About The Position

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. We're hiring Staff Software Engineers to take on some of the most challenging and meaningful full-stack problems at Onebrief; the kind that sit at the intersection of system design, product complexity, and real-world stakes. Think: real-time collaboration infra, interactive planning UIs, and high-trust workflows that operate under real constraints. This is a senior IC role with broad surface area. Expect to own big bets, shaping direction, unblock teams, and raising the bar for how we build. You’ll partner tightly with PM, Design, and your fellow engineers. Your work will ripple across teams via reusable patterns, thoughtful abstractions, and crisp communication.
