Senior Engineer (Kubernetes Orchestrator)

Essential Qualifications/Experience:

·       4+ years of dedicated, hands-on experience in DevOps or Platform Engineering roles

·       4+ years of sustained experience designing, deploying and maintaining highly available production Kubernetes clusters, heavily utilizing the SUSE Rancher ecosystem

·       A solid track record of leading complex migrations, moving legacy virtualized applications into containerized, microservice-based architectures

·       Expertly provision, secure, and lifecycle-manage large-scale, multi-cluster Kubernetes environments using SUSE Rancher UI/API and Rancher Manager

·       Write modular, reusable code to automate infrastructure provisioning across hybrid environments using Ansible

·       Architect and maintain sophisticated, zero-downtime deployment pipelines using GitOps principles with Gitlab, ArgoCD or Rancher Fleet

·       Author/manage advanced Helm charts and manage complex stateful and stateless deployments

·       Engineer comprehensive monitoring and logging stacks (Prometheus, Grafana, ELK) to establish SLIs/SLOs and configure automated remediation. Experience with Rancher Observability is a plus

·       Develop robust automation scripts in Python or Bash

·       Rapidly diagnose and resolve high-severity incidents across the entire stack, from kernel-level container issues to complex network routing failures

·       Comprehensive understanding of the underlying architectures of RKE, RKE2, K8S /K3s and knowing exactly when to apply each distribution

·       Knowledge of zero-trust models, Rancher RBAC, Pod Security Admissions, container scanning and enforcing governance

·       CNIs tools (Calico, Cilium, Canal) deep understanding of Software Defined Network and Container Networking, network policies and managing complex Ingress and Service Mesh (Istio) architectures

·       Expert knowledge of Container Storage Interfaces (CSI), disaster recovery planning and managing highly available storage solutions like SUSE Longhorn

·       Extensive practical experience operating distributed Kubernetes environments across a mix of bare-metal, on-premises hypervisors (vSphere, Nutanix), and public clouds (AWS, Azure, GCP)

·       Experience acting as a technical escalation point, guiding junior team members, and establishing DevOps best practices across development teams

DUTIES/ROLE:

·       Design, build, and evolve highly scalable, secure, and resilient Kubernetes platforms utilizing SUSE Rancher as the central management plane

·       Handle the end-to-end lifecycle of RKE/RKE2 clusters (provisioning, scaling, patching and upgrading) across hybrid, multi-cloud or bare-metal environments with minimal to zero downtime

·       Develop and maintain automated CI/CD pipelines and implement GitOps workflows (using tools like Gitlab, ArgoCD or Rancher Fleet) to streamline continuous application delivery

·       Monitor platform health using tools like Prometheus and Grafana, respond to system alerts and troubleshoot complex containerized workload issues

·       Enforce security policy's, including network policies, Rancher RBAC configurations and automated container image scanning

·       Proactively monitor resource utilization (CPU, memory, persistent storage) to right-size clusters, scale nodes dynamically and optimize cloud or on-prem infrastructure

·       Create and maintain technical documentation, including runbooks and architecture diagrams
