# Principal Software Engineer, Visualization & Frontend

> Code Metal · Boston, United States (Hybrid) · — · Posted 2025-05-08

**Workplace:** hybrid

## 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.

## Requirements

### 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.

## Benefits

-   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.
