Job description

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. Featured on Business Insider businessinsider.com

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 paulgraham.com/schlep.html. We are regularly knee-deep in schlep

BONUS POINTS (IF ANY)

  • Have built something people used/paid for (founder/startup)
