Drug development shouldn’t be guesswork, not when patients are waiting. Pathos is building a next-generation biotech with AI at the core. Not as a feature, but as the operating system for how medicines get developed. Backed by NEA.
About the role
We are hiring an engineer to architect and ship the first generation of Pathos AI and data infrastructure. Your work will power our core products and run the agents that support BD, clinical development, computational biology, and lab teams. This is an early role with broad technical scope and full ownership.
What they're looking for
- Roughly 8 or more years of professional software, ML, or product engineering experience building systems that real users depend on. We read this as a signal of demonstrated scope, not a hard gate
- Fluent in Python and TypeScript in production, and comfortable building full stack applications
- Experience with production grade APIs, eventing, and data engineering, ideally cloud native on GCP, BigQuery, or similar
- You own services end to end: architecture, implementation, testing, and observability

About the role
Pathos is building the first AI native biotech platform, one that turns massive multimodal datasets into foundation models, and those models into live agents that materially change how drug development is done. Instead of bolting AI onto legacy pharma systems, we are designing a new stack from the ground up.

If you want to build the technical infrastructure that rewires the R&D workflow, this is the place to do your career's best work. It is one of the most direct applications of your engineering skill to advances in cancer research.
What You’ll Build
- Build AI agents and copilots for internal teams across BD, clinical, computational biology, and lab.
- Build robust data pipelines into a governed warehouse and knowledge graph.
- Build MCP style servers and tooling so agents can safely talk to internal systems.
- Work across the full product lifecycle:...
