Job summary

Code Metal is seeking a Physics Engine Programmer to build the core C++ runtime for a next-generation wargaming platform. You will own engine structure, performance, and long-term health, while shaping an ECS architecture for massive simulation workloads.

You will implement data-oriented storage, scheduling, and interfaces for physics, AI, and environmental models. Ideal candidates ship real-time systems in commercial game or engine contexts, understand performance budgets, and lead

Qualifications

• Extensive professional C++ development experience in production software.
• Experience shipping a commercial game/engine.
• Ownership of foundational engine systems and runtime.
• Experience building/extending a physics engine or ECS.
• Strong knowledge of data-oriented design and memory layout.
• Ability to optimize for CPU, memory, latency budgets.

Responsibilities

• Architect and implement the core C++ runtime for a large-scale wargaming platform.
• Own engine structure, performance, and long-term health.
• Design and evolve an ECS architecture for many heterogeneous entities.
• Build data-oriented storage, lifecycle management, and scheduling.
• Define interfaces for physics, AI, sensors, and environmental models.
• Create stable extension points for model developers.
