Why Join Us?

We care about the world and your future. Mars offers competitive compensation and benefits along with some great perks, like fun freebies and best-in-class development. As a Mars Associate, you have our ongoing commitment to your growth and development as you work across our world-famous brands. The world we want tomorrow starts with how we do business today, and we're here to support you every step of the way.

The Role

Royal Canin is embarking on a major business transformation programme, introducing new technology, standardised processes, enhanced data and analytics, and dedicated change management to support future growth.

As part of the first implementation wave in 2027, the European Key Accounts (EKA) team is seeking a Master Data Controller & ERP Key User to provide critical operational support during the transition.

This role combines responsibility for maintaining accurate end-to-end master data across major European customers with acting as the key user for the Microsoft Dynamics Navision ERP system. Working with pan-European stakeholders in a fast-paced, entrepreneurial environment, you will support daily operations, drive system improvements, lead technical projects, and play a key role in ensuring business continuity throughout the transformation journey.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
