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.
