## About the role

Think of this as a product engineer role — but the product is everything underneath. For a stateful, multiplayer AI agent that takes real actions in the world, infrastructure is the user experience. When a meeting gets scheduled in 800ms instead of 4 seconds, when an email never gets dropped, when our agent recovers gracefully from a flaky third-party API — that's a feature users feel. You'll ship those features.

## What they're looking for

- 4+ years of software engineering experience, with significant time on backend or infrastructure
- Product sensibility — you reach for user-facing metrics first, and you can tell the difference between an infra problem that matters and one that doesn't
- Deep with databases — you can read query plans, find the bottleneck, and know when to fix the query vs. fix the schema vs. fix the architecture
- Have run production services and owned the pager — comfortable in an incident, methodical in the postmortem
- Familiar with job queues, async processing, or event-driven systems, and have opinions on when each is the right tool
- Interest in developer tooling and how AI changes the way engineers should work
