We are looking for a Game Engine Engineer who can operate comfortably across engine subsystems, reason about performance and scale, and conceive and develop thoughtful abstractions. The Game Engine Engineer implements, and evolves the core systems that power AtomEngine, our proprietary cloud-based game engine for large-scale simulation and modeling. Operating at the foundation of the platform, this role works across engine subsystems to ensure performance, scalability, and correctness as simulation complexity grows, developing and refining engine-level abstractions that support complex entities, behaviors, environments, and runtime systems. Successful candidates are systems-minded engineers comfortable working near the engine core, navigating ambiguity, and applying strong technical judgment to build clean, composable, and durable foundations rather than one-off solutions.
Job Responsibility:
Design, implement, and evolve core engine systems that power the AtomEngine runtime and editor
Design, build, and maintain complex, reusable engine systems and tools that form the foundation of AtomEngine
Analyze and lead efforts to improve performance, scalability, and stability across the engine and its dependent systems
Balance short-term delivery needs with long-term architectural clarity and maintainability
Collaborate closely with simulation engineers, tools developers, and AI engineers to integrate engine capabilities into higher-level systems
Contribute to code quality, technical standards, and best practices across the engine codebase
Identify technical risks and propose pragmatic solutions that preserve system integrity while maintaining development velocity
Requirements:
3+ years of software engineering experience, with a history of shipping games working across subject areas
Familiarity with popular game engines (Godot, Unity, Unreal)
Strong knowledge of standard engineering practices and a high bar for quality
U.S. Citizenship is mandatory for this position
