About the Role: Oliver Wyman is undertaking a firmwide transformation to embed advanced digital and technology-enabled capabilities into the day-to-day work of our consultants and support professionals. We are seeking an Activation & Change Manager to lead global change and adoption efforts for this transformation. This role is critical to ensuring that new tools, workflows, and capabilities translate into real, sustained changes in how colleagues work across consulting and support populations. You will design and orchestrate activation strategies that span central initiatives and localized regional efforts, working closely with product teams, program leadership, communications, and regional stakeholders. The role requires strong change management expertise, senior stakeholder engagement, and the ability to operate effectively across cultures, regions, and levels of seniority. In a typical week, you might translate a product roadmap into a clear, practical activation plan that resonates with consultants on the ground, or work with regional leaders to adapt global initiatives to local realities. Success in this role means seeing new capabilities become everyday ways of working. This position offers the opportunity to lead change at global scale, with direct exposure to senior leadership and meaningful influence on how a top-tier consulting firm evolves its ways of working. Unlike traditional change roles, you will be embedded in a fast-moving, product-driven environment, working on tangible capabilities that are already live and continuously evolving.

Requirements

• 5+ years of experience in change management, transformation, or large-scale enablement roles
• Proven track record of driving behavior change and adoption in complex organizations, such as leading the rollout of new tools, processes, or ways of working across multiple teams or regions
• Strong stakeholder management skills, including experience working with senior leaders
• Experience operating across regions and cultures in a global organization, tailoring initiatives to local contexts while maintaining global alignment
• Excellent communication, facilitation, and problem-solving skills, including the ability to engage both senior leaders and end users
• Comfort operating in ambiguous, fast-evolving environments (e.g., digital, technology, or innovation-driven change)
• Foundational skills at Oliver Wyman — including analytical problem-solving, facilitation, digital fluency, attention to detail, adaptability, and collaboration — will be assessed through interviews and practical discussions.

Responsibilities

• Own the global activation and change strategy, aligned with product releases and major transformation milestones
• Design and coordinate activation waves, including timing, sequencing, and rollout phasing, balancing global consistency with regional flexibility and ownership
• Partner closely with regional leaders and business teams to embed new tools and ways of working into local operating rhythms
• Anticipate and manage change impacts, risks, and resistance, exercising sound judgment on when to intervene directly and when to escalate or involve leadership
• Work closely with product and program management teams to ensure activation timing, messaging, and readiness are aligned
• Act as a senior integrator across activation, communications, and delivery efforts, ensuring alignment on priorities, timing, and messaging from launch through sustained adoption
