What do you do at Mars and what were you doing before?​

Before Mars, I studied a Masters in Chemical Engineering at the University of Bath. Throughout University I had experience working in R&D for FMCG companies dealing with household cleaning products and dental care, as well as designing an Ice Cream plant in my Design Project. From this I knew I wanted a career creating something I use regularly and where I could physically see the impact of my work in a finished product.

​​​​​​​Therefore, the Engineering scheme at Mars was a great opportunity to develop my career.​ In my first year I was a Project Engineer at the Slough site. I had the opportunity to lead multiple impactful projects through scoping, installation and commissioning ensuring the continuity of the Minstrels and Maltesers production lines.​ I am now moving to the Veghel site in the Netherlands as a Project Engineer to continue working on impactful projects and further my development

What's the best part of the programme?
 I started at Mars as a Site Project Engineer in King’s Lynn as part of the Food segment. I led several projects inside and outside the factory using several different engineering disciplines, from civil and electrical through to process and control. I am now relocating to the London to work on the Global Digital Transformation within the Food segment helping move our sites forward in automation, AI, and data visibility.​

The Engineering Programme truly stretches you and helps you to build on your strengths and develop your weaknesses, by giving you the best support network and flexibility across the business. There is no set standard programme, everyone’s experiences and needs are different, and the flexibility of this scheme represents that.

What makes Mars so special?

I started my career with Mars as a project engineer in King’s Lynn, UK, where I led a number of projects both in and out of the factory. After a year in the UK, I relocated as a project engineer to Toronto, Canada, to continue stretching my engineering and leadership capabilities. ​

Currently, I am a production shift leader in Mississippi, USA – leading factory associates in day-to-day operations & putting my leadership skills to the test with 18 direct reportees

Two things – first is the people at Mars! There’s such a huge depth and breadth of experience, personalities and cultures – it is a very open workplace, everyone looks out for each other, and you will always find the support you need.​

Second would be The Five Principles – it’s refreshing to see a business and its associates truly have common principles at its core, which act as the driving force for all the decisions made, no matter how big or small.
