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 RoleOnebrief's infrastructure team owns the platform that delivers our software to military staffs. Our charter spans Kubernetes clusters in commercial and government cloud, application streaming for thin-client users on classified networks, a unified artifact pipeline that signs and ships the same builds to every environment we operate, and air-gapped appliances at forward sites.
We're hiring an Infrastructure Engineer who builds security into the systems they operate rather than treating it as a separate workstream. You'll architect, build, and run the platform end to end. This includes RFCs, PRDs, and reviewing and writing production code alongside Product and Engineering teammates. The work cuts across cloud-native deployments, edge appliances, data platforms, and the application streaming layer that puts Onebrief on classified environments. You'll partner with Governance, Risk, and Compliance (GRC) and mission owners on STIGs, CVE remediation, audit prep, and the controls work that lets us operate in environments such as IL5, IL6, and JWICS.
Success means a platform that stays up under real operational load, ships trusted artifacts to every profile we run, and passes audits without fire drills.
People by-name request you because you bias towards action. You are a problem-solver by nature who genuinely cares about the mission and the outcome. You operate without hand-holding. You read a problem, weigh tradeoffs, and move. Sometimes the tradeoffs have harsh consequences that you pay for later, but you are resilient and adapt. When the work crosses into expertise you don't have, you dig into the problem, pull in the right teammates, apply their feedback, and continue.
Design, develop, test, iterate, and deploy secure production systems across cloud-native and edge appliance deployments
Embed with cross-functional teams and advise on infrastructure, security, and deployment best practices that hold up in production
Own end-to-end infrastructure outcomes for one or more critical programs or priority infrastructure initiatives
Harden the artifact pipeline so the same signed builds run in cloud, single-tenant high-side, and air-gapped appliance deployments
You'll do well in this role if you bring:
8+ years operating production infrastructure in DevOps/DevSecOps, Platform, SRE, Cloud, or Infrastructure role
Full-stack engineering experience when necessary, e.g., production experience designing, building, and operating services in a modern backend language (e.g., Go, Python, Rust, TypeScript)
Deep production Kubernetes experience: operators, networking, storage, multi-cluster operations, and a feel for what breaks at scale
Expertise with major cloud providers (e.g., Amazon AWS, Microsoft Azure), with strong instincts for designing across providers and profiles
Strong application and infrastructure security fundamentals: identity, network segmentation, secrets management, common vulnerability classes, and sound security judgment under ambiguity
Demonstrated ability to build working solutions from scratch, connect disparate applications together, and jump into existing code bases to add value
Experience packaging and shipping workloads into disconnected or air-gapped environments
Demonstrated leadership/mentorship experience
Ability to obtain a SECRET clearance
Nice to have qualifications:
Active US SECRET or TOP SECRET security clearance
Government cloud expertise (AWS GovCloud, Azure Government)
FedRAMP, IL4/IL5, IL6, or JWICS environment exposure
Audit experience (FedRAMP, SOC 2, or equivalent)
Big data and distributed data experience
Prior experience supporting defense, intelligence, or other regulated industries
