Project Manager - Integrations

Lead Critical Delivery Activities on a Major Enterprise Transformation Programme

Hybrid - Remote / Mountsorrel

Are you an experienced Project Manager with a proven track record delivering large-scale integration, cutover and hypercare activities within complex transformation programmes?

We're seeking a delivery-focused Project Manager to play a key role in Project Falcon, ensuring the successful coordination and execution of critical programme phases from integration through to go-live, stabilisation and transition into business-as-usual support.

This is an opportunity to work at the heart of a major enterprise transformation programme, leading cross-functional teams through some of the most business-critical stages of delivery.

The Opportunity

As Project Manager, you will take ownership of integration planning, cutover readiness and hypercare coordination across a complex technology landscape.

You will work closely with business stakeholders, technical teams, testing functions, suppliers and programme leadership to ensure activities are aligned, dependencies are managed, risks are mitigated and the organisation is fully prepared for deployment and post-go-live support.

Success in this role will come from your ability to bring structure, control and pace to high-profile programme delivery, ensuring smooth transitions and operational readiness throughout the programme lifecycle.

What You'll Be Doing

Integration Management

• Lead the planning and coordination of end-to-end integration activities across multiple systems and workstreams.
• Manage dependencies between technical, business and supplier teams.
• Ensure integration deliverables are completed in line with programme milestones.
• Drive issue resolution and support integration testing activities.
• Coordinate readiness activities for SIT and UAT phases.

Cutover Planning & Execution

• Develop and maintain detailed cutover plans and runbooks.
• Coordinate cutover activities across multiple teams and third-party suppliers.
• Identify and mitigate risks that could impact successful deployment.
• Drive business and technical readiness assessments.
• Lead cutover governance, rehearsals and deployment planning activities.
• Manage command-and-control activities during go-live events.

Hypercare & Service Transition

• Coordinate hypercare planning and execution following deployment.
• Manage prioritisation and resolution of post go-live issues.
• Monitor stabilisation activities and service performance.
• Ensure effective handover into operational support teams.
• Capture lessons learned and support continuous improvement activities.

Risk, Dependency & Stakeholder Management

• Maintain ownership of programme risks, issues, assumptions and dependencies.
• Escalate delivery concerns proactively and drive resolution.
• Influence stakeholders across business, technology and supplier organisations.
• Provide clear reporting to programme leadership on readiness, risks and milestone achievement.

About You

You are a delivery-focused project professional who thrives in complex enterprise environments and enjoys managing high-profile deployment activities.

You will be:

• An experienced leader of integration, cutover and hypercare activities
• Comfortable operating in large-scale transformation programmes
• Highly organised with strong planning and coordination skills
• Skilled at managing multiple stakeholders and competing priorities
• Resilient under pressure during critical programme milestones
• An excellent communicator capable of driving accountability across diverse teams
• Focused on achieving successful business outcomes and operational readiness

Essential Experience

• Significant Project Management experience within large-scale technology or business transformation programmes.
• Considerable experience leading Integration, Cutover and Hypercare activities.
• Proven track record coordinating multiple workstreams through testing, deployment and go-live.
• Experience managing complex risks, dependencies and delivery readiness activities.
• Experience working across business, technical and supplier organisations.
• Demonstrable stakeholder management and governance experience.
• Experience supporting service transition and operational handover activities.
• Ability to operate effectively within structured programme delivery frameworks.

Desirable Experience

• Experience delivering programmes involving SAP S/4HANA, SAP ECC or wider SAP landscapes.
• ERP implementation or transformation programme experience.
• Exposure to data migration, testing, infrastructure, service transition or application integration activities.
• Experience within manufacturing, logistics, supply chain, construction materials or other operationally intensive environments.

Qualifications

• Degree qualified in Technology, Engineering, Business or a related discipline, or equivalent practical experience.
• PRINCE2, PMP, APM or equivalent project management certification.
• Additional programme delivery or service management qualifications would be advantageous.

This role offers the opportunity to lead some of the most critical phases of a major enterprise transformation programme. You'll take ownership of integration, cutover and hypercare delivery, helping to ensure a successful transition from programme implementation into operational success.

SAP programme experience is highly desirable, but candidates with strong integration, cutover and hypercare delivery backgrounds gained in other large-scale enterprise environments are strongly encouraged to apply.

If you're passionate about delivering complex transformations and have a track record of leading successful go-lives and stabilisation activities, we'd love to hear from you.

Apply today and help drive one of the most significant transformation programmes in the organisation.
