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 programmingWhy Code Metal? Mission with impact: your work shapes the digital battlefield models that influence real-world acquisitionVelocity: small teams, rapid iteration cycles, and the mandate to ship Ownership: no passengers, everyone pushes code that hits productionRequirementsMust-have credentialsBachelor's degree (or equivalent experience) in applied math, scientific computing, physics, or a related fieldProven expertise in multi-threaded C++ for high-performance applicationsHands-on experience with large-scale, physics-based simulations.
