Founding Engineer (Full Stack)

About the Role This is a founding engineering role at an early-stage construction technology startup using AI to automate blueprint analysis, material takeoffs, and cost estimation. You'll be a core member of a small team, shaping both the product and the engineering culture from the ground up — work that directly impacts how the construction industry approaches pre-construction workflows. What You'll Do Build intuitive, polished UIs that surface computer vision model outputs to end users. Tackle complex geometry rendering, streaming systems, and sophisticated user interactions. Rapidly ship prototypes and iterate continuously based on real user feedback. What We're Looking For Proven experience taking products from 0 to 1, ideally with traction or paying customers. Strong frontend foundation in React and TypeScript , with solid full-stack capabilities. Proficiency in Python and comfort with open-ended, math-oriented problem solving. Strong CS fundamentals — an exceptional project portfolio can stand in for a formal degree. Experience as a founding engineer or early employee at a startup. Familiarity with Tailwind CSS for building responsive, utility-first UIs is a plus. Background in construction, real estate, or PDF/document workflows is a bonus. Prior founder experience or an impact-driven mindset is highly valued. Exceptional recent graduates who are fast learners and highly motivated are encouraged to apply. US Citizenship required ; visa sponsorship is not available. Compensation & Benefits Salary range: $100,000 – $180,000 USD annually . Equity is expected given the founding-team nature of the role.
