n The Role
nThe Ultrahuman Science Team builds the algorithms behind the Ring, M1 CGM, blood and urine biomarkers, and Performance Lab assessments. We are hiring a Senior Data Scientist to own those algorithms end to end: from the raw sensor signal to a model that is shipped, monitored, and trusted in users' hands.
nThis is a builder role with real scope. In a typical month you will improve a production algorithm, root-cause a metric users are complaining about, and stand up the data pipeline the next model needs. The common thread is ownership: you take a vague question and return a working answer, without waiting to be handed scope.

n What You'll Do
n
- n
- Own algorithms end to end: sleep staging, activity detection, sensor-derived metrics, and health scores.



You frame the problem, build the features, train and evaluate the model, and see it live n
- Ship models, not notebooks: you prove a change on our own cohort before it reaches users, and a model is done only when it runs in production and you can tell how it is behaving n
- Validate against reference standards: design evaluations against gold standards, reference devices, and study ground truth, and know when a result is real and when it is an artifact n
- Own the data layer: cohort extraction, feature pipelines, study data, and raw sensor data, so the next model starts from clean inputs n

n
n What This Looks Like in Practice
n1. Improving production algorithms - Take an existing production model like sleep staging, root-cause the failure modes against reference data, and ship a fix you can defend with numbers.
n2. Building new models - Train an activity classifier on raw sensor dat
