Job Description

Stefanini Group is seeking a Senior Compute Engineer specialized in Red Hat OpenShift to strengthen our Compute Operations team and provide Level 3 (L3) expert support for enterprise customers running critical workloads on container and virtualization platforms. 

This role is a key technical position focused on day-to-day operations, stability, and continuous improvement of OpenShift-based platforms. The engineer will act as the highest escalation point for complex incidents and problems, support platform lifecycle activities (upgrades, patching, performance tuning), and contribute to platform modernization initiatives - including VMware-to-OpenShift virtualization transformation programs. 

The ideal candidate combines strong troubleshooting skills, deep infrastructure understanding, and hands-on OpenShift expertise, with the ability to work in a structured operational environment (ITIL/ managed services), while also supporting automation and standardization. 

Job Responsibilities:

Level 3 Operations & Technical Escalation (Core Responsibility):

• Act as the L3 escalation point for complex technical issues related to: 
• Red Hat OpenShift clusters (control plane, worker nodes, networking, storage, authentication) 
• OpenShift Virtualization (KubeVirt) and VM-based workloads hosted on OpenShift 
• Linux OS level issues impacting cluster stability or workloads. 
• Own and drive resolution of: 
  • Major Incidents (P1/P2) with deep technical investigation and rapid recovery focus 
  • Recurring incidents through Problem Management (root cause analysis and permanent fixes). 
• Lead deep troubleshooting activities: 
  • cluster degradation, node failures, API instability, etcd performance issues 
  • networking issues (ingress, routes, DNS, CNI, service connectivity) 
  • storage issues (persistent volumes, performance bottlenecks, CSI failures) 
  • workload failures (pods, operators, deployments, stateful applications). 
• Provide clear technical updates during incidents, including impact assessment, recovery plan/ workaround, risks and next steps.

Platform Lifecycle Management (Upgrades, Patching, Stability):

• Plan and execute OpenShift lifecycle activities such as version upgrades (cluster upgrades and operator upgrades), patching and security hardening and certificate management and renewal processes.
• Validate platform readiness before changes: capacity, compatibility, performance, known issues. 
• Maintain high availability and resilience: backup/restore strategy support (including etcd backup practices), disaster recovery readiness and operational runbooks.
• Ensure operational compliance with defined maintenance windows and change governance. 

VMware-to-OpenShift Virtualization Transformation Support (While the role is operational, this is a strategic area of expertise required in the team):

• Support enterprise modernization initiatives involving migration from traditional virtualization platforms (VMware) to OpenShift Virtualization 
• Contribute to: 
  • migration approach definition and technical design support 
  • workload onboarding, validation, and stabilization on OpenShift 
  • performance tuning and operational model definition for VM-based workloads on OpenShift.
• Ensure production-grade operational readiness: monitoring, alerting, backup, patching and support model aligned with managed services standards.

Standardization, Automation & Operational Improvement:

• Develop and maintain operational documentation, including troubleshooting guides, standard operating procedures (SOPs), build standards and reference architectures, operational runbooks for recurring tasks.
• Support automation initiatives using tools such as: Ansible / Automation Platform (preferred), GitOps practices (ArgoCD) where applicable and scripting (Bash / Python) to reduce manual operations.
• Proactively identify improvements to increase platform stability, recovery speed (MTT), repeatability and reduction of human error.

Monitoring, Observability & Performance Management:

• Support and improve observability across the platform, including: 
  • OpenShift monitoring stack (Prometheus / Alertmanager / Grafana) 
  • log management (e.g., EFK / Loki or enterprise logging platforms).
• Troubleshoot performance issues related to compute resource constraints, scheduling and resource requests/limits and cluster scaling and capacity planning.
• Work with customer stakeholders and internal teams to define alert thresholds, reduce noise and false positives and improve operational dashboards and health reporting.

Security & Compliance Support:

• Ensure the platform is operated in a secure manner aligned with enterprise expectations: 
  • RBAC best practices 
  • integration with enterprise identity providers (LDAP / AD / SSO) 
  • secure cluster configuration and segregation 
  • Support vulnerability remediation and platform hardening initiatives 
  • Collaborate with Security teams for audits, compliance requests, and evidence collection. 

Job Requirements

 Mandatory Technical Skills:

• Strong hands-on experience with Red Hat OpenShift administration and operations.
• Strong Linux background (RHEL preferred), including troubleshooting OS performance, services, networking, and storage.
• Solid understanding of Kubernetes fundamentals: pods, deployments, services, ingress, namespaces, RBAC, operators.
• Experience troubleshooting infrastructure-related issues across compute, network, storage, and platform services.
• Experience working in production environments with uptime and SLA commitments.

Mandatory Professional Skills:

• Proven ability to operate as Level 3 support, including deep troubleshooting, structured root cause analysis and ownership until resolution. 
• Ability to communicate clearly with customers (technical and non-technical stakeholders) and internal teams (L1/L2/architects/project teams).
• Strong documentation discipline and operational mindset.

Preferred/ Nice-to-Have Skills:

• Experience with OpenShift Virtualization (KubeVirt) and VM-based workloads. 
• Experience supporting VMware environments and understanding virtualization concepts: vSphere architecture, clusters, HA/DRS, storage/datastores, VM lifecycle.
• Experience with automation tools: 
  • Ansible / Red Hat Ansible Automation Platform 
  • GitOps tools (ArgoCD) 
  • Infrastructure as Code practices.
• Experience with enterprise storage and CSI integrations.
