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.
