Our Programme

Our graduate programmes put you at the heart of a global business, with hands-on experience and tailored learning for curious, driven minds. Start your journey to a career you’ll be proud of today.

From Guinness, Smirnoff and Johnnie Walker to Baileys, Captain Morgan and Gordon’s, Diageo has a stable of premium drinks brands enjoyed the world over. Our Marketing teams play a big role in ensuring our brands live and breathe their purpose and we remain at the heart of celebrations everywhere. 

We want to create future “General Managers” for our brands: balancing critical thinking for the future with real time business performance and understanding. Creating compelling and powerful stories to make our existing brands even stronger will be critical to the ongoing success of our brands – some of which are over 250 years old. But isn’t just about our legacy products, you may also be part of the launch of a new one too. Working as part of a team, you’ll use your creativity, vision and pioneering spirit to bring our brands to life. 

On this three-year rotation programme, you’ll gain experience across both Marketing and Commercial Sales, building a strong foundation for your future career at Diageo.

You’ll rotate through three roles across your time on the programme, giving you exposure to multiple fields which could cover the following areas:

Marketing: you’ll work closely with the Senior Brand Manager, Brand Manager, Marketing Manager, and Commercial teams across the business to support the development and execution of 360° brand plans. You'll drive campaign delivery, performance analysis, budget management, and cross-functional alignment across multiple channels. This is a high-growth role built for a focussed marketer who thrives in fast-paced, consumer-obsessed environments and who is ready to blend creative thinking with sharp business insight.

Commercial: sales & account management, customer marketing, and customer activation. You’ll learn how to take brands like Baileys, Guinness, and Smirnoff to new generations of shoppers, untapped markets, and new occasions, while strengthening customer relationships and ensuring our brands are successfully promoted, available, and well-presented.

Who are we looking for? 

On the qualification side, you’ll need to have acquired or be expecting to obtain an academic degree and be graduating in 2026 or within the last 2 years. You must be proficient in English, and with opportunities across Europe you must be mobile and prepared to relocate geographically during the programme. 

We’re looking for curious, flexible, self-motivated great teammates who turn ideas into action—and who bring integrity, respect, and a passion for learning every day. As we shape the future of our Commercial and Marketing function, we especially welcome applicants with a passion for data and analytics.

Most importantly be you. Bring your ideas, your ambition, and your unique talent. We’ll celebrate it and empower you to reach your full potential.

To be eligible for our graduate programmes, all candidates must have the continuous right to work in UK and IOI and any offer of employment is conditional upon this requirement being satisfied. Diageo does not provide sponsorship to undergraduates and graduates trying to obtain the right to work in the UK.
