Junior Team Executive Assistant

Vector Media is an independent London media agency, founded in 2025 and based in the heart of Soho. We were built deliberately differently, free from legacy infrastructure and process, to pioneer a service-based partnership model that guarantees delivery for our clients. Our founding directors bring more than 50 years of combined media experience and have worked together as a team for over a decade. That practitioner-first foundation means clients deal with senior media specialists on every brief, and our team gets to learn directly from people who have built and led media functions at some of the UK's most respected agencies. We work with ambitious brands across competitive sectors, on campaigns that span TV, video, OOH, audio, print and digital. We're small, senior, and rapidly growing, and we're hiring people who want to do their best work in an environment built to support it. The Role We're looking for a highly organised, proactive and reliable Junior Team PA to support our senior team and help keep the day-to-day running of the agency moving. This is a hands-on role in a small, fast-growing business, giving you exposure across the leadership team, clients, suppliers and wider agency operations. You'll be responsible for keeping diaries and meetings organised, making sure people have what they need, and picking up the detail that allows the wider team to focus on their work. You'll work closely with senior members of the team and will quickly become someone people rely on. It's a role for someone early in their career who is naturally organised, commercially aware, confident dealing with people and enjoys making things happen.
