Rackner is hiring Kubernetes Engineers across Mid and Senior levels to help design, automate, secure, and operate cloud-native platforms supporting a mission-focused DoD environment. You’ll work hands-on across Kubernetes, cloud infrastructure, GitOps, service mesh, networking, security, and Infrastructure as Code—building reliable platform capabilities that development teams can use at scale.

What You’ll Lead and Build:

• Design, build, and operate secure, resilient Kubernetes platforms
• Automate infrastructure and platform configuration using Terraform, Ansible, Helm, and Infrastructure as Code
• Build and improve GitOps and CI/CD workflows

• Engineer and support Istio/service-mesh capabilities
• Build reusable platform components, including Helm charts, Operators, Controllers, CRDs, and Admission Controllers
• Integrate Kubernetes with cloud services, container registries, and delivery pipelines
• Troubleshoot complex issues across Kubernetes, Linux, networking, containers, and cloud infrastructure
• Strengthen platform reliability, security, performance, and recovery
• Partner with application, cloud, security, and architecture teams to turn requirements into working platform capabilities

Senior engineers may also guide larger technical decisions, lead implementation efforts, and help other engineers grow while remaining hands-on.

• Senior engineers will typically bring 5–7+ years with broader platform ownership, architecture, or technical leadership

Standout Background

• Certified Kubernetes Administrator (CKA)
• Deep experience with Istio or service mesh
• Custom Kubernetes Operators, Controllers, CRDs, or Admission Controllers
• DoD Enterprise DevSecOps Reference Design experience
• Software development, scripting, or platform automation background
• Experience supporting production platforms with active end users
• DoD, federal, regulated, or security-focused engineering environments

Benefits
