Simulation Engineer - 1099 Contract

Rocket Science Group’s Atomic Theory team is seeking a C++ / Simulation Engineer to drive the performance, architecture, and migration of simulation projects. The role focuses on implementing gameplay and ECS features, optimizing simulation workloads, and developing serialization and state replication for distributed simulations.

Responsibilities:

• C++ Migration: Identify and migrate under-performing GDScript systems to C++ for improved performance and maintainability
• ECS Implementation: Design and implement simulation logic using the Flecs ECS framework, ensuring efficient data locality and scalability
• Performance Optimization: Profile simulation workloads, identify bottlenecks, and apply multithreading techniques to optimize frame time
• Serialization & State: Develop robust serialization and state replication systems for distributed simulation support
• Technical Design: Collaborate with the team to break down complex simulation requirements and deliver practical, high-performance solutions

Requirements:

• Proficiency with Entity Component System architectures, preferably with Flecs
• Solid understanding of linear algebra, physics, and simulation mathematics
• A commitment to writing clean, testable, and efficient code
• Ability to debug complex state issues and optimize performance-critical code paths
• Comfort working across different systems and disciplines within game development, with a generalist mindset
• Strong communication skills and the ability to work collaboratively with engineers, designers, producers, and project leads
• A proactive and thoughtful approach to identifying, diagnosing, and resolving technical challenges
• A genuine enthusiasm for games and a desire to help create engaging, high-quality experiences for players
• Curiosity and eagerness to learn new technologies, engines, and practices to remain adaptable and effective
• Familiarity with Godot/GDScript to assist in migration efforts
• Experience with networking, state synchronization, or multi-server architectures
• Advanced knowledge of concurrency, lock-free data structures, and parallel processing
• Experience supporting or mentoring less experienced developers as they build new skills
• Experience working with internal or external partners to gather feedback, provide technical input, and solve problems collaboratively
