## About the role

Labelbox is the RL data factory for advancing frontier agent capabilities. We build the data, evaluations, and infrastructure that frontier labs use to train and judge their agents. We're looking for talented, experienced engineers to join us. The bar is high: engineers who have strong judgment and set technical direction, quickly build prototypes that scale into the reliable systems, and are at the frontier of agent-first engineering practices and innovating to accelerate the speed of the business.

## What they're looking for

- 4+ year track record of shipping systems customers and other engineers rely on
- You build full stack prototypes fast and they hold up. The v1 you ship becomes the foundation the rest of the team builds on
- Strong system and API design judgement
- Hard architecture and product calls land with you. You make them, defend them under pressure, and update fast when someone else is right
- You ship production code with coding agents daily. You know where they break and what it takes to make them reliable to further accelerate the team's velocity
- You set direction by being the example. Other engineers reach for your designs and your code as the reference
