[Hiring] Infrastructure Engineer @Onebrief

Role Description

Onebrief'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
• 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
• Work across cloud-native deployments, edge appliances, data platforms, and the application streaming layer that puts Onebrief on classified environments
• Partner with Governance, Risk, and Compliance (GRC) and mission owners on STIGs, CVE remediation, audit prep, and controls work

Success means a platform that:

• Stays up under real operational load
• Ships trusted artifacts to every profile we run
• Passes audits without fire drills

Qualifications

• 5+ years operating production infrastructure in DevOps/DevSecOps, Platform, SRE, Cloud, or Infrastructure roles
• 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
• Ability to obtain a SECRET clearance

Requirements

• Active US SECRET or TOP SECRET security clearance (nice to have)
• Government cloud expertise (AWS GovCloud, Azure Government) (nice to have)
• FedRAMP, IL4/IL5, IL6, or JWICS environment exposure (nice to have)
• Audit experience (FedRAMP, SOC 2, or equivalent) (nice to have)
• Big data and distributed data experience (nice to have)
• Prior experience supporting defense, intelligence, or other regulated industries (nice to have)
