ML Research Scientist (Health & Sensing)

Eight Sleep is taking the Pod's sensing beyond sleep into a new modality, and you'll build the algorithms for it from scratch: high-frequency biosignals turned into metrics that change behavior, trained on over a billion hours of sleep data. The AI/ML team went from 2 to 11 people in ten months under David Sun (VP of AI/ML, ex-Apple). This is 0 to 1, not maintenance.

If you've spent your career on raw sensor data and wanted a product that ships to hundreds of thousands of people, you'll feel at home here.

- Build 0 to 1. Train models for a sensing modality that isn't in the product yet.

- Work the raw signal. High-frequency motion and activity time series from IMU, PPG, and optical sensors.

- Model at scale. Transfer learning and self-supervised pretraining on a billion-plus hours of physiological data.

- Ship it. Get models onto real beds with a cross-functional R&D and production team.

- Own the metric. Define a new health signal and prove it holds against physiology.
