Ideal candidate

Truth-seeking researcher who owns ambiguous problems end-to-end and obsesses over data quality. You thrive in small teams turning rigorous experiments into real gains in coding agents.

Requirements

• Experience writing production-quality code in Python, PyTorch, JAX, Rust, or C++
• Able to handle ambiguous research tasks and own a research direction end to end
• Experience with RL algorithms for language models, scaling laws, or building RL environments and evals
• Experience with distributed training at scale
• MS or PhD in CS, ML, math, physics or related field, or equivalent research experience
