About Onebrief
Onebrief builds collaboration and AI-powered workflow software for military planning and operational coordination.
Military planning is complex by nature, requiring teams to coordinate information, people, and decisions across systems and locations. Onebrief brings planning, collaboration, simulation, and AI into one connected environment, helping teams test strategies, adapt to changing conditions, and make decisions with greater clarity when the stakes are real.
We are a distributed team of builders from military, operational, and technology backgrounds who care deeply about improving how important work gets done. Some team members work remotely, while others work directly alongside customers in operational environments around the world.
Founded in 2019, Onebrief is backed by leading investors including General Catalyst, Battery Ventures, Insight Partners, Sapphire Ventures, and Human Capital. Valued at more than $2 billion, we continue to invest in product innovation, AI capabilities, and team growth.
Security Clearance, Location, and Onsite Notice:
This role requires regularly working on-site at customer locations in Arlington, VA.
If you are not currently within commuting distance, you must be willing to relocate (note that Onebrief will provide relocation assistance).
Active Secret Clearance required; SCI eligibility is a plus.
About The Role
We are hiring a Site Reliability Engineer to join our Infrastructure & Security team. You’ll work closely with fellow SREs, security, and customer success.
You will be the first line of support for our mission critical deployments, and responsible for ensuring best-in-class service quality and issue resolution. You will work in both on-premise DoD environments and AWS cloud environments. Your lessons from the field will shape how our team works, from policy to implementation.
In addition to working at the customer, you will contribute directly to solutions that increase stability, performance, and security of our deployments, and improve the overall experience of deploying and managing Onebrief on premise.
About You
You care deeply about reliability and treat it as a core feature of any application or platform, with a bias toward “reliability over novelty.” You think about infrastructure and operability as products to be automated, well-documented, and continuously improved, and you aim to leave systems easier to operate than you found them.
