Integration Manager – Post Merger Integration (United Kingdom)

This is a remote position.

Our new client is a rapidly growing, private equity-backed startup in the travel experiences industry. The company pursues an international buy-and-build strategy, acquiring established, founder-led tour and experience businesses and working with their leadership teams to accelerate growth, professionalise operations and build scalable group capabilities.

As its international portfolio expands, the Integration Management Office ensures that acquisitions deliver sustainable value while preserving the entrepreneurial strengths, local expertise and customer experience that made each business successful.

The Role

We are looking for an experienced Integration Manager to lead post-merger integration programmes across the group’s growing portfolio.

Reporting to the VP, Integration & Operations, you will work across the full M&A lifecycle: partnering with the M&A team before close to validate integration assumptions and develop integration and value-creation plans, then leading execution alongside acquired company management and group functional leaders.

You will combine strong programme management with commercial and operational judgement. This means understanding how an acquired business operates, helping define its future Target Operating Model, translating the investment thesis into a practical Value Creation Plan, and ensuring that synergies and transformation initiatives deliver measurable results.

Target Operating Model & Transformation

• Work with functional leaders and acquired management teams to define appropriate Target Operating Models.
  
• Assess existing processes, organisational structures, systems and capabilities, identifying the changes required to reach the target state.
  
• Help determine what should be standardised or centralised at group level and what should remain local.
  
• Support process standardisation, shared-service implementation, systems migration and organisational redesign.
  
• Ensure transformation initiatives are practical for small and medium-sized founder-led businesses.
  

Value Creation & Synergy Tracking

• Translate the investment case into a measurable Value Creation Plan.

• Work with Finance and functional leaders to validate realised benefits.
  
• Identify delivery gaps early and drive corrective action.
  
• Develop reporting that gives leadership clear visibility of integration progress and value creation.
  

Integration Capability Building

• Help develop and improve the group’s integration methodology, playbooks, templates and governance.
  
• Build a repeatable integration approach that can scale with increasing acquisition activity.
  
• Capture lessons learned from each acquisition and incorporate them into future due diligence and integration planning.
  
• Help establish a strong integration culture across the group and its portfolio businesses.
  

Requirements
