Job Specifications

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.
