## About the role

The last ten seconds of an auction are the whole product. Hundreds of people who have been watching one card for a week all arrive at once, every one of them refreshing, every one of them bidding.

## What they're looking for

- 5+ years building and scaling complex applications — Python, Postgres, AWS or comparable cloud infrastructure
- Modern frontend mastery. Deep experience with React, TypeScript, and building high-performance real-time UIs. Real-time is the operative word: this is not a CRUD screen
- Reliability under pressure. A track record of building systems that stay up when the stakes and the traffic are highest. You've been paged during the worst possible ten minutes
- AI pragmatism. You've taken LLMs or computer vision models and turned them into practical, user-facing features that solved a real business problem. Not a demo
- Product instincts. You don't build what's on the ticket. You understand the collector mindset and build things that delight them — and you can explain the why behind past work before you explain the how
- High agency. You thrive where you're expected to find the highest-leverage work and go execute it without a hand-holding manual
