Senior Software Engineer, Modeling & Simulation

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

• 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)
