Job Description
Job Description Senior Platform Engineer, OpenShift and Kubernetes
The Role
Our client is looking for a senior engineer to own a containerized platform from top to bottom. That covers cluster and storage administration, deployment pipelines, GitOps, and the AWS infrastructure underneath it all.
When something fails, you'll be the one people call. A crashing pod, a stalled pipeline, a persistent volume claim that won't bind, or a service that can't reach its neighbor all land on your desk. You'll track down the cause, write it up, and make sure the problem doesn't come back.
What You'll Work On
- Administer and troubleshoot OpenShift and RKE2 clusters day to day
- Keep deployments flowing through Argo CD and pipelines in GitLab CI/CD
- Build and maintain Ansible automation and Terraform-managed infrastructure
- Support the AWS footprint, including compute, storage, networking, and access
- Lead root cause analysis on incidents anywhere in the stack and document findings and fixes
Technical Background
Kubernetes and OpenShift
- Hands-on administration of OpenShift and/or RKE2 environments
- Solid command of core objects: Namespaces, Deployments, Pods, StatefulSets, Jobs, Services, Secrets, and ConfigMaps
- Persistent storage troubleshooting covering PVCs, PVs, StorageClasses, and volume mounts
- RBAC, ServiceAccounts, secrets management, and sound cluster security practices
Automation and Delivery
- Ansible development, including roles, playbooks, inventories, and broader automation workflows
- Terraform and other Infrastructure as Code (IaC) tooling
- Git, GitLab CI/CD, and GitOps deployment patterns with Argo CD
- Container technologies and registries such as Artifactory, Harbor, or Nexus
Cloud, Linux, and Networking
- AWS services including IAM, EC2, EBS, S3, CloudWatch, and VPC networking
- Troubleshooting cloud instances, access controls, storage, and network configuration
- Deep Linux administration and troubleshooting skills
- Networking fundamentals: TCP/IP, DNS, load balancing, ingress and egress, and service-to-service connectivity
Messaging and Observability
- Apache Pulsar, including managing or troubleshooting topics and other messaging resources
- Grafana, Prometheus, Elasticsearch/OpenSearch, or comparable monitoring and logging platforms
How You Work
- Comfortable isolating problems that cross application code, containers, the cluster, cloud resources, storage, and the network
- Methodical about root cause analysis and clear in writing up what broke and how it was resolved
Clearance and Requirements
- U.S. citizenship required
- Active TS/SCI with CI Poly
- Full-time onsite presence in Richardson, TX
- Drug and alcohol screening applies before hire and may continue on a scheduled or random basis. The employer pays for all testing and follows applicable federal, state, and local law.
