- Track record of independently leading projects end to end

- Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field, or equivalent practical experience

## Preferred Qualifications

- Experience operating services on AWS (e.g., EC2, S3) or another major cloud

- Production operations experience: observability (metrics, logs, traces), on-call participation, incident response, and postmortems

- Experience building or operating low-latency, high-throughput RPC services (gRPC or similar)
