Senior Mechanical Engineer

1 in 3 US adults have poor sleep, which raises the risk of diabetes, cardiovascular disease and dementia. At Eight Sleep, we’re building electromechanical systems that change how you sleep, not just tell you how you slept. Continuous sensing drives real-time temperature, head elevation, and sound changes, with clinically proven results: 34% more deep sleep and cardiovascular recovery similar to 12 weeks of exercise training. To do this, we solve actuation, sensing, thermal, fluids, AI and manufacturing challenges across hundreds of thousands of units a year - in a form factor that needs to blend seamlessly into the home.

Over 400k members in 34 countries sleep on our products, from health-conscious consumers to professional athletes. Fast Company has named us one of its Most Innovative Companies four times, and TIME has twice named our products to its Best Inventions of the Year.

We operate with intensity because our mission demands it. At Eight Sleep, we bring the same mindset as the world’s top performers: focused, relentless, and always pushing to be in the top 1% of our craft. Think Kobe Bryant’s mamba mentality, applied to bold ideas, next-gen tech, and flawless execution. This isn’t a 9-to-5. Our team is deeply committed, often putting in 60+ hours a week –not because we’re told to, but because we’re invested. We’re here to build fast, push limits, and deliver without compromise. If you thrive under pressure and want to do the most meaningful work of your career, you’ll feel right at home. If you’re looking for something easier –this isn’t it.

We’re looking for an experienced Senior Mechanical Engineer to develop products from concept through to production. You’ll be part of a small, mission-driven team and have significant ownership over decisions. We’re growing quickly so there are ample opportunities for career growth.
