Role
Who you are
- 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
- 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
- Due to federal contract requirements, U.S. Citizenship is mandatory for this position
What the job involves
- Battle Road Digital, part of Onebrief, applies state-of-the-art innovations and experience from the video game industry to build the future of simulations, modeling, and operations with AtomEngine – our proprietary cloud-based game engine that’s making the world playable
- 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
- 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
Our take
Onebrief is transforming military planning with its software platform, which simplifies and speeds up operational tasks for US military headquarters worldwide. The platform enhances decision-making and streamlines complex planning, supporting various missions from defense to humanitarian aid.
The company has continuously updated its offering, for example by launching an API for better integration with other military tools, and developing offline access for remote use. It has also added AI features as part of continued innovation to meet the evolving needs of military users.
Onebrief has secured substantial funding which has allowed it to grow significantly. The latest round, secured in early 2026, will support rapid scaling and comes alongside the company's acquisition of Battle Road Digital, a leading defense innovation company applying gaming technology to defense and national security challenges.
