This blog talks about how we protect our workloads against supply chain attacks, specifically by achieving bit-by-bit reproducible builds, and how we have adopted Nix an alternative to Docker for build environments.

This post is an overview of how we leverage incremental modelling, a data transformation technique which helps us scale sustainably as we blast off to 10 million customers 🚀

When we launched our new Monzo home screen, Katherine spent the past year focused on designing, launching and analysing experiments to understand how customers reacted to their new app. This blog explains how she measured change aversion.

Drawing upon the wisdom and practices of our user research team at Monzo, this blog post captures ways to scale user research impact, craft effective goals, and define clear metrics.

I’m Grace, and I joined Monzo in October ’23 as a Backend Engineer in Fincrime Business Banking. I’m here to convince you to apply for that role you really want, and about how exciting, challenging and rewarding changing roles has been for me.

In 2022, we embarked on a long journey to move our main website. The whole process took us from June of 2022 to November of 2023, with plenty of fun curveballs along the way. Let’s dig into what it takes to migrate monzo.com.

This post delves into how Monzo is building on our product-led growth by adopting new growth design ways of working and how uniquely positioned design is as a business tool for growth. Buckle-up!

This post will explore how EMs at Monzo continue to leverage their software engineering backgrounds in practice, and how Monzo assesses those skills in our hiring process.

Customer segmentation is the art of dividing customers into useful groups, but there are a lot of pitfalls to avoid along the way. Here is Monzo’s guide to help you decide your segmentation approach, collect the right data, and more.

This blog covers core parts of the journey Constantign embarked on when he raised his first "small change" pull request, and how over time we have built a rich client library and set of abstractions that sit on top of Kafka

In this blog post, we explore how we built our home screen, a single stream of activity that lets you glance over the latest updates across all your bank accounts! Less searching around, less app-hopping, less confusion. 

We’ve shared the behind the scenes insights into how we wrote 5 million Years in Monzo, and the magic behind the data. Now we’re going to dig into how we turned this data into the Year in Monzo experience you know and love.

Monzo runs on a shared platform of infrastructure that hosts our microservices. In this post, we’ll discuss how we broker access to our infrastructure credentials with a system that is resistant to attacks even from the team that maintains it.

The Technical Programme Manager (TPM for short) role is hugely varied. I want to take you on a journey through a typical day in my life as a Technical Programme Manager here at Monzo.

This blog explores how we’ve made our platform more resilient to spikes in app opens. We can now reduce load on our platform before we get overwhelmed so you can still access and use critical parts of the app, and your card continues to work.
