Senior Principal Software Engineer, Modeling & Simulation

New Yesterday

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. 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.
