Member of Technical Staff, Cell Therapy

Latch builds rigorous scientific benchmarks (benchmarks.bio) that measure how well AI agents perform real biology. Frontier AI labs and pharma use them to answer one question: can an agent handle the messy, multi-layer reasoning that real biological work demands?

Every benchmark is grounded in real experimental and clinical work, including designing experiments, interpreting data, reading clinical endpoints, and advancing compounds. Each is built by scientists who have done that work themselves.

We are a team of roughly 100 people in San Francisco, backed by Lux Capital, Coatue, Fifty Years, Haystack, Jeff Dean, Alec Nielsen, and George Church.

We are seeking a Member of Technical Staff for Cell Therapy to lead our benchmark and define how the field measures AI in Cell Therapy.

You will own the cell therapy benchmarks on our roadmap, decide what correct work looks like in these modalities, and shape how our agents reason about them, from design through IND.

This is a new function at Latch. You will define what it needs as much as you will execute it.

• Author and ship the cell benchmarks on our roadmap across discovery, development, translation, and long-horizon tasks.
• Be the scientific authority at Latch for all things cell therapy.
• Collaborate with scientists to design and run agentic drug programs in the wet lab, guiding discovery and development workflows.
• Work with CROs to run experiments and gather data to inform the design of our benchmarks and agents.
• Build and lead the team, establishing a function beyond yourself.

• 5+ years hands-on experience in cell therapy.
• Strong, defensible opinions about what correct work looks like in your field.
• Desire to build a function.
