## About the role

You'll work on the stack that gets a policy from "recorded a human doing it" to "running on a line." Depending on your strengths and what's on fire, that could mean: Policy work. Imitation learning (ACT, diffusion policies), visual servoing, observation-space design. Our experience matches the published literature here: what you condition the policy on matters more than which backbone you pick.

## What they're looking for

- Strong Python. You've written code other people had to maintain
- Comfort with PyTorch — you can read a training loop and know where to put a breakpoint
- Enough Linux and git to be self-sufficient
- Empirical instincts. When something doesn't work, your first move is to isolate a variable, not to change three things and re-run
- Currently enrolled in CS, EE, ME, robotics, or equivalent — or you can demonstrate the skills some other way. We care about the second clause
- Hands on real robots: ROS/ROS2, arm kinematics, cameras, calibration
