Job Description: Role
Who you are
8+ years building and scaling front-end systems; deep React + TypeScript expertise
Strong architectural judgment: you can balance “build fast” with “don’t paint us into a corner.”
Track record leading complex UI work (interactive, data-heavy apps; performance matters)
Experience working with design systems / component libraries (we’re using MUI; Tailwind is optional/uncertain)
Ability to operate in a fast-moving environment with minimal process overhead
Excellent communication: you can align teammates around patterns and decisions without slowing delivery
Desirable
GIS / geospatial domain experience (Cesium, mapping frameworks, geo interactions, coordinate systems, etc.)
Experience with visualization libraries (not required; product is more geospatial + UI workflows than pure D3)
Backend familiarity (API design, debugging cross-stack issues)
Prior work on simulation platforms, gaming-adjacent UI paradigms, or real-time systems

What the job involves
Role: Principal Front-End Engineer
Mission: Lead the front-end technical direction for a geospatial product used in a fragile/mission-sensitive deployment environment
You'll set front-end architecture and technical standards for a TypeScript/React application
Design scalable UI patterns for complex geospatial workflows (Cesium) and surrounding app features
Establish best practices for state management, component architecture, performance, testing, and maintainability
Partner with engineering leadership to plan, prioritize, and deliver high-impact product work
Mentor engineers through code reviews, architecture discussions, and practical implementation guidance
Drive execution: this role is hands-on and coding-heavy, not a “pure strategy” position
As the product grows, we want a principal-level front-end leader who can keep the system coherent while still shipping quickly—especially around geospatial UX and performance

Application process
Intro call (context + scope)
Architecture + deep-dive interview (with FE + leadership)
Practical exercise or portfolio/work-sample review focused on real product complexity
Final discussions / references

Our take

Worldwide spending on edge computing is growing at an astronomical rate. But, as organisations move to migrate their apps to the edge, the disparate nature of their approaches is making deployment difficult.
Code Metal is out to combat this with its modular, AI-powered workflows that support simpler and faster edge development. Its approach has been honed by previous work translating complex research algorithms for platform use, which it is now focusing on hardware apps for the edge.

The company has already made a splash in the space through some high-profile partnerships with the likes of L3Harris, a renowned American defence contractor. It has also raised substantial funding that it will use to expand its team, platform and launch within key industries.
