JD: Linux Project Manager

Sheffield/Birmingham- 2 Days a week

Immediate to 1 Week NP only.

The Programme/ Project Manager will be working on a setup

for Linux on Mainframe - so someone who has experience of this should be

highlighted please.

The key is someone who can lead the delivery of a supported

Linux hosting service, not simply coordinate server provisioning.

Role purpose

Lead the design, build and operational launch of a RHEL

server offering on IBM Linux ONE. 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 Linux

    ONE / 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.

They do not need to be the deepest engineer in both technologies

but must be technically credible enough to challenge assumptions and resolve

ownership 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, 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.

Best-fit profile: A senior infrastructure PM who has

delivered Linux on IBM Z/LinuxONE services-not a generic PM with only

traditional mainframe application experience or only x86 Linux experience.
