About the Role

This is a founding engineering role at an early-stage wearable tech startup backed by Y Combinator, building a consumer device that reads and interprets real-time emotional states. You will own the companion iOS app end-to-end, translating sophisticated AI inference outputs into intuitive, polished experiences for users. As one of the first engineers on the team, you will shape the primary consumer touchpoint for the product and grow into a leadership role as the company scales.

What You'll Do

  • Own the companion iOS app from architecture through deployment and ongoing iteration.
  • Surface emotional-state outputs from the core AI inference model through clean, intuitive app interfaces.
  • Build and ship a polished, consumer-grade mobile experience that meets high product standards.
  • Make autonomous technical decisions as a founding engineer on a lean, distributed team.

What We're Looking For

  • At least 2 to 3 years of professional iOS engineering experience; this role is not suitable for recent graduates.
  • Strong Swift proficiency and a proven track record shipping polished, consumer-grade iOS applications.
  • Experience building data-driven apps that translate complex model or data outputs into clean, accessible interfaces.
  • Strong CS fundamentals and the confidence to own technical decisions independently.
  • Comfortable working across time zones in a distributed team environment.
  • Background in consumer wearables, health tech, or AI-powered mobile products is a plus.

Compensation & Benefits

Salary of $150,000 USD (or approximately GBP 75,000 for London-based candidates), plus up to 1 to 2% equity. No new visa sponsorship is available; visa transfers and OPT transitions are acceptable.

Location

On-site in London, England, United Kingdom. The team also has a presence in San Francisco, and some location flexibility may be considered for the right candidate.
