mach9 Software Engineer at Mach9 working on a 3D engine that renders massive LiDAR datasets into precise CAD deliverables. Build and extend 3D tools and rendering systems for surveyors and engineers.
Responsibilities
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.
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.
