Job summary

Applied Geometry is an AI research lab focused on biology and health, building systems that can accelerate discovery and cure disease.

We train frontier models to reason from incomplete evidence and design experiments, with a mission to enable biological superintelligence and powerful new therapies.

Early hires will receive significant ownership, a strong compensation package, and extensive tooling to push the boundaries of AI in biology.

Qualifications

• Train AI agents through reinforcement learning to solve long-horizon problems in biology and scientific research.
• Build challenging RL environments in which agents reason over biological data, use scientific tools, generate hypotheses, design experiments, and interpret results.
• Own the full research loop: design experiments, implement methods, diagnose failures, and turn promising results into reproducible improvements.

Responsibilities

• Train AI agents through reinforcement learning to solve long-horizon problems in biology and scientific research.
• Build RL environments where agents reason over biological data and use scientific tools to generate hypotheses.
• Develop reward functions and evaluation frameworks that distinguish genuine progress from shortcuts.
• Build scalable infrastructure for agent rollouts, distributed training, and evaluation.
• Own the full research loop: design experiments, implement methods, diagnose failures, and turn promising results into reproducible improvements.
• Work closely with scientists to translate challenging biological questions into measurable objectives.
• Help define Applied Geometry’s technical stack and engineering culture from the ground up.
• Contribute to our mission of building biological superintelligence to accelerate discovery.
