## About the role

At Posh, you'll set the technical direction for our backend systems. As Staff Backend Engineer, you own architecture across multiple services, drive platform improvements, and ship production code yourself.

## 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
