Linux Project Manager

Sheffield, United Kingdom | Posted on 09/30/2026

The Programme/ Project Manager will be working on a setupfor Linux on Mainframe – so someone who has experience of this should behighlighted please.

The key is someone who can lead the delivery of a supportedLinux hosting service , not simply coordinate server provisioning.

Lead the design, build and operational launch of a RHELserver offering on IBM Linux ONE. Work with the mainframe, Linux, network,storage, security and service-management teams to define responsibilities anddeliver a service application teams can consume.

• IBM LinuxONE / IBM Z: Understanding of LPARs, IFL capacity, platform resilience andthe chosen virtualisation approach—such as z/VM or KVM.
• EnterpriseRHEL: Familiarity with provisioning, patching, hardening, monitoring,backup, automation and production support.
• Cross-platformdelivery: Experience aligning mainframe platform practices with Linuxengineering and application requirements.
• Infrastructureservice launches: Delivery of service catalogues, support models, SLAs,disaster recovery, operational acceptance and onboarding.
• Technicalproject management: Ownership of plans, dependencies, risks, suppliers,budgets and decisions across infrastructure teams.

They do not need to be the deepest engineer in both technologiesbut must be technically credible enough to challenge assumptions and resolveownership gaps.

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, middlewareand vendor support for Linux on IBM Z (s390x)—do not assume x86 workloads canmove 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.

• Integrateddelivery plan and RAID log.
• Agreedarchitecture and responsibility matrix.
• Capacity,licensing and cost model.
• Provisioningand lifecycle-management processes.
• Security,backup and disaster-recovery acceptance evidence.
• Operationalrunbooks, support model and service catalogue.
• Pilotresults and production go-live approval.

Best-fit profile:

A senior infrastructure PM who hasdelivered Linux on IBM Z/LinuxONE services—not a generic PM with onlytraditional mainframe application experience or only x86 Linux experience.
