About Ironsite


Construction is one of the most complex and labor-intensive industries, spending $7 trillion annually on labor, but productivity losses cost $1.6 trillion per year due to outdated management tools.

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).

The Role

We’re looking for a Senior Design Engineer to help shape the future of our platform—someone who cares deeply about craft, moves fast, and takes real ownership over what they build.

What You’ll Do
  • Build and evolve core platform UI across customer-facing and internal products
  • Develop and maintain a cohesive, high-quality design system
  • Design and implement thoughtful, polished interactions
  • Prototype and ship new features end-to-end
  • Collaborate closely with design and engineering to raise the bar on product quality

What We’re Looking For
  • 5–8 years of experience in design engineering or frontend-heavy product roles
  • Strong experience with React, HTML, CSS, and JavaScript
  • High proficiency in Figma and modern design workflows
  • Experience with tools like Claude Code, Lottie, and WebGL
  • Startup experience preferred
  • You have a bias toward building and iterating quickly. You have strong product taste and care about details. You take pride in your work and own outcomes, not just outputs.

Nice to Have
  • Experience with data visualization
  • Motion design experience

Requirements
  • Portfolio of shipped work required

Compensation & Perks
  • Competitive salary + equity
  • Daily catered breakfast and lunch
