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 Head of People to build the recruiting function that will scale Ironsite from 40 people to 200 in the next eighteen months. You are the first talent hire at the company. That means you own everything from full-cycle recruiting to sourcing strategy to interview design to offer close to onboarding, and you build the systems, tooling, and playbook that will let the next talent hires operate at scale when they arrive. Everything you build becomes the foundation the rest of the talent org runs on.
What they're looking for
- 6-10+ years of full-cycle recruiting experience at fast-growing technology companies, with a track record of hiring for hard-to-fill technical roles at pace
- Deep experience recruiting AI research talent (research scientists, ML engineers, applied researchers) against top labs. You know the community, the sourcing channels, the compensation dynamics, and how to close
- Prior experience as a founding or early recruiting hire at a startup that scaled from 30-40 people to 150+. You've built the function before, not just executed within one
- Full-cycle ownership from sourcing through close. You are not a coordinator, and you are not a manager who has stopped recruiting yourself. You still hunt
- Bias to action. You'd rather send the cold outreach than wait for it to feel perfect, and you'd rather push a hiring manager to make a decision than let a candidate go stale
- Genuine intellectual honesty about candidates and process. You know when a candidate is a real fit and when they're not, and you don't tell hiring managers stories about pipeline that isn't there
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...
