This August, as we were wrapping up the summer, Monzonauts across the business set out to learn from each other, have fun and build things centred around one theme: Monzo Magic. This activity is commonly referred to in the industry as a hackathon.

Sharing knowledge on how we implementing private networking between AWS and GCP

We wanted to share more about why we launched a new 0-1 product to help people pay for purchases later and how a mixed-method research discovery led to the product that over hundreds of thousands of customers use and love today!

If you’re starting out in a new role in research ops, design ops or any other kind of team operations, this blog will take you through the ins and outs of creating a flexible how-to guide database for scale.

We introduced automated rollbacks to our platform using Argo Rollouts and made it the default deployment strategy for all our services. This helps us roll out changes safely and catch a wide class of problems related to deploying new code

Since 2018, we've used Dep to manage our monorepo dependencies, but when it was deprecated switching to Go Modules was a high risk change. This post explains how we reduced that risk by iteratively updating our dependencies for a seamless migration.

Detective controls help us monitor our systems for unwanted behaviour, but since writing our first detection rules, our company and team has grown. This post explains how we scaled those detection rules using Sigma and have open sourced our tooling.

Kyle joined Monzo as a COp, a customer service representative, but three years on he now works in a product team as one of our backend engineers! Kyle and his mentor Duncan share the story of how Kyle made his career switch

We've been working on some new techniques to help make the development of services easier as we continue to grow and the entire platform can't be run locally.

We go into our mobile release process and how we're able to sustain a steady stream of releases as the changes that go into each version increase over time

With over 2000 microservices and lots of Remote Procedure Calls (RPCs) that are constantly changing, we needed a new way to manage staff access. The Security Platform team explain how we now define RPC permissions directly in proto files.

Izak joined Monzo as a data scientist in February. In this post, he shares his journey to Monzo and his early experience in the data discipline, with our data stack, and in the team looking after our Customer Operations.

Our success relies on us rapidly shipping new features. To achieve this rapid release cadence, we’ve optimised our engineering culture, tooling, and architecture to go from idea to production as frictionless as possible, without sacrificing safety.

Last year, I made the switch into engineering management full time. It’s been an interesting journey with lots of lessons learned.

Our Mobile Platform team recently faced the challenge of having to remove all synthetic view properties. This post explains how we built a tool to automate the task and the trade-offs we had to consider along the way.
