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.

Mach9 is transforming civil infrastructure design with AI-powered geospatial tools. Our platform accelerates the creation of engineering deliverables from raw data, cutting manual drafting time by 96×. Trusted by global leaders in engineering and construction, we're backed by Y Combinator, Quiet Capital, and top founders and executives from Cruise, Autodesk, Adobe, and DoorDash.
We believe the needs of a startup benefit from an in-person culture. The team works out of our office in SoMa, with the flexibility to work from home when needed.
