Job description

Duration: contract to run until 11/10/2027

Rate: up to £483 p/d Umbrellainside IR35

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.

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.

• 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.

All profiles will be reviewed against the required skills and experience. Due to the high number of applications we will only be able to respond to successful applicants in the first instance. We thank you for your interest and the time taken to apply!
