At Monzo we’re aiming to build the best current account in the world. We are always keen to hear from capable, creative engineers who want to help us accomplish that goal 🚀

Please note: we get lots of successful applications for Backend Engineer, so there could be a delay in scheduling interviews from the initial stage right up until the final interviews. If you're invited to interview and you have any immediate time pressures, please let us know, as we'll always do our best to speed things up for you 😊

Our backend engineers have a variety of different backgrounds

We have several non-graduates; only some of us studied Computer Science; one of the team has a degree in Marketing; some of us have worked in huge companies; some have only ever worked in startups; others are former consultants. As long as you enjoy learning new things, we’d love to talk to you. 

We encourage an open and transparent working environment

You can get involved in any aspect of the business you are interested in and, following Stripe’s example, all emails in the company are visible in an email archive. We regularly run hackathons in which people build things on our third party API and we contribute to open source software as much as possible. We’ve also made our product roadmap public and give sneak peeks of features in our community forum. Our blog is a good place to learn even more about what we do!

Monzo works in project-based sprints in small, interdisciplinary teams

We have around 150 engineers out of roughly 750 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. 

At Monzo you will get to work with a lot of exciting new technology.

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 (Oliver, our Head of Engineering, gave a great talk at KubeCon on how we use these technologies)
  • AWS for most of our infrastructure
  • React for internal web dashboards
  • We also have two physical datacenter sites with actual cables to connect to various third parties

You should apply if:

  • the work we’re doing sounds exciting!
  • you want to be involved in building a product that you (and everyone you know) use every day
  • you’re keen to learn more about new technologies and the arcane inner workings of the financial industry
  • you’re comfortable working in a team that deals with ambiguity
  • you’re interested in distributed systems and writing resilient software
  • you have some experience with strongly-typed languages (Go, Java, C, Scala etc.).

At the moment, the following teams are looking for backend engineers: 

Product
The product backend team work primarily on creating backend services and APIs for our in-app user-facing features. They work closely with our mobile engineers and designers to create a delightful user experience, and to drive growth and retention. Projects that Product backend engineers have worked on recently include Summary (giving people insight into their finances to empower them to spend sensibly) and the Current Account Switch Service (all the hard work to allow users to move to Monzo quickly and easily).

Lending
The Lending team works on making borrowing money simple, fair and transparent. They've already shipped and scaled overdrafts to hundreds of thousands of Monzo customers and they've made it easy to take out a loan without the unfair fees or confusing pricing that you find elsewhere. They work on everything from the way borrowing works in the app, right down to how they move and account for money that our customers borrow. One of the most interesting problems they face is deciding how much to lend and to whom. The team believes that they can make access to credit fairer and more transparent.

Logistics

We can help you relocate to London, we can sponsor visas, and we're open to remote working (as long as you can spend around 20% of your time in London).  

We offer competitive salaries based on skills and experience, which could be anywhere between £40,000 - £100,000 per year. 

We care deeply about inclusive working practices and diverse teams. If you’d prefer to work part-time or as a job-share, we’ll facilitate this wherever we can - whether to help you meet other commitments or to help you strike a great work-life balance.

We’re continually hiring for Backend Engineers! Our interview process typically consists of an initial phone screen, a take-home code task, and a half-day on-site interview. We promise not to ask you any brain teasers or trick questions, and we won't make you code on a whiteboard
