Responsibilities:
- Design and implement the project layer connecting resources across Magic Containers, Edge Scripting, and Bunny Database
- Build dev/staging/prod environment management so customers can ship with confidence
- Architect secrets management APIs, think secure storage, sharing, and access patterns across products
- Build observability features - unified logs and metrics - that let customers diagnose problems across multiple bunny services through a simple and powerful UX
- Create fine-grained API key and permission systems with strong multi-tenant isolation

- Solid understanding of secrets management and credential security principles
- Proficiency with RabbitMQ (or similar) for background processing and queuing
- Hands-on experience with MariaDB (or similar relational databases)

- A rigorous testing mindset: integration tests, quality gates, and edge cases
- Proficiency using AI coding tools (Claude Code, Codex, Cursor) as a daily workflow multiplier
- Full ownership mentality: from design through to production
- Good judgment on when to go deep alone and when to bring others in
- Ability to work independently in an async, fast-moving environment
- Clear communication: in code, in reviews, and in Slack
