Marketing Executive in London

Overview

Please note: This role is scheduled to start in June 2026.

READY TO DO WORK YOU'RE PROUD OF? At Charlie Oscar, we're not your typical digital marketing agency - we're a team of big thinkers, bold doers, and collaborative problem-solvers. We partner with some of the world's most ambitious brands to help them outsmart, outpace, and outgrow the competition.

How do we do it? By blending data science and creativity to make smarter decisions and create work that actually makes an impact. The numbers give us clarity, but it's our creativity that wins hearts, builds brands, and drives real growth.

Life at Charlie Oscar is fast-paced, exciting, and full of opportunities to learn, grow, and push boundaries. You'll be working alongside some of the sharpest minds in the industry, solving big challenges, delivering work you're proud of, and seeing the difference you make for global brands.

And we know it's not all about work. We make time for fun too - whether it's weekly run club, book and chess clubs, charity fundraisers, Thursday drinks, or epic team socials, there's always something to get involved in and people to connect with.

Most importantly, we hire for attitude and culture add, not just experience. We want curious, ambitious people who aren't afraid to challenge the status quo, bring fresh ideas to the table, and help us shape the future of marketing.

Who We Hire

We look for attitude first. If you're smart, humble, proactive, and genuinely curious – you'll fit right in. We want people who care deeply about their craft, but don't take themselves too seriously. We're building a culture where brave ideas are encouraged, learning is constant, and everyone's voice matters.

If you're already playing with AI to do smarter work, even better. We don't expect you to be a specialist – just inquisitive and excited to find tools to elevate what we do.

AI

At Charlie Oscar, we're looking for people who can show how they use AI to improve, evolve, and elevate their personal and professional performance, and help us push the boundaries of what's possible in marketing and advertising. You don't need to be an AI specialist, but we value those who are already applying AI tools to work smarter — whether that's unlocking creative ideas, speeding up workflows, uncovering sharper insights, or finding new ways to drive performance. We love people who challenge the norm, ask "how can this be better?", and see AI as a tool to elevate the craft, not replace it.
