Principal Frontend Engineer

OverviewRole: Principal Front-End EngineerLocation/Time zones: US-based (East Coast preferred; Mountain works).Work setup: Remote (high-ownership, small team).Mission: Lead the front-end technical direction for a geospatial product used in a fragile/mission-sensitive deployment environment.ResponsibilitiesSet 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.What we're looking for8+ 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.Nice-to-havesGIS / 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.Why this role / why nowAs the product grows, we want a principal-level front-end leader who can keep the system coherent while still shipping
