havocai - Principal Frontend Engineer
Requirements
• 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, including a first-principles understanding of React’s rendering model and frontend performance. • Deep experience building map-based geospatial applications using MapLibre, Mapbox GL, Deck.gl http://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 for isolating high-frequency workloads. • Experience designing applications for degraded or intermittent connectivity, including reconnection and state reconciliation. • Strong software architecture and systems-design fundamentals. • Demonstrated ability to make sound technical tradeoffs and sequence architectural changes within a production system. • Strong written and verbal communication skills with the ability to influence technical direction without relying on formal authority. • High ownership and comfort operating in a fast-moving, ambiguous engineering environment. • 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 • WHAT SUCCESS LOOKS LIKE
Responsibilities
• FRONTEND ARCHITECTURE & REAL-TIME SYSTEMS • GEOSPATIAL ENGINEERING • Bring proven, production-tested patterns for high-frequency real-time data in React applications: transport-to-render design, update throttling, and keeping telemetry off the render path • Guide the design and evolution of the map layer system: layer lifecycle, interaction state, feature identity, and rendering performance on large feature sets • Work with the Head of Frontend and senior engineers on scaling decisions, contributing the perspective of someone who has made them before • Build alongside the team: implement the hard parts, set the example in code, and review with an eye toward what will hold up at scale • Identify performance and architectural risks early, before they become incidents • Communicate technical decisions clearly through design reviews, technical proposals, and code, building alignment without creating unnecessary process • Mentor senior engineers in real-time and geospatial engineering • Helped establish a frontend architecture capable of supporting significantly greater numbers of autonomous assets, telemetry streams, and real-time updates. • Improved the performance, responsiveness, and reliability of HavocAI’s geospatial interfaces. • Established scalable patterns for real-time data ingestion, state management, geospatial rendering, and degraded-connectivity scenarios. • Identified and addressed architectural risks before they became constraints on product or platform growth. • Raised the technical bar across the frontend organization through hands-on engineering, design reviews, architecture, and mentorship.
