It’s time you own your health. Function includes 160+ lab tests and personalized protocols for instant action. Tracked over time in one secure place. Backed by Battery, General Catalyst and a16z.
About the role
You are a researcher who likes to ship and/or an engineer who insists on evidence. You have trained models on messy, irregular, real-world data and know that the evaluation design usually matters more than the architecture. You are comfortable being early; defining the problem, the dataset request and the metric before the first training run, and you communicate clearly with clinicians and regulators as well as with ML peers. You care that the model behaves well for the person on the other end of it.
What they're looking for
- PhD in machine learning, computer science, biomedical engineering or a related field with 1-2+ years of professional experience, or MS/BS with 5+ years building and evaluating ML models on real data
- Strong Python and PyTorch, experience training at scale (multi-GPU, large datasets, experiment tracking) and writing code others build on
- Rigorous evaluation instincts: statistical thinking, calibration, error analysis, and the habit of asking whether a result would survive a larger validation set
- Publication record at top ML or medical-imaging venues (e.g., MICCAI, NeurIPS, ICML, ICLR, CVPR), or equivalent evidence of research output delivered into production
- Clear written and verbal communication with technical and clinical audiences
More about this role
Function Health’s mission is to empower people to live longer, healthier lives through proactive, data-driven healthcare. We aggregate and analyze comprehensive health data — including blood tests, imaging, and longitudinal biomarkers — to provide members and clinicians with actionable, clinically meaningful insights.
We believe individuals should understand their own health deeply, in context, and over time. Our platform brings together complex medical data and transforms it into clear, trustworthy insights that support better health decisions.
Function Health is building something that has not existed before: a multimodal, longitudinal picture of health for hundreds of thousands (soon to be millions) of people. The Function proactive health dataset includes whole-body MRI, 100+ blood biomarkers, radiology reports, questionnaires and, increasingly, wearables data, all linked to the same individual and refreshed over time. The Medical Intelligence Lab (MIL) at Function exists to turn that data into an early-warning system for every member. In a nutshell, we aim to design a new model of proactive, predictive and preventative health.
The World Model team’s job is at the core of that...
