Bild AI, a Y Combinator W25 startup, is seeking a founding product engineer to revolutionize construction blueprint interpretation through AI. The role combines technical rigor with construction domain expertise to solve challenges in blueprint reading, cost estimation, and permit workflows. $100K - $180K compensation reflects the critical nature of the position, with equity ranging from 0.20% to 0.80%. Candidates must demonstrate mastery of React, TypeScript, and Python while embracing a customer-obsessed development approach.

The engineer will own features end-to-end, from interviewing users weekly to shipping improvements within days. Responsibilities include transforming complex blueprint and hardware data into intuitive UIs for industry professionals who traditionally work with paper plans. Cross-stack collaboration is essential, requiring experience with Tailwind CSS and infrastructure management. The role emphasizes shaping product direction rather than just execution, demanding strong product intuition and empathy for translating technical solutions into user-centric designs.

Bild AI's mission focuses on leveraging cutting-edge CV and AI techniques to streamline construction processes. The company’s model-garden architecture approach suggests ambitious technical challenges ahead, backed by top-tier VC funding. Interviews involve technical assessments, a paid work trial, and in-person interactions in San Francisco. Prior construction industry experience or product-building track records receive special consideration.

This hiring push highlights Bild AI's commitment to merging AI innovation with real-world construction workflows. By prioritizing direct customer feedback and rapid iteration, the startup aims to reduce inefficiencies in an industry critical to infrastructure development. The position represents a pivotal opportunity to influence the technical trajectory of a YC-backed venture addressing tangible societal needs through software.
