About the role

Instead of bolting AI onto legacy pharma systems, we're designing a new stack from the ground up.
We're hiring experienced engineers to architect and ship the first generation of Pathos' AI and data infrastructure.
This is a ground-floor role with broad technical scope and ownership.

Pathos is building a next-generation biotech with AI at the core.
We're building the largest foundation model in oncology and pairing it with proprietary AI systems, deep oncology expertise, and 200+ petabytes of multimodal data linked to patient outcomes, so we can make development decisions with more precision, much earlier.
We're well-capitalized and have the leadership to build a generational company.
How We Build Pathos does not operate like a traditional biotech.

Experience with production-grade APIs, eventing, and data engineering (cloud-native, ideally GCP/BigQuery or similar).
Prior work on LLM tools/agents, retrieval systems, or ML infra.
Experience operating within highly regulated environments leveraging patient and clinical trial data.

This will be one of the most direct applications of your technical skills to advancements in cancer research.

Bonus Points: Prior work on LLM tools/agents, retrieval systems, or ML infra.
They fail because they were tested in the wrong patients, with the wrong assumptions, in trials that couldn't answer the real question: who benefits, and why?
So therapies reach the patients most likely to benefit, sooner.

We invest in and advance our own clinical-stage programs, using our AI platform to sharpen trial design, patient selection and biomarker strategy.
