About AIM

AIM Intelligent Machines is transforming the physical foundation of civilization—everything humanity depends on is mined, dug, or grown. 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
