Founding Product Engineer

About the Role This is a founding product engineering role at a seed-stage AI/construction-tech startup, sitting on a small, high-impact team building computer vision and AI tools that automate blueprint reading, material takeoffs, and cost estimation. You'll work end-to-end — from customer discovery to shipping — and directly shape both the product and the company's direction. What You'll Do Own features fully, from interviewing customers weekly to shipping useful iterations fast. Build intuitive UIs that make complex blueprint and hardware data accessible to users accustomed to paper-based workflows. Contribute across the stack — React frontend, Python backend, and infrastructure. Architect and build 0-to-1, taking ideas from concept to production. Translate messy domain knowledge from customers into clear, actionable product decisions. Influence product direction, not just implementation details. Apply strong product taste to how things look, feel, and work for end users. Handle the operational "schlep" that keeps an early-stage startup moving. What We're Looking For Demonstrated ability to build and ship software across the full stack; new grads with strong portfolios are welcome. Hands-on experience with React for frontend and Python for backend services and infrastructure. Track record of owning features end-to-end and engaging directly with customers. Comfort designing architecture and building products from scratch (0-to-1 mindset). Strong product taste and user-focused design sensibility. Excellent communication skills and a genuine growth mindset. Bonus: Prior founder experience or early-stage startup background (shipped something customers used or paid for). Bonus: Construction domain knowledge or clear enthusiasm for the industry. Must be eligible to work in the US (no visa sponsorship available) and willing to work on-site in San Francisco. Compensation & Benefits Salary range: $120,000 – $180,000 USD annually . Equity available at a seed-stage company. No visa sponsorship available. Location On-site in San Francisco, CA, USA . Relocation welcomed.
