# Software Engineer - 3D Graphics at Mach9

- **Company:** Mach9
- **Location:** San Francisco, CA
- **Compensation:** $130k–$180k
- **Employment:** full-time
- **Posted:** 2026-10-21
- **Last confirmed live:** 2026-11-08

## Job description

## 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. 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. Where you will make an impact

- 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
- Find and fix performance problems that appear with large real-world datasets
- Improve the shared rendering and interaction systems behind our CAD tools

## What you bring

- 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
- The initiative to investigate problems, ask useful questions, and finish what you start

Bonus experience

- WebGL, GLSL, Three.js, Cesium, or another real-time graphics system
- Point clouds, geospatial data, or large-coordinate rendering
- Experience applying geometry, spatial algorithms, or numerical methods to open-ended problems with noisy data and real-world tradeoffs
- CAD, mapping, visualization, robotics, or game-engine projects

## About Mach9

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.

## About Mach9

## Company Overview
- **One-liner**: Mach9 builds AI-native CAD software that automatically transforms LiDAR point clouds into engineering-grade 3D maps, accelerating infrastructure design and surveying workflows.
- **Entity Type**: Private (Seed stage)
- **Headquarters**: San Francisco, California, USA
- **Founded**: 2021
- **Founders**: Alexander Baikovitz (CEO), Zachary Sussman (CTO), Haowen Shi, Michael M. – four researchers from Carnegie Mellon University's Robotics Institute.

## Core Business
- **Primary industries**: Civil infrastructure, surveying & geospatial services, transportation, telecom, utilities, architecture/engineering/construction (AEC).
- **Target customers**: B2B. Enterprise clients include top engineering firms (Langan, Olsson, Woolpert, HDR, Michael Baker International), major state Departments of Transportation (DOTs), and utility companies.
- **Mission/purpose**: "Accelerate how teams model and understand the world" – providing the fastest, most accurate automated feature-extraction technology for infrastructure projects.

## Products & Services
- **Digital Surveyor (DS2)**: AI-native, web-based CAD platform for automated feature extraction from LiDAR point clouds. Offers AI-assisted extraction (curbs, pavement edges, guardrails, utility poles), manual tools, and direct export to AutoCAD, MicroStation, and ESRI. Data-agnostic ingest pipeline supports scanners from RIEGL, Trimble, Leica, NavVis. Type: SaaS.

## Market Standing
- **Valuation**: Not publicly disclosed.
- **Key Metric**: Total Funding – **USD $14,425,000** (as of early 2026).
- **Notable Investors/Partners**: Y Combinator (Summer 2021 batch), Quiet Capital (led $12M Seed round, Nov 2024), Tiger Global Management (led $2.3M Seed round, Dec 2021), and top executives from Cruise, Autodesk, Adobe, and DoorDash as advisors/investors.
- **Growth Signals**: Headcount of 30 employees (LinkedIn, Apr 2026) with +32.1% yearly growth; monthly job posting growth +66.7% year-over-year; trusted by leading engineering firms and state DOTs; launched Digital Surveyor 2 in March 2026; featured in Geo Week News and YC blog.

## Competitive Advantages
- **AI-native CAD workflow**: Unlike traditional manual drafting, DS2's AI "drafts with you" – learning from user edits to improve suggestions in real time, cutting manual drafting time by up to 96×.
- **Field-to-finish in one environment**: No need to switch between preprocessing, extraction, and CAD tools – all done in a single web-based platform.
- **Strong research roots**: Built on decades of research from Carnegie Mellon University's Robotics Institute, giving a deep technical moat in computer vision and geospatial ML.
- **Designed for surveyors**: Intuitive UI that lets domain experts (not just CAD specialists) be productive on day one.

## Strategic Focus
- **Scale GTM and engineering**: Active hiring across sales (Account Executive, Founding Marketer), engineering (ML Infrastructure Engineer, Perception Software Engineer, Head of Product Engineering), and operations (Solutions Consultant, QA Survey Technician).
- **Expand into new verticals**: Targeting electric/telecom utilities, data centers, and broader infrastructure beyond transportation.
- **Product evolution**: Continuously improving AI accuracy and automation, with a focus on trust and user control (as highlighted in the DS2 launch).

## Why Work Here
- **Culture**: Fast-paced, customer-obsessed, engineering-first environment. Values: "work fast, iterate with customer feedback, never compromise on excellence."
- **Remote/Hybrid Policy**: HQ in San Francisco; some roles are "Remote / Remote (US)" per YC job listings. Likely hybrid with in-office presence for SF-based roles.
- **Perks & Benefits**: Health, vision, dental insurance; paid parental leave; flexible time off; equity package for all full-time employees; company 401(k); relocation assistance; catered lunches & paid dinner; company & team events; dog-friendly office.
- **Engineering culture**: Deep technical challenges at the intersection of AI, geospatial, computer graphics, and infrastructure. Opportunity to work on hard problems that "unlock billions in value for customers."
