at Mach9
Full TimeAt Mach9, 3D graphics engineers push the boundaries of browser-based visualization and interaction. You’ll work closely with our platform and product teams to build powerful 3D tools that transform massive geospatial datasets into precise, usable insights for civil engineers and surveyors.
This role is ideal for engineers with 3D graphics expertise who want to tackle technical challenges involving CAD on the web, point clouds, and large-scale datasets.
You’ll be at the forefront of performance optimization, rendering techniques, and advanced geometry processing, building the foundation for tools that drive critical infrastructure design worldwide.
Design and implement performant, interactive 3D experiences for web-based geospatial tools
Optimize rendering of massive 3D datasets (point clouds, lines, vector features) in the browser
Push the capabilities of WebGL and WebGPU to support next-generation 3D workflows
Collaborate closely with product and engineering teams to integrate 3D tools into user-facing applications
4+ years of experience in 3D engineering, computer graphics, or a related field
Deep knowledge of Three.js, CesiumJS, or WebGL, or other comparable technologies
Strong understanding of linear algebra, 3D math, geometry, and spatial data structures
Ability to write highly optimized, scalable graphics code
Comfortable owning projects end-to-end
A background or interest in CAD, GIS, mapping, or point cloud processing
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.
