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

We founded Bild AI to tackle the mess that is blueprint reading, cost estimation, and permit applications in construction. It's a tough technical problem that requires the newest CV and AI approaches, and we’re impact-driven to make it more efficient to build more houses, hospitals, and schools. Featured on Business Insider.

You’ll

• Shape what we build next, not just how we build it

We want

• Great product taste — you care about how things look, feel, and work for the user
