Simulation Engineer - 1099 Contract
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 engineer will implement gameplay features and Flecs ECS patterns, optimize simulation performance for large-scale, multi-server environments, and develop core simulation logic for partners’ interactive experiences. The role is remote, with the option to work in a hybrid setup from the company’s Albany, NY office. It is a 1099 contract position through April 2027, and candidates should be available to start as soon as possible. The hourly rate is typically $40.00–$70.00, with actual pay dependent on experience, skills, and qualifications.
Requirements
- Proficiency with Entity Component System architectures; Flecs is preferred.
- 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 systems and disciplines in 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 creating engaging, high-quality player experiences.
- Curiosity and eagerness to learn new technologies, engines, and practices.
- Availability to start as soon as possible.
Nice To Haves
- Familiarity with Godot/GDScript to assist with 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.
