MTS - Lead Mobile Engineer

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 across seven states, now process thousands of hours of site activity every day, and maintain a worker opt-out rate below two percent. This is enabled by a workforce-first architecture that anonymizes devices, captures no audio, and never releases raw video.

Ironsite is backed by leading investors (8VC, South Park Commons, Saga Ventures) and prominent operators across technology and construction, including Eric Schmidt, Jeff Dean, Jeff Rothschild, Mark Leslie, Scott Wu, Eric Glyman, Karim Atiyeh, Russell Kaplan, and others, alongside over a dozen construction industry operators who have joined us as partners in building this.

Longer term, we believe Ironsite is the foundation for what construction becomes in the next decade. We think the systems we're building are the operating system for how the physical world gets built, and will unlock a fundamentally different way of respect for our workforce. One where craft workers are more valued, more visible, and better paid for the skill they bring, and where the industry finally has the intelligence layer that makes autonomous construction possible. Both futures start with the same foundation.

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

You'll own the mobile experience craftworkers carry in their pocket, and the field tools superintendents use to run their jobsites in real time. This is the most interactive surface Ironsite exposes to the world, and where every other team's work at the company ultimately shows up. Hardware, AI research, video pipelines, integrations with the industry's legacy tools. You'll be the person who makes sure it lands well in the hands of the people who matter most.

This is where our pro-workforce philosophy translates into product: the intelligence layer we're building meets the crews who actually build the physical world, and you'll ship meaningful initiatives that directly impact tens of thousands of craft workers and dozens of the largest contractors in the country.

The base pay range for this role is $150,000 – $250,000 per year.
