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 our first Head of Platform to lead the team building Ironsite's platform, the product surface that turns our data into the intelligence construction teams act on every day.
What they're looking for
- Deep hands-on technical expertise across the modern web stack (React/TypeScript, Node.js, PostgreSQL, Redis, AWS). You can read, review, and write production code, and you still do. Weekly, at minimum
- Strong track record of shipping systems that scaled by orders of magnitude in throughput, users, or data volume, and doing so without over-engineering early or accumulating dead architectural weight late
- Demonstrated leadership at scale: you've hired, mentored, and managed engineering teams of at least 10 to 30 people, including managers who reported to you
- Systems thinking that spans the full stack and cross-team integration. You care as much about the seams between systems and the seams between teams
- Real ability to partner with founders and other functional leaders. You've worked directly with technical founders before, held your ground, and made them and their companies better
- 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...
