[Hiring] Staff Simulation Data Modeler @Onebrief

Role Description

As a Staff Simulation Data Modeler at Onebrief, you own the ground truth that AtomEngine's entire simulation stands on. AtomEngine is our proprietary, cloud-based game engine that makes the world playable to solve real-world military problems. You'll build and defend that credibility by:

• Directing AI agents to research and construct entities at scale.
• Codifying the standards and formulas that make and keep the catalog accurate.
• Stress-testing your own assumptions in competitive wargames before a customer ever finds the gap.

You own the AtomEngine entity catalog end to end, focusing on:

• The sources, standards, parametric formulas, tooling, and test coverage that make them credible.
• Partnering closely with Customer Relations to prioritize what gets built next.
• Working with Engineering to automate testing.
• Collaborating with other Content Creators in competitive wargames designed to break your own assumptions.

Qualifications

• Strong research and analytical skills, with the judgment to make sound assumptions when source data is incomplete or conflicted.
• Demonstrated ability to direct AI agents productively, writing clear instructions, structuring review checkpoints, and catching agent errors.
• Comfort with quantitative modeling: ability to reason about and sanity-check formulas for weapon effects, fuel consumption, or survivability.
• Strong organizational skills: ability to build and maintain a catalog/tracking system spanning hundreds of items.
• Concise, effective written and verbal communication.
• A wargamer's mindset: care whether the simulation is right, not just whether it runs.
• Comfortable serving as the escalation point for contested technical calls.

Requirements

• Experience with game modding tools, editors, or simulation authoring environments (hobbyist or professional).
• Experience partnering with engineering on test automation or QA tooling.
• Familiarity with military doctrine, force structure, or platform performance data.
• Experience with version control and bug-tracking systems.
• Experience mentoring, training, or setting technical standards adopted by other analysts or contributors.
