About Onebrief

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.

Why This Role Exists

You stay current on product updates, translating new releases into practical impact for the specific workflows your customer relies on. You act as the primary line of communication between the customer and Onebrief — as the product evolves, you deliver ongoing, role-specific training to ensure users adopt new capabilities rather than getting stuck on outdated workflows.

• You hold a current Top Secret clearance with eligibility for SCI and have the ability to access DOD facilities and installations.

Preferred Qualifications

• You’re technically adept. You don’t need to code, but you do need to be savvy. Can you become a power user of our product and talk engineering with the customer?

• Customers trust you. You demonstrate strong interpersonal skills, develop rapport, align diverse perspectives, and communicate with clarity and influence.

• You’re intense about our mission . It’s a core part of who you are
