About

Rudus is an AI-powered takeoff platform for structural and site concrete. We accelerate concrete takeoffs by 70%+ with AI trained specifically on structural and civil drawings- counting, measuring, and reading sheets so estimators can focus on winning bids.

The Role

You'll be one of the first engineers, shipping across the entire stack: drawing intake and rendering, AI-powered element detection and autocomplete, real-time collaborative editing, schedule interpretation, and exports into estimators' bidding workflows. You'll work directly with customers and see your code run on real bids within days of shipping.

What You'll Do

  • Own features end-to-end: design, build, ship, and iterate based on direct customer feedback
  • Build AI systems that read construction drawings, schedules, details, and plan views; and turn them into takeoff quantities
  • Develop real-time collaborative tooling: multiplayer editing, version history, cloud workspaces
  • Work on geometry-heavy problems: scale detection, pattern-matching footings, auto-completing curb runs and slab boundaries
  • Shape engineering culture, architecture, and hiring as the team grows

What We're Looking For

  • Strong generalist with production experience in Python and TypeScript
  • Comfortable owning ambiguous problems from idea to deployed feature
  • Bias toward shipping fast and iterating with users
  • Bonus: experience with LLMs/computer vision, canvas/geometry rendering, or construction tech
