About the Role
This is a founding engineering role at a Y Combinator–backed wearable AI startup, where you'll own the companion iOS app end-to-end — translating real-time emotional-state inferences into intuitive, consumer-grade experiences.

- Make autonomous technical decisions as a founding engineer, helping to shape the long-term platform architecture.
- 3+ years of professional iOS development experience with Swift and a proven track record of shipping production-ready consumer iOS apps.
- Strong full-stack capabilities spanning mobile development and backend API integration.
- Experience integrating machine learning model outputs or inferences into a mobile UX.
- Demonstrated end-to-end ownership of mobile features, from concept through release and ongoing iteration.
- Proficiency delivering polished, performant consumer UI/UX with smooth user experience.
- Strong CS fundamentals and comfort making independent technical decisions.
- Ability to collaborate effectively across time zones on a distributed team.
- Work authorization in the UK or US required; new visa sponsorship is not available (H-1B transfers considered).
Base salary of $150,000 USD (or approximately £75,000 GBP for London-based candidates), plus up to 1–2% equity
. No new visa sponsorship; H-1B transfers may be considered.
Flexible — remote or on-site. Primary office location is London, UK
, with a presence also in San Francisco, CA. Candidates must be comfortable working across time zones.
