Job Description:

As we work to transform and optimize Mars, a new program has been mobilized by the Mars leadership team.

This transformation requires thought leadership, quality decision making, deep technical know-how, and an ability to navigate complex business challenges while applying a holistic and multi-disciplinary approach to each of these mega processes.
