Change Manager (People and Culture Projects)

As a global leader in facilities services, we connect people and places to make the world work better. Whether directly or indirectly, you’ll play a vital role in supporting our placemakers in delivering exceptional workplace experiences for our customers. Together, we make space for people and businesses to thrive.

Location: Warsaw, Poland

Language:  English, fluent spoken and written

Main purpose of the role:

You’ll lead the people side of transformation for our Leading Frontline Employer (LFE) initiatives. Your mission: make sure new ways of working stick by engaging people, building capability, and creating the conditions for adoption across multiple countries.

What you’ll do:

• Facilitate country teams through gaps analysis and readiness conversations, helping them identify what needs to change and co‑create action plans.
• Design and activate a work‑backward roadmap for adoption, including stop‑gaps and hypercare plans.
• Engage and enable local champions, managers, and influencers—coaching them to lead change in their context.
• Create and deliver tailored communications and training plans based on audience segmentation and impact analysis.
• Experiment and adapt: test different levers (comms, learning, nudges), track adoption metrics, and pivot quickly when signals show risk.
• Measure and act: monitor readiness and adoption through dashboards, pulse checks, and feedback loops; adjust interventions to close gaps.
• Package what works into a change toolbox (templates, playbooks, dashboards) for reuse across future projects.
• Partner closely with L&D, Internal Comms, and country “mirror” organizations to ensure alignment and local ownership.

What success looks like:

• Countries feel supported and engaged, not “rolled over.”
• Adoption KPIs (usage, behavior change) hit targets within agreed timelines.
• Champions and managers are activated and confident.
• A reusable change enablement toolkit is in place for future initiatives.

What you bring:

• Proven experience leading adoption and behavior change in multi‑country or enterprise‑scale programs.
• Hands‑on track record with impact assessments, audience analysis, and training plan design.
• Ability to facilitate workshops, coach leaders, and build trust across cultures.
• Comfort working strategically and tactically—from shaping the roadmap to writing comms or running hypercare clinics.
• Agility and creativity to experiment with approaches and learn fast.
• Persistence and drive to remove barriers and keep momentum.
• Strong communication skills in English (written and spoken); additional languages a plus.
