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

Begin to influence work outside of your direct team, solving complex problems impacting performance, features, and product design
Support and unblock peers through async reviews, pairing, and mentorship
Work in an async-first way, aligning clearly on scope, tradeoffs, and outcomes
Build across the stack, using TypeScript/React/Node with PostgreSQL, Redis, and Kubernetes under the hood

6+ years of experience as a Software Engineer, including owning meaningful product or platform surfaces
Experience collaborating across teams to deliver elegant, strategic solutions to defined problems
A comprehensive understanding of the current state of web technology and best practices
A track record of shipping in B2B SaaS or similarly demanding domains
Clear, context-rich communication across PRs, RFCs, and collaborative docs
Comfort navigating ambiguity and low-process, async environments
Hands-on experience improving team velocity via tooling or process improvements
