Mobile product
Mobile Engineer
Build the field-workforce product used by cleaners, maintenance teams, runners, and operators in the physical world.
The mandate
Make operational work clear and reliable in the places where connectivity, attention, and time are constrained.
The exact shape will evolve. We care more about the outcome you can own than preserving the boundaries of a job description.
The work
What day to day actually looks like.
The mix changes with the company’s bottleneck, but these are the recurring loops you should expect to own.
- 01
Study how cleaners, maintenance teams, and runners complete work under real field constraints.
- 02
Build and polish the Expo and React Native experience across iOS and Android.
- 03
Design offline-first data, sync, notifications, and recovery paths for unreliable connectivity.
- 04
Test on real devices, inspect performance, and own the release from implementation through rollout.
The outcomes
What success starts to look like.
- Make a core field workflow faster and easier to complete correctly.
- Keep critical work dependable through weak connectivity and interrupted sessions.
- Establish a release and quality loop that lets the mobile product improve quickly without surprising the field.
The person
Signals we look for.
You do not need to match every line. Show us evidence of slope, ownership, and the quality of judgment you bring to unfamiliar problems.
