases, search, streaming, and application infrastructure easily accessible to everyone. 

The Role

We're looking for a Backend Engineer to join our small, focused ClickHouse team. You'll work on the systems that power our managed ClickHouse service – building, scaling, and operating infrastructure that thousands of customers depend on daily.

You'll write Python that orchestrates database lifecycle operations, dig into Linux internals when things get interesting, and ship features through a well-established CI/CD pipeline. You'll work in a modern async-first Python codebase alongside engineers who care about code quality, type safety, and automation.

If you have experience with ClickHouse internals or C++ – even better. But what matters most is strong backend fundamentals and a genuine interest in databases and distributed systems.

What You'll Do

• Design, build, and maintain backend services in Python (FastAPI, asyncio, psycopg2) that manage the ClickHouse service lifecycle
• Work with CI/CD pipelines (Buildkite, GitHub Actions) to ship code reliably and often
• Investigate and resolve production issues across the stack – from Python application code down to Linux system behavior
• Contribute to technical planning within a small team where your input directly shapes the roadmap
• Write well-tested, type-checked code and participate in thorough code reviews
• Use AI coding tools as part of your daily workflow to accelerate development

What We're Looking For

Must have:

• Solid Python development skills -- you write clean, production-grade Python and understand async patterns (asyncio, aiohttp)
• Strong understanding of databases -- you know how relational and analytical databases work under the hood, not just how to query them
• Deep Linux knowledge (Fedora preferred) -- comfortable with systemd, process management, filesystem internals, and debugging at the OS level
• CI/CD experience -- you've built and maintained delivery pipelines, not just used them
• Familiarity with automated testing -- unit, integration, and system tests are part of how you work
• Experience with AI coding tools -- you actively use AI-assisted development in your workflow and understand how to get the most out of it
• Distributed systems awareness -- you understand the challenges of running services across multiple nodes and regions
• Fluent English -- written and verbal

Nice to have:

• ClickHouse experience -- operational knowledge, query optimization, or contributions to the project
• C++ or C -- ability to read and contribute to database engine code
• Cloud infrastructure experience (AWS, GCP, Azure) with Terraform or similar IaC tools
• PostgreSQL operational experience
• Software and network security knowledge

Why This Role

• Small team, big impact. You're not a cog -- you'll shape the technical direction of a product used at scale.
• Real engineering problems. Database orchestration, distributed systems, performance at scale -- not CRUD apps.
• Modern tooling. Strict type checking, automated formatting, security scanning, and AI-assisted development are the norm, not aspirations.
• Berlin-based, hybrid. The team is in the office 3 times per week.

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:

IONOS Cloud ist eine Maschine mit vielen beweglichen Teilen. Dutzende Software-Komponenten spielen zusammen, um die angebotenen Dienste zu erbringen. Wir gründen ein neues Team, um diese Maschine besser zu betreuen, zu überwachen und das vorhandene Tooling und den Automatisierungsgrad zu verbessern. Dabei setzen wir vor allem auf Kubernetes Operatoren und cloud-native Software wie ArgoCD, OpenBAO, Prometheus, usw. Eigene in-house Entwicklungen sind ebenfalls üblich.

Wie bei einem Raumschiff oder Flugzeug brauchen wir aber nicht nur Mechaniker mit Ölkannen, sondern auch ein Team aus Ingenieuren, die den Gesamtprozess kontinuierlich verbessern, neue Tools bauen wo es nötig ist, und den anderen Teams alles bereitstellen was sie brauchen, um gute Arbeit zu machen (wie zum Beispiel dem Customer Support, Produkt-Entwicklern oder den Operations Teams).

Zu Grunde liegt der Gedanke und das Ziel bei einem selbst-heilenden "desired state"-System zu landen, das per GitOps gesteuert wird und allen Produkten und Komponenten einheitliche Prozesse und eine wiederverwendbare Tool-Landschaft bietet.

Wir helfen anderen Teams, sofern nötig, bei dieser Umstellung - inklusive eventueller Containerisierung, immutable infrastructure, idempotenter Schnittstellen, usw. Im Platform Flight Engineering Team wird man sowohl Softwareentwicklung, Betrieb als auch Infrastruktur-Engineering finden. Unsere Flight Engineers werden außerdem in anderen Teams regelmäßig "mitfliegen", um den dort jeweils vorhandenen Maschinenraum besser zu verstehen.

Für dieses Team suchen wir Verstärkung. Am besten passt Du, wenn Du IT-Plattform-Betrieb beherrschst, aber grundsätzlich anstrebst, robuste Software-Agenten zu bauen, die den Betrieb allein übernehmen können.

Aufgabenbereich

• Entwicklung von Tools für den gesamten Lifecycle von Cloud-Produkten und -Plattformen.
• Entwicklung von Kubernetes-Operatoren für den autonomen Betrieb von Software-Komponenten.
• Entwicklung von APIs, Tools und Komponenten, um andere Teams bei ihrer Arbeit zu unterstützen.

• Code Reviews.
• Förderung von Junior- und Advanced-Mitgliedern des Teams.
• Teilnahme an Interviews beim Hiring.
• Begleitung anderer Teams bei ihrer Arbeit.

Qualifikationen

• Fundierte Kenntnisse in der Softwareentwicklung, bevorzugt mit GoLang.
• Fundierte Kenntnisse von Cloud-Umgebungen und Kubernetes.
• Agiles Mindset, Erfahrung mit modernen Software-Entwicklungs-Methoden.
• Erfahrung im Betrieb von IT-Plattformen auf Linux- und Kubernetes-Basis.
• "Show must go on"-Mentalität.
