Role purpose / summary
Lead the design, build and operational launch of a RHEL server offering on IBM LinuxONE. Work with the mainframe, Linux, network, storage, security and service-management teams to define responsibilities and deliver a service application teams can consume.
Essential experience
IBM LinuxONE / IBM Z: Understanding of LPARs, IFL capacity, platform resilience and the chosen virtualisation approach-such as z/VM or KVM.
Enterprise RHEL: Familiarity with provisioning, patching, hardening, monitoring, backup, automation and production support.
Cross-platform delivery: Experience aligning mainframe platform practices with Linux engineering and application requirements.
Infrastructure service launches: Delivery of service catalogues, support models, SLAs, disaster recovery, operational acceptance and onboarding.
Technical project management: Ownership of plans, dependencies, risks, suppliers, budgets and decisions across infrastructure teams.
Key responsibilities
Define the offering: Supported RHEL versions, server sizes, environments, availability tiers and target workloads.
Coordinate the architecture: Platform capacity, virtualisation, networking, storage, security and management tooling.
Confirm workload readiness: Validate application, middleware and vendor support for Linux on IBM Z (s390x)-do not assume x86 workloads can move unchanged.
Establish the operating model: Agree who provisions, patches, monitors, backs up and supports each layer.
Lead a pilot: Prove provisioning, application compatibility, performance, recovery and support processes.
Deliver production readiness: Secure operational sign-off, publish the service catalogue and manage initial onboarding.
Expected deliverables
- Integrated delivery plan and RAID log.
- Agreed architecture and responsibility matrix.
- Capacity, licensing and cost model.
- Provisioning and lifecycle-management processes.
- Security, backup and disaster-recovery acceptance evidence.
- Operational runbooks, support model and service catalogue.
- Pilot results and production go-live approval.
