Senior Principal 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 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. 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. • 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.
