We build autonomous heavy equipment (bulldozers, loaders, excavators), enabling fleets powered by AI to operate continuously, safely, and efficiently in the world’s harshest environments. Built by leading minds from industries like mining, construction, Waymo, SpaceX, Google, and Tesla, AIM’s platform supports production mines, large-scale infrastructure projects, and defense operations. We are backed by top-tier investors including General Catalyst, Khosla Ventures, Elad Gil, Human Capital, Ironspring Ventures, Mantis, and DCVC.

About

the Role The user interface is where humans interact with autonomy. As a Senior React Developer, you'll design and build robust web applications powering AIM’s autonomous fleet: a safety-critical Operator UI, a multi-tenant customer portal, and the design system underpinning both. You write clean, maintainable TypeScript and React, and bring equal rigor to UI correctness, safety, reliability, and user experience. You understand the difference between a UI that looks correct and one that is truly reliable—even under adverse conditions like bright sunlight or gloved operation on a worksite. You'll thrive in a team that prizes clarity, customer focus, and engineering excellence.

Responsibilities Architect and build a robust design system, including setting the direction for components, accessibility, theming, versioning, and migration tooling Own the developer experience for all engineers leveraging the design system Develop the Operator UI, including: Implementing live 3D scenes using Three.js, React Three Fiber, and Drei (rendering point clouds, geofences, machine overlays) Designing state machines (XState), validation, and observability for safety-critical flows Building teleop controls and integrating live video streaming Shape the administration portal as a true SaaS product, focusing on: Multi-tenant authorization, internationalization, and real-time data architecture Designing customer-facing experiences meeting B2B software standards Deliver production-ready, high-quality TypeScript using modern frontend engineering best practices Lead code reviews, design reviews, and architectural discussions Collaborate with field deployment engineers to gather real-world feedback and improve the codebase

Qualifications Basic

Qualifications Bachelor’s degree in Computer Science, Computer Engineering, Design, HCI, or equivalent hands-on experience 5+ years of professional software engineering experience delivering production frontend systems Deep expertise with TypeScript and React (modern patterns like hooks, suspense, and concurrent rendering) Familiarity with frontend tools: Vite, npm/pnpm workspaces, Storybook, Vitest, Cypress, Testing Library Strong debugging skills (browser devtools, logs, telemetry, tracing) Proven track record of delivering high-quality software individually and across teams Preferred

Qualifications Experience with 3D web graphics: Three.js, React Three Fiber, WebGL, or point cloud rendering Experience with real-time data and binary serialization (Protocol Buffers, gRPC-web, WebSockets) Exposure to safety-critical or industrial UI in sectors like robotics, automotive, aerospace, medical, or defense Experience with state machines (XState), TanStack Router/Query, Zustand, Tailwind CSS, Floating UI, or multi-tenant SaaS authorization (ReBAC/ABAC) What We Offer High-impact ownership across our frontend stack and global deployments Collaboration with world-class engineers in software, autonomy, hardware, and robotics Competitive

About AIM Intelligent Machines

AIM = AI Autonomy Platform for Heavy Machinery

Scalable earthmoving is not optional. It’s required for our civilization to flourish.

Critical materials like copper, iron ore, and lithium are in short supply and dangerous to mine. One billion people live less than 10 meters above rising oceans, 1 in 6 people live in areas with significant wildfire risk, 43% of critical infrastructure is in disrepair and will cost $2.6 trillion to fix, and pollution from the Manhattan Project is still being cleaned up with a $300 billion invoice. Food production must increase 60% to feed the 2050 population, and it will take 757 years to remove mines in Ukraine with traditional methods. What do these problems have in common? One, our civilization does not have a feasible way to address challenges of this magnitude. Two, earthmoving is a key part of the solution.

Our commercially deployed autonomy product runs a wide range of existing earthmoving machinery (new, older, large, small, any brand). As a result, our customers run their operations at maximum throughput and safety. The AIM platform unlocks tremendous value across mining, construction, and defense.

AIM has been built by world-class engineers who developed cutting-edge products at Google, Waymo, Tesla, and SpaceX. We bring deep expertise in autonomy, robotics, hardware, and advanced AI deployed at scale.
