Bild AI (YC W25) Is Hiring a Founding Product Engineer

Bild AI is an early-stage YC-backed startup tackling blueprint understanding, cost estimation, and permit workflows for Division 8 doors, frames, and hardware using modern computer vision and AI models. Founded in 2024 (W25) with a nine-person team and noted coverage in Business Insider, the company emphasizes a model-garden approach to parsing complex construction drawings to speed building of houses, hospitals, and schools. Founders Roop Pal and Puneet Sukhija position the product as customer-obsessed and technically ambitious, having raised from top VCs pre-demo day and seeking engineers who can break new ground in a messy domain.

The role is for a founding product engineer who will own features end-to-end, run weekly customer interviews, and rapidly ship solutions. Candidates should be full-stack (React frontend; Python backend and infra), strong in product taste, and comfortable as a 0-to-1 architect who translates domain knowledge into clean UX for users accustomed to paper workflows. Compensation is $120K-$180K plus 0.10%-0.40% equity; SF-based, full-time, in-office, and US-visa eligible only. Interview steps: 15-minute intro, 1-hour whiteboard, 1-hour coding, and a 3-5 day paid trial. Bonus if you’ve built a paid product, have construction experience, or are impact-driven. Messaging should briefly explain fit and include the founder’s favorite fruit.
