Founding Hardware Engineer

About the Role Join a recently funded founding team as its first hardware engineer, taking a prototype device from concept through production. You will own the hardware journey, from board design and manufacturing through quality assurance, and help deliver a reliable product at scale. Your technical decisions will directly shape the product customers receive. What You'll Do Iterate on PCB revisions, optimizing layout, power delivery, RF performance, size, reliability, and cost. Move hardware from prototype toward production by addressing design for manufacturability, test strategy, supplier selection, assembly logistics, and scaling challenges. Identify and communicate risks early, using practical experience to help prevent costly mistakes. Own hardware quality and the standards applied to every unit that ships. Work directly with the founding team to build and ship the product. What We're Looking For Experience designing PCBs that have shipped in a real product, ideally in wearables, IoT, or consumer electronics. Experience taking a device from prototype to production, or strong early-career fundamentals and the ability to move quickly with AI tools. Hands-on skills in PCB layout and optimizing power, RF performance, size, reliability, and cost. Comfort with design for manufacturability, test design, supplier management, and assembly processes. Ability to anticipate and communicate manufacturing and scaling challenges; specific domain expertise is not required. Compensation & Benefits Visa sponsorship is available. Location On-site in San Francisco, California, United States.
