- Proven ability to design and build clean, modular, maintainable systems
- Solid testing practices across unit, integration, and end-to-end levels
Desirable Experience
- Exposure to Go or Rust
- Experience with distributed SQL databases (e.g. CockroachDB)
- Familiarity with orchestration tools such as Airflow, Temporal, or Prefect
- Background working with large-scale data or storage platforms
