About the Company

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.

About the Role

We're looking for a Senior Software Engineer to a new team we are building that focuses entirely on internal developer experience. You'll shape how Aiven engineers write, test and ship code, from development environments and internal tooling to CI/CD pipelines. Every improvement you make lands directly in the daily work of every engineering team at Aiven. We want a generalist who knows software engineering best practices, is equally comfortable writing a fast, robust shell script and managing cloud infrastructure, and wants to build up a team from day one.

Responsibilities

  • ● Work with engineering teams to identify and prioritise concrete problems, then fix them.
  • ● Own and improve our CI/CD pipelines.
  • ● Build new developer tooling, or pick the best existing tools, and drive their adoption.
  • ● Set sensible defaults for the whole organisation, such as project templates, testing conventions and documentation.
  • ● Help shape how humans and AI agents develop safely side by side.
  • ● Professional Experience: Several years in professional software engineering teams, shipping and maintaining software in production.
  • ● Ownership Instinct: You're the person who fixed the flaky build, wrote the onboarding script or cleaned up the pipeline because it was slowing your team down, even when nobody asked.
  • ● Infrastructure: Hands-on experience with Linux, containers and Infrastructure as Code.
  • ● Communication: Fluency in English, written and verbal.
  • ● Observability (nice-to-have) : Experience with observability tooling.
  • ● UX Sensibility (nice-to-have) : Familiarity with user experience or product design, or a habit of treating your fellow engineers as users.
  • ● Open-Source Data Technologies (nice-to-have) : Familiarity with open source data technologies such as Apache Kafka , PostgreSQL or ClickHouse .
  • ● 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:
  • ● Our global benefits are designed to help you thrive and grow, personally and professionally:
  • ● Participate in Aiven's equity plan.
  • ● Balance work and life with our hybrid work policy.
  • ● Choose the equipment you need to set yourself up for success.
  • ● Use your Professional Development Plan budget for learning opportunities.
