Join us and lead the movement that’s transforming how the world sleeps and what we’re all capable of when we wake up.
The opportunityWe’re looking for an intern on the hardware engineering team to troubleshoot field units and support testing of prototypes. You’ll be part of a small, mission-driven team working on novel hardware products. We’re growing quickly so there are ample opportunities for challenge and growth.
This internship starts in Fall 2026 and requires being on-site in our San Francisco office.
How you’ll contributeTroubleshoot issues seen in the field by customers by analyzing data from units, talk to customers as needed to understand failures, and work with the engineering team to determine root causes and corrective actions.
Support product development teams with prototyping and testing.
Build software and AI tools to facilitate diagnosis of hardware failures.
Strong written and verbal communication skills.
Familiarity with mechanical, electrical, and software systems to understand possible causes of failures.
Familiarity with interpreting data and sensor readings.
Familiarity with root cause analysis, DOE, and quality measuring techniques.
Pursuing or recently completed a BS in Mechanical or Electrical Engineering, or equivalent.

What We Do
Eight Sleep is building a predictive health platform powered by sleep, now used by 200k+ members nightly across 30+ countries. Our products combine hardware, software, AI, and biometric sensing to turn the bed into an always-on system that can measure physiology, regulate temperature in real time, and adapt throughout the night to improve sleep, recovery, and long-term health. The impact is already measurable. In studies, the Pod has improved sleep quality by up to 32%, helped users fall asleep up to 44% faster, reduced nighttime disturbances by 23%, improved cardiovascular recovery markers like heart rate variability and resting heart rate, and increased cognitive performance, including a 9% improvement in processing speed. More recent research also found a 56% average reduction in nighttime hot flashes among peri- and post-menopausal women. Even after becoming profitable in 2025, we're still early. We've raised over $150M across recent rounds, including a $50M raise at a $1.5B valuation, to accelerate an ambitious roadmap into predictive, AI-driven health.
Why Work With Us
Eight Sleep develops integrated hardware, software, and ML systems that sense physiology and regulate the sleep environment in real time. The product operates nightly, creating a closed-loop system that improves sleep, recovery, and long-term health. If you're looking to work at the edge of what is possible, and make measurable impact
