Simulation Content Creator

Onebrief builds collaboration and AI-powered workflow software for military planning and operational coordination. We help teams operate with greater clarity, coordination, and adaptability in situations where decisions carry real-world consequences by bringing modern software, AI, and real-time collaboration into fragmented, static, and disconnected planning environments.

We are a distributed team of builders from military, operational, and technology backgrounds. Founded in 2019 and backed by leading investors including General Catalyst, Battery Ventures, Insight Partners, Sapphire Ventures, and Human Capital, Onebrief is valued at over $2 billion and continues to invest in product innovation, AI capabilities, and team growth.

About the role

Through AtomEngine, Onebrief leverages advanced game engine concepts to power our proprietary cloud-based engine designed to make complex operational environments and military modeling dynamic, interactive, and playable. As a Simulation Content Creator, you will bridge product design and real-world domain data by creating high-fidelity, functional entities and scenarios that allow planners and wargamers to model critical operations with accuracy and depth.

This role is ideal for a thoughtful builder who thrives on detail, historical or technical research, and system design. You will turn complex real-world platform performance into intuitive, simulation-ready scenarios that directly drive better decision-making for our users.

Responsibilities

• Gather and analyze accurate performance data for global military platforms across diverse operational domains
• Build, configure, and maintain functional, simulation-ready entities using the AtomEngine editor
• Test entities against one another to tune, balance, and verify real-world behavior and interactions
• Design and publish challenging gameplay scenarios and wargaming environments that reflect realistic tactical and operational constraints
• Collaborate with product design to identify tool bugs, troubleshoot configuration issues, and improve authoring workflows
• Maintain clear, accessible documentation for the growing entity catalog and scenario library

Requirements

• Strong analytical skills with a demonstrated ability to independently troubleshoot data and configuration issues
• Concise and effective written and spoken communication skills
• Deep curiosity for understanding how complex systems, mechanical platforms, or operational dynamics function in detail
• Experience using game modding tools, level editors, or proprietary game engines in either a professional or personal project setting
• U.S. Citizenship, required due to federal contract requirements

Preferred Qualifications

• Familiarity with standard game development workflows, including version control and bug tracking systems
• Experience researching, synthesizing, or organizing technical reference material and platform performance data

Indicators of Success

This role will evolve as priorities change, but the following outcomes reflect what success typically looks like in the first six months:

• Establish a reliable rhythm for authoring, testing, and balancing new entities within the AtomEngine catalog
• Build authentic, challenging simulation scenarios that effectively exercise engine capabilities and support user wargaming objectives
• Serve as a key feedback loop for the engineering team by identifying editor friction points and logging actionable bug reports
• Produce organized documentation that allows internal team members to easily navigate and utilize the expanding entity library
