Job summary

Build Inc. seeks a Computational Design Engineer to own how Build looks, feels and works, shipping production code.

You will design the product and the 3D and site design tools behind it, then build them yourself: production React and TypeScript on the front end, and Rhino, Grasshopper and Python for the geometry underneath. Our clients make big decisions about land, power and buildings, so you will ensure the output is clear enough to act on and defend in investment committees.

Qualifications

• Trained in architecture, product or computational design and capable of writing production code.
• Experience designing end-to-end product flows and geometry-driven UI.
• Established ability to ship production front-end (React/TypeScript/Next.js).
• Experience with 3D geometry tools (Rhino, Grasshopper) and scripting (Python/C#).

Responsibilities

• Own the look, feel, and behavior of Build's product in production code.
• Design and build the 3D and site design tools behind the workflow.
• Develop frontend in React/TypeScript and geometry logic in Rhino/Grasshopper/Python.
• Contribute to the design system and ensure consistency across surfaces.
• Turn maps and site data into clear, decision-ready screens and reports.
• Collaborate with engineers and domain experts to deliver fast, high-quality outputs.
