About Lumia
Lumia is building the next evolution in wearable health technology: smart earrings that translate complex physiological signals into clear, actionable insights. The company combines hardware, software, machine learning, and physiology, and began by serving communities with POTS, ME/CFS, Long COVID, and orthostatic intolerance while expanding into broader consumer wellness.
The opportunity
Own and elevate Lumia's mobile experience end to end. Deliver hero features from requirements through production releases, drive seamless hardware-to-app connectivity, level up mobile team execution standards, and ship Android to feature parity with iOS. Work cross-functionally with Product, Design, Algorithms, and Firmware teams.
What success looks like
- At least one complete hero feature shipped per two-week sprint, from requirements through production with no regressions
- Bug and improvement tickets move from triage to in-release in under 6 hours on average
- 99%+ successful first-time pairing and robust background data sync
- Mobile team execution elevated through code review standards, documented best practices, and a clear operating rhythm
- Android launched at full feature parity with iOS as a stable, production-grade experience
What you will do
- Own hero features end to end from design handoff through production release, with a zero-regression standard
- Build and maintain robust BLE connectivity between Lumia earrings and the app, including background sync
- Debug complex hardware and software interaction issues across the firmware and app stack
- Set and enforce code review standards and documented best practices
- Run a clear weekly and sprint-level operating rhythm
- Lead the Android buildout to full feature parity with iOS
- Make scalable architectural decisions
- Mentor and unblock other engineers through hands-on guidance
What we are looking for
- 6+ years of mobile engineering experience with strong Flutter and Dart required
- Experience with BLE or other hardware connectivity protocols
- Track record shipping consumer apps with high reliability and quality standards
- Experience leading or mentoring mobile engineers
- Health tech, wearables, or hardware-adjacent product experience is a strong plus
How you think and work
- First-person product instinct
- Bias to building
- Intellectual horsepower
- Attention to detail
- Calibrated judgment
You live the product, lead through doing, and treat quality as your problem. Move fast when appropriate and slow down when it matters.
