  • Co-ordination and/or production of the calculation of benefits and technical support for the delivery of international benefits.
  • Managing ad-hoc projects as required, driven by the need to respond to administrative, legislative changes and governance requirements.
  • Both maintaining and enhancing the profile of the International Benefits Team as a centre of excellence and expertise.
  • Managing relationships with actuarial, legal, financial and other advisors as well as in-house teams such as other benefit teams, rewards, payroll, global mobility and tax, globally across Mars.

  • An industry competitive salary and benefits package.
  • A flexible schedule that’s designed to give you the work/life balance you need to be at your best.
