AI has dramatically expanded who can build software inside Aiven. People across Finance, People, GTM and Marketing now turn operational problems into working applications much faster than before, and Product Development is starting to build too. Our engineering foundations need to catch up with that new way of working.

You'll own the engineering system for Aiven's internal applications: one foundation that makes building at this scale safe, maintainable and efficient, so applications are easy to maintain, merge and split as the business changes.

You'll prove it on real products. You'll directly own our hiring platform and the gateway that gives applications controlled access to our business systems, and use them to find what the shared layer gets wrong before everyone else depends on it. Then you'll help teams across the company move onto it.

You'll build on Aiven Runtime, our own product, as its demanding internal customer. What you learn running real applications on it goes back to the product teams.

As a Staff engineer, your impact is mostly outside your own team, and your leverage comes through influence rather than authority.

You'll join a small team responsible for the data, systems and internal software behind how Aiven operates, based at our Helsinki HQ. We work together in the office three days a week.

Within two months, you've got the first applications running in production on Aiven Runtime. Within six months, you've shipped the improvements our hiring platform and gateway need most and built what you learned into the shared layer, most of our actively developed applications run on the shared layer, and people across the business ship on it without waiting for you. Within a year, it's the default for everything new we build.

What You'll Own

• Build on our existing engineering foundations. Evolve our shared infrastructure into a supported way to build, deploy and operate internal applications and agents, designed so AI coding agents can follow it as reliably as engineers. Identify what's missing, improve what already works and build reusable components and tooling where they genuinely reduce duplicated work. Make deliberate decisions about which capabilities should be shared, which existing tools are sufficient and where teams need flexibility.
• Own and develop central applications. Own our hiring platform and shared credential gateway, and drive their next improvements. The hiring platform uses TypeScript, React, Fastify and Aiven for PostgreSQL; parts of our wider application estate use Python. You'll work across application code, infrastructure and production operations, and evolve these systems as business needs change.
• Set the technical direction for internal applications. Establish pragmatic engineering standards and architectural patterns. Make decisions about authentication, integrations, deployment and operational concerns, balancing consistency with the freedom teams need to solve different problems. Review designs across Aiven, set the technical standards for this layer, and resolve conflicting technical approaches.
• Make software safe and reliable to operate. Own the release paths, migrations, failure handling and operational controls for the systems you maintain. Establish reusable approaches to security, access control and unattended automation, including what agents and automated workflows may do without human approval. Enforce important boundaries in code rather than relying on instructions alone.
• Enable others to build independently. Work with people across Finance, People, Sales and company operations, including people who aren't professional software engineers. Help them build and operate their own applications, and raise how well they build, including how they use AI. Improve the development experience, remove recurring technical bottlenecks and establish patterns others can use without needing you in the room. Business functions remain responsible for their applications' purpose and adoption; you're accountable for how fast, safe and efficient it is to build and run them.

• You've owned meaningful production software end to end, including what happens when it breaks.
• You have strong software engineering depth and are comfortable owning the infrastructure and production environment underneath what you build.
• You've influenced engineering decisions outside your immediate team through design review, mentoring and the standards you set, and other engineers trust the patterns you establish.
• You use AI coding agents as a serious part of how you build software, and understand where they fail. You've designed the context, tests, permissions and review boundaries that make agent-produced changes safe to ship.
• You make architecture and product trade-offs under ambiguity, including deciding what not to build.
• Typically 8+ years of building and operating software.

• Building internal developer platforms or shared foundations used by several teams
• TypeScript and React, Python, and PostgreSQL
• Identity and access control, or systems handling sensitive personal data
• Putting agents and unattended automation into production with technical controls
