Simulation Engineer - 1099 Contract

Rocket Science Group • Albany, NY

2d

About The Position

Atomic Theory, part of the Rocket Science Group, is seeking a C++ / Simulation Engineer to drive the performance, architecture, and migration efforts of its simulation projects. The role involves implementing gameplay features and Flecs ECS patterns, and optimizing simulation performance for large-scale, multi-server environments. The engineer will develop core simulation logic supporting partners’ interactive experiences. The position is a 1099 contract through April 2027, with an ASAP start requested. It can be remote, with the option to work in a hybrid setup at the Albany, NY office.

Requirements

• Proficiency with Entity Component System architectures, preferably Flecs.
• Solid understanding of linear algebra, physics, and simulation mathematics.
• 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 ability to collaborate with engineers, designers, producers, and project leads.
• Proactive and thoughtful approach to identifying, diagnosing, and resolving technical challenges.
• Genuine enthusiasm for games and desire to help create engaging, high-quality player experiences.
• Curiosity and eagerness to learn new technologies, engines, and practices.

Nice To Haves

• 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.
• Experience working with internal or external partners to gather feedback, provide technical input, and solve problems collaboratively.

Responsibilities

• Identify and migrate under-performing GDScript systems to C++ to improve performance and maintainability.
• Design and implement simulation logic using the Flecs ECS framework, with attention to data locality and scalability.
• Profile simulation workloads, identify bottlenecks, and apply multithreading techniques to optimize frame time.
• Develop serialization and state replication systems to support distributed simulation.
• Collaborate with the team to break down complex simulation requirements and deliver practical, high-performance solutions.
