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/m‐services) while also supporting automation and standardization.Job Responsibilities Level 3 Operations & Technical Escalation (Core Responsibility)Act as the L3 escalation point for complex

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/work‐around, risks and next stepsPlatform Lifecycle Management (Upgrades, Patching, Stability)Plan and execute OpenShift lifecycle activities such as version upgrades (cluster upgrades and operator upgrades), patching, security hardening, certificate management, and renewal processesValidate platform readiness before changes: capacity, compatibility, performance, known issuesMaintain high availability and resilience: backup/restore strategy support (including etcd backup practices), disaster recovery readiness, and operational runbooksEnsure operational compliance with defined maintenance windows and change governanceVMware‐to‐OpenShift Virtualization Transformation
