JOB SUMMARY -- ESSENTIAL FUNCTIONS/DUTIES

The Platform and Kubernetes Engineer will manage, architect, and modernize our container orchestration platforms across on-premises, air-gapped, and secure cloud environments. In this role, you will serve as the primary subject matter expert for our container platforms - supporting bare-metal and lightweight edge/dev clusters (Talos, Linux, MicroK8s) as well as enterprise orchestrators (Red Had OpenShift) while potentially supporting integration into secure hybrid cloud boundaries (AWS FENCES). The Platform and Kubernetes Engineer will work closely with a collaborative team of System Administrators, DevSecOps Engineers, Cybersecurity Analysts, and Software Developers to provide resilient container infrastructure, automated runner environments, and secure packaging pipelines for our software development community.

Employee will be responsible for the following functions/duties:

• Kubernetes and Platform Operations
• Architect, deploy, patch, and maintain multi-distribution Kubernetes environments across bare-metal, virtualized, and cloud infrastructure, including Talos Linux and MicroK8s.
• Ensure high availability, performance, and resource optimization across development and production clusters.
• Manage container persistent volumes, stateful workloads, and distributed storage clusters (Rook-Ceph and Longhorn).
• Support physical server maintenance, rack deployments, and bare-metal OS provisioning for underlying cluster nodes.

• Cloud Integration & Hybrid Architecture (AWS FENCES)
• Interface on-premises Kubernetes platforms with cloud services, including hands-on administration or integration with AWS Elastic Kubernetes Service (EKS).
• Provision and troubleshoot supporting cloud infrastructure utilizing core AWS services: EC2, S3, VPC, IAM, Lambda, and Network & Application Load Balancers (NLB/ALB).
• Supports the secure network boundary and data synchronization between on-premises developer networks and AWS FENCES

• CI/CD, Runners, and Artifact Management 
• Stand up, configure, and maintain self-hosted pipeline runners, with an emphasis on Actions Runner Controller (ARC) on Kubernetes for GitHub Actions.
• Maintain and secure container registries and artifact repositories (AWS Elastic Container Registry (ECR), Harbor, Nexus, Artifactory).
• Partner with DevSecOps engineers to support code deployment pipelines, version control integrations (Git, GitHub, AWS CodeCommit), and release packaging.

• Network, Security, and PKI Administration 
• Manage the end-to-end lifecycle of SSL/TLS certificates across both Linux operating systems and Kubernetes ingress controllers, ensuring continuous encryption in transit.
• Configure and troubleshoot cluster networking, software-defined networking (SDN), ingress controllers, reverse proxies, and virtual/physical load balancers.
• Enforce security baselines, and access policies in compliance with DoD/DoW cybersecurity standards across air-gapped and connected environments.
• Documentation & Team Collaboration 
• Produce and maintain detailed operational runbooks, disaster recovery procedures, and cluster architecture diagrams.
• Provide escalation support to systems administrators and software development teams encountering infrastructure-level blockers.
