## About the role

We're hiring a Head of ML Engineering to own how our research team's models get tested, labeled, shipped, and run in production. Research builds the models. You'll build everything around them: the systems research uses to A/B test models on live jobsites, the tools our labelers use every night, the data tooling research trains from, and the orchestrator and inference stack that deliver reports by 5 AM. You'll start as a hands-on tech lead and grow the team from there. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- 7+ years of software engineering, with at least 3 years building production ML systems
- Experience leading a small team as a tech lead or manager while still shipping a lot of code yourself
- You've built experimentation or A/B testing systems in production
- You've built internal tools that non-engineers use every day, such as labeling tools or operations tools
- Hands-on experience with MLOps and GPU inference
- You can debug across the stack: from a wrong number in a customer report back to the model, the data, or the pipeline
