# Senior Backend Platform Engineer, Distributed Systems

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

**Workplace:** hybrid

## 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.
