You will operate in a complex and evolving environment, ensuring delivery is structured, governed and aligned across engineering, IT and business stakeholders.

• Manage end-to-end delivery of PLM projects within agreed time, cost and quality constraints.

• Oversee system implementation delivered by vendors, integrators and internal technical teams.

• Develop and maintain project delivery plans with clear milestones and progress tracking.

• Coordinate across engineering, IT and business teams to ensure alignment of delivery activities.

• Manage interdependencies between PLM systems, engineering data and wider digital workstreams.

• Lead business change activities including stakeholder engagement, readiness and adoption support.

• Manage risks, issues and dependencies, ensuring effective governance and escalation processes.

• Produce clear reporting on delivery status, risks, milestones and overall programme performance.

• Support financial tracking and alignment of delivery activities with budget expectations.

• Act as central coordination point between technical teams and business stakeholders.
