High Standards. No Apologies

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. We’re a team that puts in the extra effort, not because it’s required, but because we care about the impact of our work.

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  you’re looking for something easier – this isn’t it.

We are looking for a Senior Sensor Engineer (Biometric & Physiological Sensing) to help design our future generation products. This role will be instrumental in building the next generation of high performance bio-sensing and environmental sensing systems for the Eight Sleep product ecosystem. This role will interact closely with R&D and Hardware engineers, and will see their work productized to directly impact our members and our business.

• Lead the development of next generation biometric sensor systems
• Rapidly develop functional prototypes, including sensor, electrical, mechanical, and firmware components
• Perform data analysis and preliminary algorithm development to assess feasibility and implement solutions
• Create and execute sensor development plans from concept to production readiness for systems that must operate nightly, autonomously, and reliably across 200k+ users
• Coordinate with product development and software/firmware teams to incorporate designs into production

• 4+ years of industry experience developing sensing systems, demonstrating a track record of innovation
• System level mindset, proficiency in EE and ME prototyping (e.g. PCBA, 3D rapid prototyping)
• Experience with software development for signal processing and prototyping embedded systems
• Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Biomedical Engineering, or equivalent experience
