Founding Product Engineer

About the Role

This is a founding-team product engineering role at a seed-stage construction AI startup, sitting on a small, impact-driven product team. You will shape and ship core features end-to-end, working directly with customers to bring AI-powered blueprint analysis and cost estimation tools to the people who build housing and infrastructure.

The work is meaningful

faster, cheaper construction means more homes, hospitals, and schools.

What You'll Do

• Own features fully, from weekly customer interviews through to production delivery the following week.
• Build UIs that make complex blueprint and hardware data feel intuitive for users coming from paper-based workflows.
• Contribute across the stack, working on a React frontend and a Python backend and infrastructure.
• Architect and build new product capabilities from zero, taking ideas from concept to production.
• Translate messy domain knowledge gathered from customers into clear, well-scoped product decisions.
• Shape product direction alongside the team, not just implementation details.
• Handle the operational and logistical work that keeps an early-stage startup moving.

What We're Looking For

• Demonstrated ability to ship full-stack features using React on the frontend and Python on the backend; all experience levels considered, including recent graduates.
• A track record of owning features end-to-end, from customer discovery through production delivery.
• Strong product taste and user-focused design sensibility.
• Experience or clear aptitude for 0-to-1 architecture and product building.
• Excellent communication skills, a growth mindset, and comfort with rapid iteration.
• Genuine motivation to make housing and infrastructure more affordable, not just to maximise compensation.
• Bonus: previously built a product that people used or paid for (as a founder or early startup employee).
• Bonus: construction, blueprint, or estimation domain experience or a clear interest in the industry.
• Bonus: experience applying AI or computer vision to construction workflows.
• US work authorization required; visa sponsorship is not available.
