💰 £70,000 to £85,000 

A fast-growing, private equity-backed, multi-site business is looking for a Finance Integration Manager to take ownership of onboarding newly acquired businesses into the central group finance function.

This is a highly visible, hands-on role within an ambitious buy-and-build environment, where acquisitions are a key part of the growth strategy.

The position will suit someone who enjoys getting into the detail, understanding how newly acquired businesses currently operate, and leading the full finance integration process from onboarding through to implementation and adoption.

• Finance systems perspective

• Banking and treasury setup

• Process and controls perspective

• Data and reporting perspective

• Operational onboarding perspective

You will work closely with senior leadership, operational teams and newly acquired businesses to ensure integrations are delivered smoothly, efficiently and with minimal disruption.

Key responsibilities:

• Lead end-to-end onboarding of newly acquired businesses into the group finance function

• Manage finance systems implementations, migrations and integrations

• Coordinate setup of banking, payments, reporting and finance workflows

• Review existing finance processes and identify improvements and efficiencies

• Support automation and standardisation across the wider group

• Act as the key finance contact throughout the acquisition integration process

• Work closely with stakeholders across Finance, Operations, IT and senior leadership

Ideal background:

• Qualified accountant (ACA / ACCA / CIMA)

• Experience integrating acquired businesses into a group structure

• Strong finance systems and implementation exposure

• Comfortable working in fast-paced, acquisitive or multi-site environments

• Strong communication skills with a proactive, hands-on approach

• Enjoys problem solving, process improvement and operating autonomously

This is an excellent opportunity to join a high-growth business where you can genuinely shape how the finance function scales over the coming years.
