Java Developer for Continuous Integration and Deployment Systems Team

Arcadia CI is Yandex's internal CI/CD orchestrator system, analogous to GitHub Actions. A high-level entry point for everything related to automating the development process in the monorepository: building, testing, and deployment.

CI monitors all commits in all branches and pull requests, filters changes, builds projections onto the service structure, launches, tracks, and aggregates the results of all checks and regular processes, and allows managing releases, hotfixes, rollbacks, and their composition.

Our work combines big data, high load, and complex product development. A corresponding balance is present in the tasks: there are both optimizations and refactorings, as well as business features with research.

What tasks await you

Developing a common solution for CD We strive to provide an IaC-first platform for managing deployments, on par with external counterparts like Argo CD, but closely integrated into the internal infrastructure and reliably meeting the needs of tens of thousands of developers at Yandex's scale and with its technologies.

Convenience and accessibility of checks The pull request is the primary workspace of every developer. We focus on ensuring our systems minimally distract people from their direct tasks, promptly delivering the results of automated builds and tests at the most suitable moment, including through the use of AI.

Implementing SRE practices In our hands is a critical service at the heart of the development processes of a huge company. Every downtime results in a waste of valuable business team time. Maintaining trust and transparency for our users at a high level 24/7 is a non-trivial task, which modern SRE practices help us solve.
