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 RoleWe are hiring a Principal Infrastructure Engineer to lead the next evolution of Onebrief’s infrastructure. This role owns the long-term health, scalability, and technical direction of the platform. You will look beyond the current delivery cycle to anticipate the infrastructure needs of mission-critical applications operating across multiple air-gapped environments.
You are a strategic engineer who translates complex Department of War (DoW) constraints into a cohesive technical roadmap. Your work will enable product and engineering teams to deliver reliably across multiple classification levels with minimal friction.
About YouYou are a strategic planner who excels at technical roadmapping and can identify architectural gaps early, then build multi-quarter plans to address them before they become constraints. You think in systems, looking beyond individual tickets to understand and redesign the underlying infrastructure. When a pipeline fails, you focus on eliminating the class of failure rather than applying a temporary fix.
You take a pragmatic approach to technology decisions, knowing when to adopt new tools and when to invest further in proven systems. You value long-term maintainability and operational clarity over short-term optimizations. You lead by example, raising the technical bar through clear design documents, high-quality reviews, and mentorship on complex systems design.

What We Do
Before Onebrief, military planning and collaboration was slow, inefficient, and resource-intensive. Building slides with no version control as partners collaborated would have staffs spend weeks or months on a single product or document.
With Onebrief, these workflows are now simple and collaboration between large commands is efficient. Staff optimization is the key to building a more resilient, more effective military. Today Onebrief users report at least 2x time savings - and growing.
Onebrief is a first of its kind software for the military. While many others have tried to build a solution for this problem, Onebrief’s “card” structure for reusing data and enabling real time updates is what makes this possible. Core features and attributes that make this platform powerful include:
- Global Collaboration
- Real-Time Updates
- AI Automation
- Interoperability + Integrations
- Deployable across Secret and Top Secret Networks
