Physics Programmer, C++ (Modeling & Simulation)

Remote (Remote)fulltimemidAdded 6 days ago

About this role

Code Metal seeks a Physics Programmer to architect and build the core C++ simulation runtime for a next-generation wargaming platform used by Department of Defense decision-making. You'll design entity-component systems, optimize performance under strict budgets, and integrate physics and behavior models into a large-scale interactive simulation engine.

What you'll do

  • Architect and implement the core C++ runtime for an interactive wargaming platform with hard performance constraints
  • Design and evolve entity-component-system architecture for representing large numbers of heterogeneous simulation entities
  • Build data-oriented component storage, entity lifecycle management, system queries, and dependency-aware scheduling
  • Develop multithreaded and task-based execution systems to safely parallelize simulation workloads
  • Profile and optimize memory layout, cache locality, and CPU utilization against explicit performance budgets
  • Lead architecture design reviews, mentor other programmers, and establish standards for C++ performance engineering

What they're looking for

  • C++ (8+ years professional experience)
  • Entity-component system (ECS) architecture design
  • Real-time performance optimization and profiling
  • Multithreading and task-based concurrency
  • Data-oriented design and memory management
  • Simulation architecture and deterministic execution
  • Game engine or real-time systems development
  • Spatial indexing and physics integration
