Senior ML/AI engineer Onebrief · United States (Remote)

About the job

Onebrief makes military planning seamless and represents a shift in paradigm for future military decisions. It is an all-in-one tool that supports both the creative and process-oriented aspects of military planning. In Onebrief, planners use maps, boards, diagrams, timelines, tables, slide decks and text documents to create their plans—all while sharing a common database. Everything stays in sync, in real time. Our approach has been refined and validated through hundreds of user experiments.

We’re post-revenue ($5M+ in ARR), and our customers include some of the most prestigious military commands around the world. We are backed by Y Combinator (S21) and top-tier VCs, including Caffeinated Capital (Affirm, Docker, Notion, and more). Our elite team combines the best of tech and military talent, including education and experience at Google, Facebook, Twitter, Adobe, MIT, Harvard, Rivian, Delta Force, TOPGUN, and more.

We have a big year ahead of us and can barely keep up with demand. This is an opportunity for you to join us with all the perks of an early employee.
