Turn reality capture into complete deliverables faster. Mach9 automatically drafts features from scans at centimeter-level accuracy and infrastructure scale. Backed by Y Combinator.
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

This role is ideal for an early-career engineer with a strong foundation in 3D math who wants to work on a real production renderer, not a demo.
You'll do well here if you enjoy digging into difficult technical problems and building software that stays fast and reliable on large, messy real-world datasets. When the right approach isn't obvious, you'll research how others have solved similar problems, test your assumptions, and choose a practical solution. Our engineers are trusted to own their work and drive meaningful outcomes.
Build 3D tools that surveyors use to inspect point clouds and create precise engineering drawings
Extend our point-cloud renderer and GPU picking system
Solve geometry problems behind clipping, snapping, construction planes, and camera controls
