ML Research Scientist (Health & Sensing)

San Francisco, United States
Full-time

About the role

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.

About Eight Sleep

Eight Sleep is the first sleep fitness company. 1 in 3 people are sleep deprived, and the CDC calls insufficient sleep a public health epidemic. Our mission is to fix this and fuel human potential through optimal sleep.

In 2019, we launched our temperature-controlled smart bed, The Pod. We now power the sleep of over 60,000 people every night, including world-class athletes like F1 champion Lewis Hamilton and baseball MVP Aaron Judge. We've been consistently recognized as one of Fast Company’s Most Innovative Companies, including the top wellness company for 2023.

We've raised $90M from leading Silicon Valley investors, and are working on exciting new products that go beyond temperature control of the bed.
