Principal Frontend Engineer

The Role

• 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 Requirements

• 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).
• 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.
• Eligible to obtain and maintain an active U.S. Top Secret security clearance

Preferred Qualifications

• 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.
• Active U.S. security clearance (Secret or Top-Secret)
