Job Description

Location: Poland St, London

We are the long-standing, production partner of choice that has helped brands across borders and cultures for over half a century achieve their business goals. With 2,700 experts in 29 countries across the world, we are a global team of collaborators, innovators, and motivators.

We pride ourselves on creating empowering, safe, and supportive environments for all our employees, regardless of ability, or any other defining factor. We embrace difference through thought, experience, and expertise to maximise potential and bring the greatest benefits for our people and our clients.

We can’t bring big ideas to life without exceptional people. At Tag, we respect individuality and the power of the collective. We want people to be themselves, unafraid to voice ideas, no matter how big they are or who they come from.

In June 2023, Tag was acquired by dentsu Group, Inc, though we remain a distinct brand that is led by Tag Global CEO, headquartered in London. As dentsu’s acquisition of Tag significantly expands content delivery capabilities, Tag’s expertise to deliver personalized, omnichannel content in real-time and at-scale for clients remains unparalleled across the entire customer journey, unlocking marketing effectiveness and efficiency.

Tag and dentsu bring together our innovation and technology infrastructure to help solve clients’ toughest challenges. United in business acumen, we share similar core values, company culture, and embrace a vision “to be at the forefront of people-centric transformations that shape society.”
