Consequential Work. Dedicated People.

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

Our customers decide what to adopt and buy in settings we can’t always be in: exercises, headquarters, symposiums, and the working groups around them. Trust is built in person, and the right conversation at the right event can open an account or expand one. Onebrief is hiring a Field Marketing Manager to own that work.

In this role, you will turn the events, sponsorships, and account programs around our target accounts into a deliberate plan: which events matter, why, who we want to meet, and what happens afterward. You will work with Sales, Growth, and Customer Relations to prioritize named accounts, give sellers the materials they need, and make sure every conversation is followed up and tracked into the pipeline. You will also bring discipline to how we measure field activity, so we can invest more in what works and stop what doesn’t.

Our field presence is growing as we expand across the services, combatant commands, federal agencies, and commercial markets. You will help decide how we show up, with real ownership from the start. Defense experience helps, but what matters most is that you run events well, care about the customer, and can show us results.
