About Tacit

We are an early-stage, stealth tech startup based in San Francisco, developing innovative hardware that rethinks human-computer interaction. Backed by Purple Arch Ventures.

About the role

We are looking for a frontend product engineer to turn early ideas, prototypes, and design explorations into magical user-facing experiences. This is our first dedicated frontend hire: the interfaces you build are how people will actually experience silent speech.

  • Strong UX instincts and visual taste, with the ability to work through multiple design iterations rather than stopping at the first functional version
  • Ability to collaborate closely with technical and non-technical teammates, communicate design/engineering tradeoffs clearly, and take ownership of outcomes
