You are a mechanical engineer who codes better than most developers and feels stifled by legacy CAD limitations. Join a tiny founding team in San Francisco to replace decades-old drafting software with an intelligent engine built from the ground up. You will architect the core logic connecting Python backends to React interfaces, directly shaping how buildings are designed.

What they're looking for

  • 2 to 10 years of experience blending mechanical engineering principles with serious software development
  • Proficiency in Python and C/C++ for high-performance geometric or physics calculations
  • Experience building user-facing applications using TypeScript and React
  • Deep familiarity with MEP workflows and the shortcomings of current industry-standard tools
  • Desire to work on-site in San Francisco as a foundational member of a new venture
