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 Design Engineer to shape how Ironsite looks, feels, and works in the hands of every person who uses it. You'll build across the surfaces our customers, our workforce, and our internal team live in every day. The dashboards project leaders open at 5 AM. The mobile experience craft workers carry in their pocket. The internal tools our labeling team uses every night. Ironsite's product surface is broad, and the details matter across every one of them.
What they're looking for
- 3-6 years of experience in design engineering or frontend-heavy product roles, with a track record of shipping work you're proud of
- Deep expertise across React, TypeScript, HTML, CSS, and modern JavaScript. You've made real judgment calls about when to reach for a framework, when to build from primitives, and when to keep it simple
- High proficiency in Figma and modern design workflows. You think in components, systems, and design tokens, not just screens
- Real product taste. You can look at an interface and articulate what's working, what isn't, and why, and you can execute on the fix yourself
- Bias toward building. You'd rather ship a working prototype than argue about a mockup, and you use fast iteration as a substitute for lengthy debate
- Comfort with tools like Claude Code, Lottie, and WebGL, or the appetite to become comfortable with them quickly
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...
