About the role
We’re on a mission to back the UK’s small businesses like no one else. Small businesses are the backbone of the economy, and we’re here to help them win.

It’s a unique mix that gives Circlers the autonomy to take ownership and the scale to make an impact that truly counts. We’re a high‑performing team that chooses to lift each other up. We challenge, we champion, and we have each other’s backs — because we know that when we stand together, we move faster and build better. Last year alone, the businesses on our platform generated £7.2bn for the UK economy.
