About the role

What they're looking for
- 8+ years of backend engineering experience, including time as a Staff, Principal, or technical lead
- Has designed and delivered systems that span multiple services or teams with clear ownership of the outcome
- Deep expertise in backend systems: APIs, data modeling, distributed systems, event-driven architecture. Strong working knowledge of the full stack
- Proficient in technologies relevant to our stack (e.g.,Java, Node.js, PostgreSQL, MongoDB AWS or similar cloud providers)
- Has scaled platforms operationally, not just designed them on paper. You've watched performance regress under load, run incidents, and evolved architecture that was already in production
- Pragmatic about technology choices. You pick the right tool for the problem and can defend the tradeoff
