Principal Frontend Engineer

The role

You will architect, build, and scale real-time geospatial interfaces used to command autonomous systems. You will work with the Head of Frontend to design map layer systems and implement high-frequency real-time data patterns in React applications.

What you will do

• Bring production-tested patterns for high-frequency real-time data in React applications
• Guide the design and evolution of the map layer system
• Work with the Head of Frontend and senior engineers on scaling decisions
• Implement code and perform reviews to ensure scalability
• Identify performance and architectural risks early
• Communicate technical decisions through design reviews and technical proposals
• Mentor senior engineers in real-time and geospatial engineering

Required qualifications

• 10+ years of frontend engineering experience, including significant experience operating at Staff, Principal, or equivalent technical scope
• Deep production experience building and scaling high-volume, real-time applications
• Expert-level experience with React and TypeScript
• Deep experience building map-based geospatial applications using MapLibre, Mapbox GL, Deck.gl, or equivalent technologies
• Demonstrated experience optimizing large and dynamic geospatial feature sets
• Hands-on experience scaling a real-time application through significant growth in tracked entities, update frequency, or data volume
• Experience with multiple real-time communication technologies such as WebSockets, MQTT, gRPC-web, SSE, or similar protocols
• Deep browser performance expertise across rendering, memory, CPU, networking, and GPU bottlenecks
• Experience designing client-side data architectures using workers, batching, caching, state boundaries, and other techniques
• Experience designing applications for degraded or intermittent connectivity
• Strong software architecture and systems-design fundamentals
• Demonstrated ability to make sound technical tradeoffs and sequence architectural changes within a production system

Nice to have

• Experience taking an internal operational tool to a multi-tenant product
• Data visualization depth (D3, custom charting, large-dataset rendering)
• 3D and WebGL: three.js, custom shaders, terrain, or vertically distributed asset rendering
• Experience with defense, aerospace, robotics, or other operationally critical systems

Benefits

• 100% Employer paid Health Insurance
• Dental and Vision Insurance for you and your families
• Life Insurance (Employer Paid)
• Ability to participate in the companies 401k program (Matching)
• Unlimited PTO policy with an enforced 2 week minimum
