Job description

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.
