Job Description:

Give decision-makers the clarity they need-exactly when they need it. At Code Metal, real-time physics sims, AI insights, and operator actions converge into massive data streams. As our Visualization & Frontend lead, you'll turn that firehose into elegant, high-impact experiences that guide multi-billion-dollar force-design choices driven through wargaming. We're looking for a hands-on architect who can shape a modular UI stack, tame dense geospatial and temporal data, and mentor a small, elite crew to ship polished products fast.What you'll do

• Architect a next-gen UI framework-design a component library and plugin system that lets internal teams (and future third-parties) extend visualizations without touching core code.
• Render data at scale-build responsive views that fuse live sim outputs, AI overlays, and historical datasets into one coherent, zoom-through timeline.
• Integrate cleanly-consume FastAPI/ZeroMQ endpoints from the backend and publish well-versioned client APIs for mission-planning tools and dashboards.
• Iterate with stakeholders and UX design Leads-relentlsly optimize experience driven by performance and feedback from Airforce wargamers and UX leads.
• Lead by example-drive UI/UX best practices, code reviews, design critique, and automated testing; help teammates grow into force multipliers.
• Ship continuously-own the CI/CD pipeline for web and desktop targets, with an eye toward DoD accreditation and cross-domain distribution.Why Code Metal?
  • Mission with impact: your visuals steer the conversations that shape tomorrow's force.
  • Velocity: tight loops, tiny teams-design in the morning, deploy by evening.
  • Ownership: no spectators-every engineer ships code that matters.Must-have credentials
    • 6+ years building and deploying data-rich, production-grade web applications.
    • Mastery of modern TypeScript/JavaScript frameworks and state-management patterns.
    • Proven record designing modular, extensible frontends that multiple teams can evolve in parallel.
    • Deep experience visualizing large datasets (time-series, geospatial, graph) in real time.
    • Strong grasp of secure, maintainable build and packaging workflows.
    • Active Secret clearance (or the ability to obtain quickly).Bonus points
      • WebGL / WebGPU, deck.gl, Cesium, or other high-performance rendering libraries.
      • Cross-platform desktop packaging (Electron, Tauri, Progressive Web Apps).
      • Familiarity with human-factors design for mission-critical environments.
      • TS/SCI clearance.
        • Health care plan with 100% premium coverage, including medical, dental, and vision.
        • 401k with 5% matching.
        • Paid Time Off (Uncapped Vacation, plus Sick & Public Holidays).
        • Flexible hybrid work arrangement.
        • Relocation assistance for qualifying employees.
