About this role

Onebrief seeks an Infrastructure Engineer to design and operate secure, production-grade platforms serving military planning software across commercial clouds, government environments, and air-gapped deployments. You'll own end-to-end infrastructure spanning Kubernetes clusters, artifact pipelines, application streaming, and edge appliances while embedding security into every system.

What you'll do

  • Design, develop, and deploy secure production systems across cloud-native and edge appliance environments
  • Build and harden the unified artifact pipeline to ship signed builds across commercial, government, and classified deployments
  • Own end-to-end infrastructure outcomes for critical programs and priority initiatives
  • Embed with cross-functional teams to advise on infrastructure, security, and deployment best practices
  • Partner with GRC and mission owners on compliance controls, STIG hardening, and CVE remediation for IL5/IL6/JWICS environments
  • Operate Kubernetes clusters across multiple profiles and ensure systems remain stable under operational load

What they're looking for

  • Production Kubernetes administration (operators, networking, storage, multi-cluster operations)
  • Cloud infrastructure (AWS, Azure) with ability to design across providers and profiles
  • DevOps/DevSecOps and infrastructure-as-code practices
  • Backend engineering in modern languages (Go, Python, Rust, TypeScript)
  • Application and infrastructure security (identity, network segmentation, secrets management, vulnerability assessment)
  • Air-gapped and disconnected environment deployments
  • FedRAMP/government cloud compliance and audit preparation
  • Full-stack problem-solving and rapid prototyping
