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’re hiring an Executive Technology & Security Support Engineer to join Onebrief’s Technology & Security team. This is a high-impact role focused on keeping our executive team productive, protected, and confident in their technology—whether they’re at HQ, at home, or on the road. You’ll be the primary technology partner for executive leadership, working closely with IT, Cybersecurity, Engineering, Legal, and Compliance to support critical systems and reduce risk.
This role combines hands-on technical work with thoughtful security leadership and steady executive-facing support. You’ll own executive environments end to end, respond decisively in high-pressure moments, and proactively strengthen systems before issues arise. We’re looking for someone who operates with discretion, anticipates needs instinctively, and sees executive technology as a force multiplier for speed, trust, and focus.
About YouYou’re a steady presence in high-stakes situations. You work comfortably with senior leaders, make good decisions with imperfect information, and know when to move fast versus when to slow things down. You take ownership naturally, spot risks early, and follow issues through to resolution—especially when the work is sensitive or highly visible.
You’re technically strong and low-ego, able to explain complex issues clearly to non-technical audiences. You collaborate easily across teams, build trust through consistency, and care deeply about security and privacy without letting it get in the way of getting work done. You bring sound judgment, integrity, and a service mindset, knowing that how you show up matters just as much as the outcome.

Respond decisively under pressure
Lead rapid response to executive-impacting incidents, making clear tradeoffs, restoring service quickly, and coordinating closely with IT, Security, and Engineering teams.
Prevent problems before they surface
Proactively monitor executive environments, identify emerging risks, and address issues early—especially around travel, off-sites, and critical meetings.
Build trust through discretion and presence
Communicate calmly and clearly with executives, handle sensitive information with care, and serve as a dependable partner in moments that matter.
What We Look For5+ years of experience in IT support, systems administration, security, or a related role

Comfort operating in high-pressure, ambiguous environments with sound judgment

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

Your work directly addresses critical challenges that military planners and operators face daily. Every line of code and every design decision contributes to real-world outcomes.
The software was designed and built by a team of experienced planners - lending a nuanced perspective on the challenges our partners face. Our team embeds alongside users - from
the Pentagon to the Indo-Pacific - to build a platform that meets their unique needs.
