What will your key responsibilities be?

  • Adapt pack process conditions as required to ensure that all packs run efficiently and meet required semi-finished and finished product specifications, quality standards and efficiency targets.

  • Utilise best practice packaging experience to deploy validated packaging formats across the network with minimal disruption to operations and minimal expense costs to the business.

  • Initiate, coordinate and execute line trials at appropriate supply locations to confirm that quality attributes and performance metrics are achieved.

  • Coordinate the creation of high quality prototypes to gauge consumer desirability, influence teams and support customer collaboration.

What can you expect from Mars?
