Staff Software Engineer, Full-stack

CONSEQUENTIAL WORK. DEDICATED PEOPLE.

ABOUT ONEBRIEF

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

Today, many critical planning workflows still rely on fragmented systems, static documents, and disconnected tools that make collaboration and decision-making unnecessarily difficult. Onebrief brings modern software, AI, and real-time collaboration into those environments, helping teams operate with greater clarity, coordination, and adaptability in situations where decisions carry real-world consequences.

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.
