Staff Platform Engineer

Ironsite AI•San Francisco, CA

2d•Onsite

About The Position

Ironsite leverages wearable cameras combined with human labeling and AI vision language models to drive on-site productivity, safety & training for crafts workers. We put cameras on construction workers' hard hats and vests to analyze what's actually happening on job sites. We help teams cut labor costs, improve safety, and finish projects faster. We have captured ~50,000 hours of construction footage across 7 states and just partnered with the nation's #2 hard hat manufacturer. We’ve raised over $13M in seed funding from 8VC, South Park Commons, and 30+ leading operators and technologists, including Eric Glyman (Ramp), Jeff Dean (Google), and Scott Wu (Cognition). We're seeking an exceptional Staff Engineer to help build out our Platform. You'll build and scale the product that turns our video data into something construction teams act on every day: the dashboards project leaders read by 5am, the labor-management tools superintendents run their jobsites on, the mobile experience craftsworkers carry in their pocket, and the integrations that connect Ironsite to the software the industry already lives in. You'll own critical initiatives that directly impact thousands of construction workers and dozens of major contractors, and help mentor and grow the team as we scale.
