About Havas Media Group
Havas Media Group is part of the sixth largest advertising network in the world, Havas Group, which is owned by French mass media holding company, Vivendi. We are headquartered out of St Pancras, London, and along with offices in Leeds, Manchester and Edinburgh, we operate globally. Our CEO is Patrick (‘Paddy’) Affleck. Our overarching mission is to make a meaningful difference to the brands, businesses, and lives of the people we work with. Our solution is simple: we identify and create meaningful media experiences to deliver meaningful growth for our clients. In the last two years, we’ve undergone a transformation that’s seen us bind together nine agencies into three core agency brands and propositions:
Havas Media - through which we deliver meaningful outcomes through meaningful media
Havas Market - through which we help clients build meaningful retail experiences
Havas Entertainment - through which we help clients create meaningful moments in culture
In 2026, we’ve strengthened group-wide capabilities and expertise to match clients’ needs to unlock emerging growth opportunities in the ‘new economy’. Our acquisitions of leading agencies Search Laboratory, additive+ and Expert Edge are helping turbocharge our capabilities in search, DCO and ecommerce – with more to come. We also launched a dedicated B2B division, Havas Business, to help clients seize on the huge opportunity of B2B marketing for clients.
We successfully won 16 new clients and retained a further 7, including BBC, Matalan, Homebase, Sega, Bumble, Bethesda and Dr Marten, with our most recent exciting wins of Ocado and Abercrombie and Kent. We have also recently won a number of industry awards, Beer and Pub Association IPA Effectiveness Silver, BBC Outdoor Media awards Brand Building (Gold), Domino’s Outdoor Media awards Cross Format (Gold), Maersk Grand Prix for Effectiveness with WARC and Kia, Best Use of Search in the UK Search awards. Above are some of the reasons why we’re on Campaign’s ‘Best Place to Work’ list each year and our Talent team has been awarded the IPA Gold CPD Accreditation. But we’re more than just great work and awards. Havas Media Group is a place where you can make things happen by pursuing your professional and personal dreams. As such, we’ve also launched the ‘Meaningfully Daring Side Hustle’ programme, while Havas Boost announced its first investment into STEM educational toys business, Ambessa Play.
The Role
This role is across both the Hyundai and Viatris accounts (50/50 split). Two great brands to work on as you progress in your career.
This role will be assisting the Account Director and Client Partner in managing the accounts while also driving innovation and maintaining strong day to day management across various business areas connected to each account. Key will also be managing and ensuring happy and motivated Executives across both accounts to deliver excellence in all aspects of our client partnerships.
Hyundai
Hyundai is one of the top 15 car manufacturers in the UK. We have a long and established relationship with the account (along with Kia/Genesis) for over 14 years and have continued to grow our European relationship with them. With the continued race to electrification and becoming carbon neutral it is interesting times in the automotive industry. Their recent models across IONIQ 6 and IONIQ 5N have put them in an exceptionally strong position and they are firmly in the fight to become the UK EV leader. It’s a challenging but exciting time in the auto industry as brands fight to win out in this space!
Across 2026/24 we have delivered some really exciting work and helped them drive business growth by balancing brand and performance media. We are about to be briefed on 2026 which no doubt will continue to focus on the electrification agenda and how we continue to grow the brand which in turn will hopefully allow us to showcase great work and the power of our planning in delivering meaningful media. We have our eyes on some award winning work!
Our contract is held through Innocean (responsible for delivering creative and digital) and therefore they essentially are our client too. It is therefore key we balance both relationships along with our European colleagues too through the whole process. We have great clients who are engaging and passionate but also good fun socially….we have been receiving excellent service satisfaction scores so we are looking for someone who can continue to help support the team in delivering this. An interest in cars and or the carbon neutral agenda is also a plus but not a deal breaker!
