Founding Engineer (Full Stack)

About the Role

This is a founding engineering role at a seed-stage construction technology startup building AI-powered tools that automate blueprint analysis, material takeoffs, and cost estimation. You will be one of the earliest engineers on a small, high-ownership team, shaping both the product and engineering culture from the ground up. The work directly supports making housing and infrastructure development faster and more affordable.

What You'll Do

• Build intuitive, polished UIs that surface computer vision model outputs to end users.
• Tackle complex geometry problems, streaming systems, and sophisticated user interactions.
• Ship prototypes rapidly and iterate continuously based on real user feedback.

What We're Looking For

• Strong React and TypeScript skills paired with full-stack engineering ability.
• Python proficiency and comfort solving open-ended, math-oriented problems.
• Demonstrated ability to take a product from 0 to 1, ideally with real traction or paying customers.
• Solid computer science fundamentals, or an exceptional project portfolio demonstrating equivalent ability.
• Experience as a founding engineer, early startup employee, or founder is a strong plus.
• Familiarity with construction, real estate, or PDF workflows is a bonus.
• Proficiency with Tailwind CSS is a nice-to-have.
• Empathetic, honest communicator who is genuinely motivated by impact over compensation.
• Exceptional new graduates with strong hustle and a quick learning curve are welcome to apply.
• US citizenship required; visa sponsorship is not available.
