Operations Manager (OpenShift PaaS) (REF5862A)

Job description

Lead day-to-day operations of our managed OpenShift service, part of a fleet of Openshift clusters for several enterprise customers. Who we are: We are T-Systems’ Managed Container Platforms team. We run Red Hat OpenShift as a managed service across multiple data centres and Open Telekom Cloud, with a SUSE Rancher service alongside. Customers include regulated banks and health insurers, so audits and compliance are part of everyday work. How we work: Our installation team builds new platforms and hands them over to operations, which runs them under ITIL processes in ServiceNow. We are designing Zero-Touch Operations The team is growing, with open roles from junior to expert. As an Operations Manager, you own how the service runs every day: reliability, SLAs, escalations and the operations team that delivers them. You connect engineering, operations, partners and customers, so work and ownership never fall between teams. It is a leadership role with real influence: you set operational priorities with the Global Service Owner and report service performance to senior management every month. In this position, you will: Own SLAs and incident, problem and change management across the fleet, including major incidents and the monthly KPI report. Lead the operations team day to day: priorities, escalation coverage, coaching, performance and hiring. Make ownership explicit with RACIs, OLAs and escalation paths across installation, network, storage and application teams and partners. Run a clean build-to-run handover and turn recurring operational pain into engineering backlog items. Drive our Zero-Touch Operations roadmap: automated upgrades, patching and certificate handling. Keep the fleet audit-ready for regulated customers: CVE and vulnerability management and audit evidence (e.g. ISO 27001, BSI C5, SOC 2). Bring AI into operations where it pays off, such as incident correlation and vulnerability prioritisation. Act as senior escalation point for customers: lead service reviews, onboard new customers, steer transitions and recover at-risk relationships. Requirements: 5+ years leading IT operations or service delivery, including people management of technical teams. Solid working knowledge of Red Hat OpenShift or Kubernetes in a managed-service setting, enough to challenge engineers and vendors. Deep ITSM practice under ITIL 4: incident, problem, change and major-incident management, ideally in ServiceNow. Experience with regulated customers and external audits such as ISO 27001, BSI C5 or SOC 1/2. A track record of stabilising a struggling service, shown in better SLA, MTTR or incident numbers. An automation mindset: you have driven IaC or GitOps adoption with tools such as Terraform, Ansible or Argo CD. Fluent English and confidence presenting to customers and senior management. Advantages: Multi-cloud operations on AWS, Azure, GCP or Open Telekom Cloud. OpenShift Virtualization or Red Hat OpenStack Platform. ITIL 4 Strategic Leader certification.
