Founding Product Engineer

Role Summary

We founded Bild AI to tackle the mess that is blueprint reading, cost estimation, and permit applications in construction. It's a really 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.

YOU’LL

• Own features end-to-end — interview customers every week and watch them use the product, and ship the feature they need by the next week
• Actually use the algorithms, data structures, and system design that you learned
• Revolutionize how people read blueprints today for people who've been doing this on paper. They actually thank us on customer calls and are giddy when we launch new features
• Work across the stack: React frontend, Python backend + infra
• Have ownership on product direction and approach across everything we build

WE WANT

• Great product taste — you care about how things look, feel, and work for the user
• 0-to-1 architect and builder who can work across the entire stack
• Comfort talking to customers directly and translating messy domain knowledge into clean product decisions
• Growth mindset, slope > y-intercept
• Communicate with empathy and honesty. Tell us what makes you happy/unhappy
• Don’t mind schlep https: //www.paulgraham.com/schlep.html. We are regularly knee-deep in schlep
