Change Manager

O’Brien is embarking on a major enterprise transformation — modernising systems, processes, and ways of working across the business.

We’re looking for an experienced Change Manager to play a pivotal role in ensuring this transformation is not just delivered — but adopted, embedded, and sustained.

Reporting to the Head of Talent Acquisition & Program Change, you’ll work at the heart of the program, partnering with senior leaders and delivery teams to turn complex change into practical, people-first outcomes that drive real business impact.

What You’ll Be Doing

Enterprise Change Strategy & Delivery

• Lead and execute end-to-end change strategies aligned to the PhO’enix program roadmap
• Assess impacts across frontline, operational, and corporate teams
• Embed structured frameworks (e.g. Prosci / ADKAR) to drive adoption and sustainability
• Ensure change is fully integrated into program governance and delivery rhythms

Stakeholder Engagement & Influence

• Partner with Executive, Senior and Frontline Leaders to drive ownership of change
• Build strong relationships across Operations, Technology, and People & Culture
• Manage resistance and drive engagement through targeted interventions and coaching
• Influence without authority in a complex, multi-stakeholder environment

Communication & Enablement

• Deliver clear, compelling change and communication plans across the organisation
• Equip leaders with the tools, messaging, and confidence to lead their teams through change
• Partner with training teams to ensure effective learning and readiness delivery

Adoption & Business Readiness

• Track and report on change adoption, readiness, and engagement metrics
• Conduct readiness assessments and implement feedback loops to improve outcomes
• Identify risks early and take proactive action to keep adoption on track

People, Capability & Culture

• Align change initiatives with capability uplift, role design, and workforce planning
• Coach leaders to strengthen change leadership capability
• Contribute to building enterprise-wide change maturity at O’Brien

What You’ll Bring

Essential

• Proven experience as a Change Manager on large-scale transformation programs
• Strong expertise in structured change methodologies (Prosci, ADKAR, APMG, etc.)
• Experience delivering change across technology, systems, and process transformations (ERP/CRM)
• Ability to influence stakeholders at all levels, including executive leadership
• Exceptional communication, facilitation, and stakeholder engagement skills
• Confidence operating in fast-paced, complex, and evolving environments

Desirable

• Experience in field-based, operational, or customer-centric organisations
• Exposure to enterprise system implementations or core platform modernisation
• Background in building change capability or centres of excellence
• Coaching or leadership development accreditation
