Integration Project Manager job at London Full Time

London (Hybrid) | Up to £80,000 | Permanent or 18-24 Month FTC

A high-growth, private equity-backed professional services platform is looking for an experienced PMI Delivery Manager to lead post-merger integration across a fast-scaling portfolio.

This is a high-impact leadership role at the centre of an ambitious buy-and-build strategy, offering exposure to multiple acquisitions, senior stakeholders, and end-to-end value creation in a PE environment.

Ideal for candidates from management consulting (M&A / transformation) or in-house integration / programme delivery roles, looking to step into a role with real ownership and pace.

You will take full ownership of post-merger integration delivery, managing multiple deals concurrently from Day 1 through to stabilisation and optimisation.

Working directly with senior leadership, you’ll ensure integrations are:

• Delivered at pace and with discipline
• Aligned to the target operating model
• Driving measurable synergies and performance improvement

This role combines programme leadership, stakeholder management, and hands-on delivery in a fast-moving PE-backed environment.

• End-to-end PMI delivery: Own integration programmes from deal close through to full operational alignment
• Programme leadership: Manage multiple concurrent integrations across functions (Ops, Finance, HR, IT)
• PMO & governance: Establish best-in-class integration structure (plans, RAID, reporting, critical path)
• Stakeholder management: Work closely with exec leadership, functional teams, and acquired businesses
• Value delivery: Track synergy realisation and ensure delivery of value creation targets
• Operating model integration: Align processes, systems, and ways of working across acquired entities
• Playbook development: Continuously refine integration frameworks to improve speed and quality

We’re particularly targeting candidates with:

• 5-8+ years’ experience in management consulting (M&A / transformation) or PMI delivery
• Strong track record leading complex programmes or integrations end-to-end
• Experience in PE-backed, high-growth, or multi-entity environments (highly desirable)
• Ability to operate across both strategic planning and hands-on execution
• Excellent stakeholder management, including Exec / Board-level exposure
• Strong commercial mindset with a focus on value creation and outcomes

Exposure to operating model design, process integration, and systems transformation is important.
