## About the role

At Mach9, Digital Surveyor turns massive LiDAR datasets into precise CAD deliverables, automating work that currently takes surveyors and engineers weeks. Making that possible in a browser requires a 3D engine that can render tens of millions of points while supporting CAD-grade picking, clipping, snapping, and measurement. You'll work directly on that engine and the tools built on it. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- A strong foundation in 3D math and spatial reasoning, including transforms, planes, and projections
- Experience building software through coursework, personal projects, internships, or full-time work
- The ability to read and change code you did not write
- Attention to correctness and performance
- Sound judgment about when to refine a solution and when to ship it
- Experience with TypeScript and browser graphics, or comparable experience writing performance-sensitive graphics code in a statically typed language
