OFFICE MANAGER (PART-TIME, 3 DAYS A WEEK)

READY TO DO WORK YOU’RE PROUD OF?

Run the office at one of London’s most ambitious independent agencies, three days a week. You don’t need the job title already. You need to be the person who’s naturally organised, gets things done and keeps everything running without being asked.

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? We blend data science and creativity to make smarter decisions and create work that makes an impact. The numbers give us clarity. Our creativity wins hearts, builds brands and drives growth.

Life at Charlie Oscar is fast-paced and full of chances to learn and grow. You’ll work alongside some of the sharpest minds in the industry, on work for global brands.

We make time for fun too. There’s weekly run club, book and chess clubs, charity fundraisers, Thursday drinks and team socials, so there’s always something to get involved in.

Most importantly, we hire for attitude and culture add, not just experience. We want curious, ambitious people who challenge the status quo, work hard and bring fresh ideas.

Sound like your kind of place?
