Familiarity with tools like Docker, Git, asynchronous programming, and testing frameworks such as Pytest is often required. Excellent problem-solving skills, adaptability, and clear communication are valuable soft skills in this role. These competencies ensure robust API development, seamless collaboration, and the delivery of high-quality software solutions in agile environments.

What are the typical daily responsibilities of a FastAPI Developer?

As a FastAPI Developer, your daily tasks typically include designing and implementing RESTful APIs, writing efficient and maintainable code, and performing thorough testing to ensure reliability and performance. You may also collaborate closely with frontend developers, DevOps engineers, and QA teams to integrate new features and troubleshoot issues. Regular code reviews, documentation, and participation in agile development meetings are common parts of the workday. This collaborative and dynamic environment allows you to make a direct impact on the product while growing your skills through hands-on problem-solving and teamwork.

Job description

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.
  • Proven expertise in ZeroMQ, NATS, Kafka, or similar high-throughput messaging systems.
  • Hands-on with Postgres/PostGIS and Redis in performance-critical workloads.
  • Cloud-native chops-Docker, Kubernetes, and one major provider (AWS, GCP, Azure, or GovCloud).
  • Active Secret clearance or eligibility to obtain one.
Bonus points
  • C++ or Rust skills for bridging high-performance simulation modules.
  • Hardened services for FedRAMP / STIG compliance.
  • Observability mindset-Prometheus, Grafana, OpenTelemetry.
  • 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.
