Senior Software Engineer, Systems

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, slides and written products 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.

Our product is currently in broad use at 8 of the largest military headquarters in the world. 3 of the 4 biggest operational plans in the US are currently built with Onebrief. Last year, we achieved 100% gross retention and 158% net retention—our revenue grew 4x and reached double-digit millions. We are backed by Y Combinator (S21) and top-tier VCs, including Caffeinated Capital (Affirm, Docker, Notion, and more) and Human Capital (Anduril, Brex, Snowflake, and more), and have raised a total of $53M in venture capital. Our elite team combines the best of tech and military talent, including education and experience at Google, Twitter, Adobe, MIT, Harvard, Special Operations, TOPGUN, and more.

As a Software Engineer, you'll work in close collaboration with our product, design, and tech operations teams. You’ll help Onebrief build AI and integrations within other DoD systems, creating the best military plans inside highly classified environments. You'll be working end to end on our platform, with a primary focus on server side development, designing and managing complex systems for our customers while working alongside our customers in SCIFs. Because of the onsite needs (80% of the time) and client facing nature, you have a military background to help understand our customers and develop with the users in mind. We expect 25% of travel to clients sites and SCIFs, so active security clearance is not required at start but a condition to hire.
