Simulation Content Creator

Onebrief builds collaboration and AI-powered workflow software for military planning and operational coordination.

Military planning is complex by nature, requiring teams to coordinate information, people, and decisions across systems and locations. Onebrief brings planning, collaboration, simulation, and AI into one connected environment, helping teams test strategies, adapt to changing conditions, and make decisions with greater clarity when the stakes are real.

We are a distributed team of builders from military, operational, and technology backgrounds who care deeply about improving how important work gets done. Some team members work remotely, while others work directly alongside customers in operational environments around the world.

Founded in 2019, Onebrief is backed by leading investors including General Catalyst, Battery Ventures, Insight Partners, Sapphire Ventures, and Human Capital. Valued at more than $2 billion, we continue to invest in product innovation, AI capabilities, and team growth.

Through AtomEngine, Onebrief leverages advanced game engine concepts to power AtomEngine—our proprietary cloud-based engine designed to make complex operational environments and military modeling dynamic, interactive, and playable.

We are hiring a Simulation Content Creator to bridge product design and real-world domain data. In this role, you will help create high-fidelity, functional entities and scenarios that allow planners and wargamers to model critical operations with accuracy and depth.

This is a position 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.

AtomEngine is Onebrief's proprietary cloud-based simulation and modeling engine that powers large-scale analysis and continuous wargaming. By leveraging advanced game engine concepts, AtomEngine transforms complex operational environments and military modeling into dynamic, interactive, and playable experiences where users test strategy against realistic constraints.

You will partner closely with our feature design and product teams to expand and refine the AtomEngine simulation ecosystem. Your core responsibilities include:

• 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

• 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

• 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

This role will evolve as priorities change, but the outcomes below reflect what success typically looks like in the first six months. A successful Simulation Content Creator will:

• 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
