• Infrastructure as Code (IaC) & Automation: Drive infrastructure automation by writing and maintaining modular Ansible playbooks. Manage centralized automation execution, RBAC, and workflows using AWX.  

• Engineering Rigor: Maintain a high standard of quality by producing rigorous technical documentation and thoroughly testing all code and infrastructure changes prior to deployment.  

• Operational Excellence: Partner with cross-functional network, storage, and compute teams to ensure services are secure, observable, compliant, and highly resilient.

• Architecture: Understanding of 12-factor application methodologies and modern microservices architecture and how to implement.  

• Containerization: Hands-on experience managing application-level Kubernetes workloads, including Deployments, Services, ConfigMaps, Ingresses, and HPA (experience with Rancher is highly preferred).  

• Pipelines & Tooling: Deep understanding of complex CI/CD pipelines. Proven experience managing and integrating tools like GitLab, ArgoCD, and Harbor.  

• Automation Configuration: Solid hands-on experience with Ansible and AWX to manage and execute complex automation workflows.  

• Systems Thinking: Linux/Unix foundation with a basic understanding of networking, storage, and security in an enterprise environment.
