- Proven experience with databases and performance tuning (Postgres, Clickhouse)
- Infrastructure and reliability skills (Datadog, AWS, CDK)
- Understand how to design systems with safety and fail-safe operations in mind
- Are comfortable with APIs, event-driven architectures, and stateful services
- Care deeply about observability: metrics, logs, tracing, error handling
- Take ownership across the stack — from frontend surfaces down to databases and queues
Responsibilities
- Build and maintain internal services for enforcement, throttling, and policy rules

- Ensure all enforcement actions are traceable with logs, metrics, and audit trails
Other
- Bring 5+ years of software engineering experience
