Software Engineer, AI Agents
Foresite Labs, San Francisco, CA +1
The role
We're hiring a software engineer to help create the data pipelines, machine learning infrastructure, and agentic systems that power our science. On the agentic side, that means writing the code that runs the loop an AI agent operates inside, not one-off prompts — designing how agents plan, call tools, orchestrate sub-agents, keep memory, check their own work, and decide when they're done, then shipping them into production to do real work across our genetics and drug-discovery pipeline. This is "loop engineering": the model writes the prompts; you build and harden the machinery around it.
