Founding Product Engineer

About the role

About the Role Join a small, impact-driven product team at a seed-stage AI startup transforming the construction industry. The company builds computer vision and AI solutions that automate blueprint reading, cost estimation, and permit applications — helping teams build more homes, hospitals, and schools faster and with less waste. As a Founding Product Engineer , you'll have an outsized influence on the product, working directly with customers and shaping core features from concept to production. What You'll Do Own features end-to-end — interview customers weekly and ship meaningful iterations on a tight feedback loop. Build intuitive UIs that make complex blueprint and hardware data accessible to users accustomed to paper-based workflows. Contribute across the full stack: React frontend, Python backend, and supporting infrastructure. Act as a 0-to-1 architect — taking raw ideas from concept through to production. Translate messy, domain-specific knowledge from customers into clear, actionable product decisions. Help shape product direction, not just implementation details. Apply strong product taste to how things look, feel, and work for real users. Handle the operational "schlep" that keeps an early-stage startup moving forward. What We're Looking For Required: Demonstrated ability to build and ship full-stack software (React + Python); open to all experience levels — new grads encouraged. Experience owning features end-to-end, from discovery through deployment. Track record of regular customer interviews and translating domain knowledge into product decisions. Experience building and maintaining Python-based backend services and deployment/infrastructure. Strong product taste and user-focused design sensibility. Excellent communication skills, empathy, and a growth mindset. Ability and willingness to work in-office in San Francisco full-time. Must be eligible to work in the US (US citizen or valid work visa) — visa sponsorship is not available . Nice to Have: Previously built and shipped a product used or paid for by real customers (founder or early startup experience). Construction domain experience or a clear, genuine interest in the industry. Experience at an early-stage or high-growth startup. Compensation & Benefits Salary: $120,000 – $180,000 per year Early-stage equity opportunity as a founding team member Direct impact on product direction and company culture from day one Location This is a full-time, on-site role based in San Francisco, CA . Candidates must be willing to relocate to San Francisco if not already local. Remote work is not available for this position.
