## About the role

We are developing reinforcement learning systems at a scale where standard abstractions frequently fail. Unlike labs that operate primarily through high-level wrappers, we own the entirety of our RL stack. This ownership spans from low-level environment simulators and custom communication primitives to our distributed training loops and inference engines.

## What they're looking for

- BS in Computer Science or a related technical field, or equivalent industry experience
- 2+ years of relevant, hands-on industry experience
- Proficiency in Python
- Experience building or maintaining components within ML frameworks (e.g., PyTorch, JAX, or TensorFlow)
- MS or PhD in Computer Science, Mathematics, or a related field
- 5+ years of relevant, hands-on industry experience
