AI Research Engineer role at The Path, a consumer mental health company building AI therapists. Work covers fine-tuning and training data for models, building the eval stack (scripted tests, LLM-as-judge, human ratings, safety checks), and owning the production codebase and deployment pipelines. Team is small and in-person in San Francisco.
The Path is a research lab and consumer health company on a mission to provide therapy-grade help and coaching for anyone, anytime.
Over 3 billion people a year have a problem large enough to warrant therapy but the barriers to access - around price, time, geography, stigma, and language - are so large that less than 10% of these people are getting the help they need.
The Path exists because help shouldn’t depend on privilege, because intelligence should serve humanity, and because clarity is the first act of care.
Our purpose-built AI therapists provide evidence-based mental health support delivered through artificial intelligence, designed to get smarter with every session. The Path was built by a neuroscientist who understands how the brain actually changes. Most AI chat tools were not.
Every role here moves that work forward. Join a small, passionate in-person team in San Francisco building the AI and the clinical research behind it!
Design, train, ship, iterate on, and innovate on the AI brains behind The Path’s AI Therapist. Combine research, data science, and engineering to create models, orchestration, and evaluation systems that make therapy conversations deeply effective, clinically grounded, and safe.
