Principal Software Engineer, Visualization & Frontend

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
