Onebrief is collaboration and AI-powered workflow software designed specifically for military staffs. Onebrief makes the staff as a whole superhuman — faster, smarter, and more efficient — to ultimately support stronger decision-making. Backed by Battery, General Catalyst and Insight.
About the role
Military planners need to understand what a simulation can tell them, where its assumptions hold, and where they do not. At Onebrief, you will own the models and data that make those answers defensible in AtomEngine, our cloud-based simulation engine for military planning.
What they're looking for
- Experience applying modeling and simulation, systems engineering, operations research, or test and evaluation to complex systems. You can assess whether a model is credible for its intended use and explain why
- Quantitative judgment: you can evaluate performance formulas, identify weak assumptions, and decide when to use an existing approach or develop a new one. You can make defensible calls when evidence is incomplete or conflicting
- Ownership of complex technical work. You can translate competing needs into priorities, establish repeatable processes, and keep a large body of work organized, current, and traceable
- Practical experience directing AI agents through research or analytical tasks, including clear instructions, review checkpoints, and error correction. You can evaluate their output against source evidence
- Clear technical communication and the confidence to work through disagreements with customers and SMEs. You can turn your reasoning into standards and documentation others can follow
- An investigative approach to simulation and wargaming: you actively look for where a model breaks and use what you learn to improve it
