ABOUT ONEBRIEF Onebrief is collaboration and AI-powered workflow software designed specifically for military staffs. By transforming this work, Onebrief makes the staff as a whole superhuman - meaning faster, smarter, and more efficient. We take ownership, seek excellence, and play to win with the seriousness and camaraderie of an Olympic team. Onebrief operates as an all-remote company, though many of our employees work alongside our customers at military commands around the world. Founded in 2019 by a group of experienced planners, today, Onebrief’s team spans veterans from all forces and global organizations, and technologists from leading-edge software companies. We’ve raised $320m+ from top-tier investors, including Battery Ventures, General Catalyst, Sapphire Ventures, Insight Partners, and Human Capital, and today, Onebrief is valued at $2.15B. With this continued growth, Onebrief is able to make an impact where it matters most. ABOUT THE ROLE We're hiring a Staff Software Engineer to tackle some of the hardest technical problems at Onebrief — the kind that don't yet have a clear owner, a defined scope, or an obvious solution. We operate in a squad-based model: small, focused teams that form around outcomes and dissolve when the work is done. At the Staff level, you're not just effective within that model; you're one of the people who makes it work. You define technical direction before squads spin up, build the foundations that squads depend on, and bring coherence to decisions that would otherwise fragment across teams. Our platform spans a modern full stack: a React/TypeScript frontend, Node.js backend services, cloud-native infrastructure, and authentication and identity systems. You'll operate across all of it, not just as a contributor, but as someone who shapes how we build. ABOUT YOU You're energized by problems that are technically hard and organizationally complex. You don't wait for scope to be handed to you. You identify the highest-leverage work
