## About the role

We're hiring an exceptional Founding Mobile Engineer to help build the Ironsite mobile platform for craftworkers.

## What they're looking for

- Deep experience shipping production mobile experiences, especially web-based mobile products that have to work reliably across a wide range of devices and network conditions
- Solid background in API design, third-party integrations, and real-time data and analytics surfaces. This is the kind of work where correctness, performance, and clarity for downstream teams all matter at the same time
- Systems thinking across end-to-end product architecture. You care as much about the seams between systems as the systems themselves
- Typically 5+ years of mobile-focused product experience, with a track record of shipping things you're proud of
- A background in Computer Science, Software Engineering, Mathematics, Physics, or a related technical field, or the equivalent hands-on experience
