Ironsite AI•San Francisco, CA

29d•$170,000 - $200,000•Onsite

About The Position

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.

Requirements

3+ years designing software products end-to-end, with a portfolio of shipped work.
Proven work on complex, data-heavy interfaces (tables, timelines, review queues, dashboards).
High proficiency in Figma.
Rapid prototyping skills (Figma, Framer, Claude Code, or a rough build).
Systems thinking: ability to ship components and patterns and write specs engineers trust.
Willingness to be on-site in SF and get on jobsites in a hard hat.

Nice To Haves

Startup experience, ideally at a design-forward company.
Data visualization depth.
Motion design experience, especially applied to interaction and state.
Familiarity with construction, industrial, logistics, or other physical-world domains.
Comfort in code (React, HTML, CSS).

Responsibilities

Own the product surface across our customer-facing platform, internal labeling tools, and the field experience around our hardware.
Work directly with founders, engineering, and the crews on site.
Design the core customer platform, showing labor productivity, safety events, and progress across a site.
Create interfaces that make computer vision output trustworthy, showing confidence, uncertainty, and source footage, and how a person corrects the system.
Design the internal labeling tools our annotation team uses for hours a day, focusing on throughput and accuracy.
Design the field-side experience around wearable hardware, including onboarding a crew and checking a device.
Develop data visualizations for dense operational reporting, including direct vs. indirect work, idle time, route traces, and crew-level trends.
Contribute to the design system, focusing on patterns and quality bar.
Develop new product bets from jobsite observation to prototype to customer-ready product within weeks.
