To support this, we’re looking for a detail-oriented and collaborative SAP Release Manager to oversee release planning, coordination, and governance across multiple S/4HANA landscapes. This role will play a key part in ensuring smooth, synchronized delivery of changes from development through to production.

• Own and maintain the SAP release calendar, aligned with program milestones.
• Develop and implement inclusive, effective release governance processes.
• Coordinate transport activity across multiple teams, environments, and S/4HANA instances.
• Collaborate with Mars teams, system integrators, and technical leads to ensure proper sequencing, quality, and compliance.
• Lead release readiness and cutover planning.
• Proactively identify and manage risks, providing updates to senior stakeholders.
• Ensure all release activities follow change management and audit protocols.
• Continuously improve release processes and tools for better efficiency and visibility.
• Foster strong cross-functional collaboration and stakeholder engagement.

What are we looking for?

• 5+ years of SAP release or deployment management experience in large-scale programs.
• Deep understanding of SAP transport and change control in complex, multi-system environments.
• Familiarity with tools like SAP CALM, ActiveControl, and other release automation solutions.
• Strong communication, coordination, and risk management skills.
• Inclusive leadership mindset and a passion for working across diverse teams.
• Experience working with system integrators, business teams, and external partners.
• Ability to thrive under pressure, with a proactive and structured approach.

What can you expect from Mars?

• Work with over 140,000 diverse and talented Associates, all guided by the Five Principles.
• Join a purpose driven company, where we’re striving to build the world we want tomorrow, today.
• Best-in-class learning and development support from day one, including access to our in-house Mars University.
• An industry competitive salary and benefits package, including company bonus.
