## About the role

An RL environment is only useful once it runs reliably inside a lab's training stack. Every environment we build has to be packaged, sandboxed, run at scale, checked against each lab's requirements, and delivered in the format that lab's platform expects. Much of that work is still manual today, and it takes time away from the people designing environments. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- 5+ years of experience building and owning ML Platform Engineering, ideally AI related ML Platform Engineering
- Strong software engineering fundamentals and a track record of building and operating production infrastructure or developer platforms that other engineers depend on
- Hands-on experience with containers and orchestration (Docker, Kubernetes, or similar) and at least one major cloud platform (GCP, AWS, or similar)
- A working understanding of how to run untrusted code safely: isolation, resource limits, and what happens when a process fills the disk or refuses to exit
- You've owned something tedious end to end, such as a migration, a release process, or a delivery pipeline, and automated away as much of it as you could
- Extensive hands-on use of coding agents (Claude Code, Cursor, Codex, or similar), and an intuition for where models cut corners
