MTS - Platform Engineer

About Ironsite 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 [... source excerpt omitted ...] t makes autonomous construction possible. Both futures start with the same foundation. The Role We're hiring an exceptional Senior Engineer to help build the Ironsite platform. You'll build and ship the product that turns our video data into something construction teams act on every day, including the dashboards project leaders open at 5 AM, the labor-management tools superintendents run their entire jobsite on, the mobile experience craft workers carry in their pocket, and the integration layer that connects Ironsite to the software the industry already lives in. You'll own meaningful initiatives that directly impact tens of thousands of craft workers and dozens of the lar [... source excerpt omitted ...] keep hundreds of subject-matter experts labeling thousands of hours of video every night at a bar high enough for our research team to train and evaluate on. Technical Challenges You'll Solve Building trustworthy reports on top of high-volume model output. Every night, our system processes thousands of hours of jobsite video into production reports that superintendents open before the crews arrive on site. That deadline is real, the reports have to be right, and the underlying model outputs are messy at the scale we operate. You'll build the data infrastructure and reporting layer that makes this happen without fail. Integrating with an industry running on legacy tools. Iron
