Help redefine how the DoD makes multi-billion-dollar force-design decisions. In this role, you'll fuse physics-driven simulation, interactive computing, and verified AI code-generation to create next-generation wargaming platforms. If building ultra-low-latency APIs, taming high-volume geospatial data, and leading with clean, production-ready Python gets you fired up, let’s talk. What you’ll do Own the service layer—design, build, and scale FastAPI micro-services and lightning-fast ZeroMQ messaging pipelines running in Kubernetes and bare-metal clusters. Wrangle data at speed & scale—shape and query multi-TB Postgres/PostGIS datasets, orchestrate Redis for sub-millisecond state, and keep everything rock-solid under bursty load. Glue the stack together—expose crisp, well-versioned REST & WebSocket endpoints for the frontend crew and simulation kernel. Ship continuously—automate CI/CD, observability, and security hardening to DoD standards; push to prod with confidence. Lead by doing—drive code reviews, mentor teammates, and set the standard for test coverage and documentation. Why Code Metal? Mission with impact: your APIs become the nervous system of digital battlefields influencing multi-billion-dollar defense acquisitions. Velocity: tight-knit teams, weekly releases, zero bureaucratic drag. Ownership: no passengers—every engineer ships code that matters. Requirements Must-have credentials 4+ years building production backends in modern Python, with deep FastAPI (or equivalent async framework) experience.
