About Quotient Therapeutics
Quotient Therapeutics is a Flagship Pioneering company that uses somatic genomics to discover drug targets. We use high-accuracy sequencing to find rare somatic mutations in cells from non-cancerous diseased human tissue. Mutations that help cells survive or expand in a disease environment point to causal biology. We use that evidence to nominate and assess targets, and to decide whether a target should be copied (protective mutations) or opposed (disease-driving mutations).

The Role
Quotient is seeking a (Senior) Scientist, Machine Learning to build models and AI agents that turn our somatic mutation data into evidence for target discovery. A central question is what a given mutation does to a protein, and whether that effect explains why cells carrying it are selected in disease. You will build models of variant effects on protein function and connect them to genomic, single-cell, perturbation and phenotype data. You will also develop agentic AI workflows that help scientists analyse data, test hypotheses and make decisions.

This is a hands-on role on a cross-functional team. You will write clear, tested code, use modern AI tools to work faster, and work closely with the computa
