This is not a management role, but candidates with system-wide thinking and technical mentorship experience are welcome.

• PostgreSQL experience (schema design, performance tuning)

• Exposure to caching (Redis), Docker, and AWS or similar infra

Nice-to-Have

• Async Rust (Axum or similar), Terraform, DataDog
