Engineering at Monzo

We have 500+ engineers across Monzo who design and build our in-house banking platform. We have big ambitions for the future, and technology plays a big role in creating a bank our customers want, so engineers at Monzo 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, to name just a few areas. As a bank, there is scope for impact across a huge number of opportunities.

We contribute to open source software as much as possible. Our blog is a good place to learn even more about what we do.

Engineering Interns

As a software engineer intern at Monzo, you’ll be matched with a team where you’ll spend the summer working on a real project for our customers. We’ll pair you with a mentor who will support you to design and ship a solution to solve a real problem.

You’ll have the opportunity to work alongside engineers to learn more about software engineering and the types of challenges engineers at Monzo solve on a day-to-day basis.

• AWS for most of our production infrastructure and GCP for most of our data infrastructure
