If this sounds like an environment you’d love to work in, even if you only have some of the experience listed below, please apply.

What You'll Be Building

- Agentic AI for science: Systems that perform sequential decision-making and multi-step reasoning to solve domain-specific problems.
- Workflow/code generation: From natural language intent to typed, executable steps for lab instruments.
- Evaluation & reliability: Benchmarks, test suites, and telemetry to measure capability and quantify progress toward scientific goals.

What You’ll Need To Succeed

- PhD or Masters in a quantitative discipline (e.g., Computer Science, Physics, Mathematics, Engineering) with a strong background in machine learning and one domain of science (e.g. biology or materials science).
- Strong grasp of LLMs and agent architectures (planning, tool use, structured function calling, code generation) and how to adapt them to domains.
- Proficiency in modern ML frameworks (e.g., PyTorch, TensorFlow, JAX) and experience implementing scalable solutions for complex tasks.
- Comfort collaborating across disciplines and interfacing with simulations and real lab systems.

Bonus Points For

- Building long-horizon agents or RL for control/decision-making; experience with model-based or offline RL.
