Feature Engineer; L3

Location: While our offices are in Bristol and London, we welcome remote applicants based in the UK. Attendance at our Bristol office will be required once a month or as needed.

At Bunch, we believe managing your home bills should take minutes — not months of chasing. So we’ve built the smartest way to handle shared household costs, starting with a single fixed monthly payment that covers everything from energy to broadband to water. No more awkward money chats. No more missed due dates. No more stress.

We exist to give people back their time, their headspace, and a bit of sanity. Because in a world that’s always on, admin shouldn’t be another full-time job.

We’re a fast-growing team with a rebellious streak. We challenge the way things have always been done and ask: how can this be smarter, easier, better for the customer?

We’re looking for people who are bold, human, and obsessed with making things simpler. People who thrive in fast-paced environments, love solving real-world problems, and care deeply about the impact their work has.

Sound like you? Join the Bunch Crew.
