About Our Engineering Teams
We have over 400 engineers across Monzo who design and build our in‑house banking platform. We have big ambitions and technology plays a big role in creating a bank our customers want, so engineers collaborate across disciplines to solve interesting challenges throughout the company. These range from the products our customers use everyday to underlying infrastructure, security, payments and finance, customer operations, financial crime, and data.

Your day‑to‑day
This role is all about collaborating with your team to make a difference to your customers. As a backend engineer you’ll work in a squad alongside product managers, marketers, user researchers, designers, mobile engineers, web engineers, data analysts, business analysts, writers and more. Together you’ll build and support a particular part of Monzo. Our squads belong to our wider collectives (a word we use to describe self‑governing business units of ~100 people). They include Core Banking, Business Banking, Wealth, Borrowing, Growth, Payments, Platform, Fincrime, Security & Expansion.
