Ironsite attacks the single biggest cost lever in construction — labor — by revolutionizing how productivity is tracked and optimized. Backed by South Park Commons.
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
More about this role
Ironsite is building the intelligence layer for the physical world. We design our own wearable hardware, deploy it alongside craft workers, and transform a shift's footage into a next-morning report. Our internal team and purpose-built models label the data overnight and deliver actionable insights to superintendents by 5 AM.
We are accelerating the speed, efficiency, and predictability of construction, especially for complex, mission-critical infrastructure projects, including data centers, LNG facilities, sports stadiums, hospitals, and other large-scale developments, by training AI models on egocentric construction footage and labor productivity data. We are built with a pro-worker philosophy at our core: we believe technology should empower the workforce, not replace it. We're working to give craft workers and project leaders better visibility into what's happening on-site, while creating a system where the reality of construction and the chaos of each day is finally available to the people running the project.
Ironsite is deployed across several of the largest active construction projects in the country. To date, we've captured more than 100,000 hours of construction footage...
