About Gallagher
Gallagher is a global leader in high-tech solutions, renowned for innovation and excellence. With a significant market presence in over 160 countries, we protect some of the world's highest security environments and agricultural businesses. We are now embarking on a company-wide S/4 HANA transformation that will shape how we operate and grow into the future. As we build our transformation team, we're seeking an Organisational Change Manager to lead the change process and drive successful adoption across the business.
The Opportunity
A pivotal role within our global S/4 HANA transformation programme, the Organisational Change Manager will lead the development and execution of our change management strategy. You'll play a key part in guiding individuals and teams through the transition to new systems and processes, embedding change and ensuring long-term adoption across the business.
Working cross-functionally with stakeholders – including ELT, functional leads, change champions, and external partners – you’ll deliver tailored communications, change plans, training initiatives, and readiness assessments, all aligned to the principles of “out of the box” implementation.
The Fit
Success in this role requires more than just change expertise — it’s about being a trusted advisor, an empathetic communicator, and a strategic thinker who can bring people on the journey. You'll be working in a dynamic, fast-paced programme with multiple workstreams and diverse stakeholders, so your ability to navigate complexity and inspire confidence will be key.
We’re looking for someone with a proven track record in managing change across large-scale, enterprise-level ERP transformations. To succeed, you’ll need:
- Demonstrated experience leading change in global programmes (ideally involving SAP S/4 HANA)
- Strong stakeholder management and influencing skills across all levels
- Hands-on experience with change planning, communications, and business readiness
- Familiarity with structured change frameworks (e.g. ADKAR, Prosci, Kotter)
- A confident, adaptable, and collaborative style with strong facilitation and storytelling skills
