About the Role Join a small, early-stage team developing a wearable device for private interaction with computers. As the founding hardware engineer, you will own the hardware from the next board revision through production, helping shape a product designed for use on the move. What You'll Do • Improve PCB layout, power, RF, size, reliability, and cost across upcoming hardware revisions. • Take prototype hardware toward production by developing manufacturing, testing, supplier, and assembly processes. • Identify and resolve issues during board bring-up, real-world testing, and manufacturing. • Own hardware decisions and the quality of each device that ships. What We're Looking For • Typically 2 to 7 years of experience, with a track record of personally designing PCBs that shipped in a real product. • Experience with compact wearables, IoT devices, or consumer electronics is especially relevant. • Experience taking hardware from prototype to production, including layout, power, RF, testing, suppliers, and assembly. • Early-career engineers with strong fundamentals and demonstrated ability to work quickly with AI tools may also be a fit. • A hands-on approach and interest in owning design, testing, and manufacturing work end to end. Compensation & Benefits Salary is $70,000 to $80,000 annually. Visa sponsorship is available. Location Full-time, on-site role in San Francisco, California, United States. Candidates willing to relocate are welcome.
