About us: 

We’re here to make money work for everyone and we're doing things differently. For too long, banking has been obtuse, complex and opaque.

We want to change that and build a bank with everyone, for everyone. Our amazing community suggests features, test the app and give us constant feedback so we can build something everyone loves.

We're focused on solving problems, rather than selling financial products. We want to make the world a better place and change people's lives through Monzo.

We are actively creating an equitable environment for all of our engineers to thrive.

Diversity and inclusion are a priority for us and we are making sure we have lots of support for all of our people to grow at Monzo.

About our Engineering Teams:

We have around 300 engineers out of roughly 2,500 people in total - and we have big ambitions. There are many interesting challenges ahead, and we're happy for people to move between teams or to specialise, whatever you prefer. As an engineer here you'd be able to work directly with anyone across the company, and we run regular knowledge-sharing sessions so you’ll learn heaps about everything from how banks work to effective communication.

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

What you’ll be working on: 

We rely heavily on the following tools and technologies:

  • Go to write our application code (there’s an excellent interactive Go tutorial here)
  • Cassandra for most persistent data storage
  • Kafka for our asynchronous message queue
  • Envoy Proxy for RPC
  • Kubernetes and Docker to schedule and run our services
