Office Manager & PA – Be the Heart of ARM

London

We’re looking for a stand-out Office Manager & PA to keep our agency running at its best. You’ll be the go-to person who keeps everything seamless, welcoming, and high-performing—supporting our people, leaders, clients, and partners every day.

This is your chance to shape an office where people feel supported, valued, and set up to succeed

Why ARM?

We’re one of the Europe’s leading performance media marketing agencies, with 130+ specialists across London, Amsterdam, and Leeds. We manage £250m+ in media spend and work with brands like Brooks, Omaze, Dusk, and Save The Children.

At ARM, you’ll get real ownership and a supportive, high-performing, inclusive culture. You will be working with the whole company – from the Senior Leadership Team through to new Execs.

✨ Make Your Mark

You build strong relationships, solve problems quickly, and constantly look for smarter ways to work. As the face of ARM, you’ll set the tone with warmth, care, and a genuine welcome for everyone. Just as importantly, you’ll help foster an inclusive, welcoming environment where everyone feels they belong—championing equality, diversity, and inclusion in how the office operates and how people experience it day to day.
