Responsibilities

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

Required

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

Preferred

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
