Strong Python skills (and general software engineering chops)
Hands-on experience with LLM platforms like OpenAI, Anthropic, Google
Solid background in NLP and transformers (or a hunger to learn fast)
Experience with simulations, RL, or systems that reason
Problem-solving mindset — someone who can move from idea to prototype quickly
A degree in CS, AI, Engineering, or related field (or equivalent experience)
Comfortable collaborating with a fast-moving, cross-functional team
