- Write production-ready code with meaningful metrics, traces, logs, and at least 80% automated test coverage.
- Maintain service SLOs with alerts and dashboards; participate in on-call and contribute actionable post-mortem follow-ups.

- Independent delivery of small-to-medium features from design through deployment within a sprint cadence.
- Familiarity with on-call responsibilities, runbooks, and operational reliability.
- Clear communication, adaptability, and ability to execute loosely scoped work with moderate guidance.
Technology stack
- The stated technology stack includes .NET Core (C#), SQL/Postgres, ClickHouse, AWS, and DataDog.
Bonus experience
- Cloud platforms, distributed systems, developer workflow improvements, documentation, or internal tooling are bonuses.
- Real-time bidding, ad serving, or similar latency-sensitive, high-throughput systems experience is a plus.
