Job description

We are partnering with a high-growth, private equity-backed services platform to appoint an Interim Integration Manager as part of an ambitious buy-and-build strategy.

Backed by a leading mid-market investor, the business has experienced rapid expansion through a combination of strong organic performance and an active acquisition programme, having completed several transactions to date. Operating in a large and fragmented European services market, the platform is well positioned to consolidate its space and drive long-term value creation.

This is a hands‑on, in‑house role within a lean team working closely with the C‑suite, focused on leading post‑acquisition integration activity across multiple geographies while supporting value creation initiatives and ensuring acquisitions are successfully embedded into the wider platform.

Responsibilities

• Lead post‑merger integration planning and execution across multiple acquisitions
• Coordinate integration workstreams across functions including finance, operations, HR, IT, commercial, and legal
• Develop and manage detailed integration plans, timelines, and synergy tracking frameworks
• Work closely with senior leadership teams within acquired businesses to support onboarding and change management
• Identify and mitigate integration risks, ensuring minimal disruption to business performance
• Drive operational alignment and best practice implementation across the platform
• Monitor and report on integration progress, KPIs, and value creation initiatives to the C‑suite and investors
• Support transformation, process improvement, and organisational alignment initiatives where required
• Collaborate with the M&A and Corporate Development teams to ensure seamless handover from deal execution into integration
• Manage multiple integration projects simultaneously in a fast‑paced, entrepreneurial environment

Candidate Profile

• Experience within Integration, Transaction Services, Consulting, Corporate Development, PMO, or a similar environment
• Prior post‑merger integration experience within a private equity‑backed or acquisitive business strongly preferred
• Strong project management and stakeholder coordination skills across cross‑functional teams
• Experience integrating acquired businesses and driving operational alignment across organisations
• Commercially minded with strong analytical and problem‑solving capabilities
• Hands‑on, detail‑oriented, and comfortable operating in a fast‑paced, evolving environment
• Strong communication and influencing skills, with exposure to senior leadership teams
• Ability to build relationships quickly and manage change effectively across diverse teams and cultures
• Sector experience not required; candidates from any industry background will be considered
