Job description

Job Summary:
AIM is transforming heavy machinery into AI-powered fleets, enhancing safety and performance in challenging environments. They are seeking a Senior Frontend Developer to design and build user interfaces that integrate human operators with autonomous systems, focusing on accessibility and performance.
Responsibilities:
• As a Senior Software Engineer with a UI focus, you will design and build the two web surfaces that put a human in the loop with AIM's autonomous fleet: the safety-critical Operator UI and the multi-tenant portal — and the shared design system that powers both.
• Set the architectural direction for component APIs, accessibility, theming, versioning, deprecation paths, and migration tooling.
• Own the developer experience of every engineer at AIM who builds on top of the design system.
• Drive the patterns that make it easy to ship high-quality, accessible UI by default.
• Architect and implement the live 3D scene with Three.js / React Three Fiber / Drei — point clouds, terrain meshes with BVH acceleration, geofence editing, cut/fill visualization, machine overlays.
• Design state machines (XState), validation, and observability for safety-critical UI flows.
• Build teleop controls and integrate live video streaming with the rigor those interfaces demand.
• Drive the architecture for multi-tenant authorization, internationalization (including RTL), and real-time data.
• Design customer-facing experiences that hold up to the standards of best-in-class B2B software.
• Write clean, testable, maintainable TypeScript using modern frontend engineering principles.
• Drive improvements in code quality, accessibility, performance, reliability, and observability.
• Lead code reviews, design reviews, and architectural discussions.
• Work with TPMs, design, autonomy, controls, hardware, and field ops to ensure your UI works reliably on real machines and at real customer sites.
• Partner with FDEs to understand field realities — sun glare, gloves, dropped networks — and incorporate operational truth back into the codebase.
• Drive root-cause analysis and elimination of recurring defects.
• Mentor junior and mid-level engineers.
• Improve developer experience, CI/CD, test frameworks (Vitest, Cypress, Testing Library, vitest-axe, MSW), and local development tooling.
• Help define SWE excellence and engineering mechanisms across the org.
Qualifications:
Required:
• 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 in TypeScript and React, including modern patterns (hooks, suspense, concurrent rendering).
• Experience with 3D web graphics: Three.js, React Three Fiber, Drei, WebGL, shaders, GLTF pipelines, BVH acceleration, or point-cloud rendering.
• Experience with real-time data and binary serialization: Protocol Buffers, gRPC-web, WebSockets, or high-frequency telemetry on the web.
• Experience with modern frontend tooling: Vite, npm workspaces (or pnpm/yarn workspaces), Storybook, modern testing stacks.
• Strong debugging skills using browser devtools, logs, telemetry, metrics, and tracing.
• Proven track record of delivering high-quality software independently and as part of cross-functional teams.
Preferred:
• Comfort working across the whole stack when needed.
• Experience with safety-critical or industrial UI: robotics, automotive, aerospace, medical, defense, energy — contexts where a bug has physical consequences.
• Experience with state machines (XState, statecharts) as a tool for safe UI flows, not as a buzzword.
• Experience with TanStack Router, TanStack Query, Zustand, Tailwind CSS v4, tailwind-variants, Floating UI, Mantine, or Visx.
• Experience with multi-tenant SaaS authorization (ReBAC/ABAC) and the UI patterns that make complex permissions comprehensible.
• Experience with frontend infrastructure: Docker, Kubernetes, CI/CD, micro-frontend architecture, OpenTelemetry, Sentry.
Company:
Scalable earthmoving is not optional. It’s required for our civilization to flourish. Founded in 2021, the company is headquartered in Bellevue, USA, with a team of 51-200 employees. The company is currently Growth Stage.
