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. We’re seeking an experienced software developer who can own key parts of a larger extensible, cloud-distributed simulation environment, and inspire a small, high-conviction team by leading from the front.

What you’ll do

  • Design & implement a scalable, interactive physics simulation that runs seamlessly in cloud and on-prem clusters.
  • Own core functionality in modern C++ from multi-threaded performance tuning to continuous integration.
  • Collaborate with product & AI teams to embed verified, AI-generated algorithms directly into a developer SDK for extending the platform.
  • Prototype quickly, iterate faster: deliver usable capability to government end-users in weeks, not months.
  • Set the engineering bar—write clean code, document rigorously, and mentor teammates through code reviews and pair programming.

Why Code Metal?

  • Mission with impact: your work shapes the digital battlefield models that influence real-world acquisition.
  • Velocity: small teams, rapid iteration cycles, and the mandate to ship.
  • Ownership: no passengers, everyone pushes code that hits production.

Requirements

Must-have credentials

  • Bachelor's degree (or equivalent experience) in applied math, scientific computing, physics, or a related field.
  • Proven expertise in multi-threaded C++ for high-performance applications.
  • Hands-on experience with large-scale, physics-based simulations.
  • Active Secret clearance or eligibility to obtain one.

Bonus points

  • Master’s (or equivalent experience) in applied math, scientific computing, physics, or similar.
  • GPU compute chops—OpenCL, CUDA, or both.
  • Prior work running physics simulations in distributed cloud 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.
