You Will Be Responsible For

• Owning the CI/CD and QA platforms of the department end to end, from hardware and infrastructure through CI runners, build and test environments up to developer experience.
• Being accountable for the platforms' reliability, quality, scalability and cost.
• Analysing how the CI fleet and the services around it are actually used, and turning the findings into data-driven capacity, sizing and performance decisions.
• Improving and automating the tools teams use to build, test and ship, and removing recurring sources of manual work such as flaky tests.
• Contributing to the platform architecture together with engineering teams.
• Maintaining service health with monitoring and runbooks. Alerts are written into the existing company observability tenant.
• Deploying new services following best practices.
• Supporting developer requests and turning recurring ones into self‑service.
• Managing incidents end-to-end: diagnosis, mitigation, post‑mortems.
• Delivering infrastructure as code through merge-request reviews.
• Writing technical documentation for engineers across teams.
• Working with AI agents: delegating tasks and reviewing their output.
