Job Summary

We are seeking an influential and experienced senior director to oversee, deliver and evolve the Mars enterprise curriculum for leaders and senior leaders and our new global Leader Expectations for leaders and managers at all levels.

This pivotal position is central to Mars' strategic ambition to Accelerate our Leadership and Culture Advantage by cultivating a world-class leadership population and pipeline that will contribute to our future business ambitions.

This is supported by an overarching agenda on development excellence, building capabilities that amplify great leadership at Mars through an end-to-end portfolio of global programs which are rooted in Mars' Purpose, Five Principles and Associate Concept. (Learn more about Mars' culture here.)

This role will be responsible for the global development of leaders across the enterprise, working in partnership with Segment talent leads, functional learning teams and other CoEs to deliver a cohesive, integrated curriculum that accelerates world class leadership at Mars.

This role will work in close partnership with peers in the Leader Development CoE to ensure coherence and quality across our shared portfolio and its renewed focus on developing Associates with purpose-driven, people-focused, principles-based leadership practices that have endured in Mars for decades.

In addition to programmatic solutions, this role will be responsible for activating new Leader Expectations and defining the supporting behaviours and competencies for all managers and leaders across Mars. Collaborative partnership with the People & Organization (P&O) function and business leaders will be essential as this work will require activation and alignment across the P&O operating model including multiple Centers of Excellence (from Talent Acquisition to Talent Management and Reward as well as Leader Development).

This work requires complex stakeholder engagement over multiple years including up to the global Mars Leadership Team.

This role requires someone with a proven track record of setting a compelling multi-year vision for leadership capability across a large-scale corporate organization and who can translate this vision into a rigorous, well-sequenced portfolio of solutions.

This role will be critical to further integrating Mars' culture agenda and global Talent Management priorities with Leader Development initiatives.

  • Facilitate work with other CoEs whose development offerings support the Accelerate Leadership and Culture Advantage priority from the Mars Enterprise Strategy. This includes close work with Global Inclusion and Diversity and Health and Wellbeing teams to construct more coherent, cohesive development pathways for leaders, aligned to our leader development architecture and new Leader Expectations.
  • Bring together shared standards and design principles across all programs (whether owned by the Leader Development CoE or other teams) so they feel like one coherent development journey for leaders at different levels of their career to simplify learning journeys.
  • Partner with Segment talent leads, functional learning teams and Mars University learning partners to link leader development requirements that are requested by business areas (Segments, regions, markets and functions) so that there is a more modular approach to all leader development, reducing cost, time and duplication of effort.
  • Leader Expectations: Mars is taking a strategic approach to the next chapter of…
