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 a hands-on leader who can architect and build an 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 the core codebase 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

• Master's degree (or equivalent) 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 higher)
  
  

Bonus points

• PhD (or equivalent depth) in applied math, scientific computing, physics, or similar
• GPU compute chops—OpenCL, CUDA, etc...
• Data oriented framework design experience like ECS
• Prior work running physics simulations in distributed cloud environments.
• TS/SCI clearance
