Job Description

Frontend Engineer (UI/UX)

We're looking for a Frontend Engineer to design and build modern, responsive web applications for Command & Control (C2) and collaborative autonomy platforms. You'll create intuitive, high-performance interfaces for mission management, autonomous system coordination, mapping, and real-time decision support while helping shape the future of autonomy at scale.

What It's Like to Work Here

We're a fast-paced engineering team that believes the best products are built by testing early, iterating often, and shipping quickly. Engineers have a high degree of ownership and work across the entire product lifecycle—from idea to deployment.

Field testing is a core part of how we build. We prefer to be on the water daily, validating new features, observing operators, and seeing our systems perform in real-world conditions. That direct connection between engineering and field operations helps us make better design decisions, move faster, and build products that solve real problems.

What You'll Work On

  • Design and build modern web applications using React, Redux, and TypeScript.
  • Shape the user experience for next-generation Command & Control (C2) and collaborative autonomy platforms.
  • Build intuitive interfaces for planning, monitoring, and coordinating teams of autonomous systems.
  • Help evolve collaborative autonomy from smaller coordinated teams to large, heterogeneous fleets operating across domains.
  • Design user experiences that enable operators to confidently command, monitor, and manage increasingly complex autonomous missions at scale.
  • Build interactive mapping, mission planning, and situational awareness experiences using Mapbox, MapLibre, and real-time geospatial data.
  • Create real-time dashboards and operational visualizations powered by live telemetry, WebSockets, and cloud services.
  • Build scalable frontend architecture that supports increasingly complex missions, larger deployments, and new autonomous capabilities.
  • Work closely with autonomy, robotics, and backend engineers to rapidly prototype, test, and deploy new capabilities.

Requirements

  • 3+ years of experience building production web applications with React.
  • Strong experience with Redux (or similar state management libraries).
  • Experience with Mapbox, MapLibre, or other interactive mapping frameworks.
  • Strong understanding of TypeScript, modern JavaScript, HTML, and CSS.
  • Strong UI/UX skills with an eye for clean, intuitive, and visually polished interfaces.
  • Ability to simplify complex operational workflows into intuitive user experiences.
  • Experience consuming REST APIs, WebSockets, connectRPC, or gRPC services.
  • Experience building responsive, production-quality web applications.
  • Familiarity with Git, CI/CD, and Agile development practices.

Nice to Have

  • Experience developing Command & Control (C2), collaborative autonomy, mission planning, robotics, or autonomous systems software.
  • Experience with mapping, telemetry, real-time operational visualization, or fleet management systems.
  • Familiarity with Figma, design systems, or component libraries.
  • Experience with Deck.gl, D3.js, or other visualization libraries.
  • Working knowledge of Go and AWS.
  • Experience with Kubernetes, AWS Lambda, or distributed systems.
  • Knowledge of WebRTC or SRT streaming.
