At Monzo we’re aiming to build the . We are always keen to hear from capable, creative engineers who want to help us accomplish that goal 🚀
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 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 as much as possible. We’ve also made our public and give sneak peeks of features in our . Our is a good place to learn even more about what we do!
Monzo works in project-based sprints in small, interdisciplinary teams
We’re still a relatively small company, with around 60 engineers out of roughly 300 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:
to write our application code (there’s an excellent interactive Go tutorial )
for most persistent data storage
for our asynchronous message queue
/ for RPC
and to schedule and run our services (, our Head of Engineering, gave a great at KubeCon on how we use these technologies)
for most of our infrastructure
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:
Scaling Customer Operations
Monzo is a customer service company. In order to scale our current level of service to a billion users and beyond, we are investing heavily in building a state of the art workflow management system for all manual work in the company. We consider this to be our secret competitive advantage that is not really visible outside the company. You can read more about this team in this (we’ve changed team names since this was written - the team making these tools used to be called "Internal Product").
Help us take Monzo’s data capabilities to the next level by building systems which allow us to explore massive data sets interactively and run machine learning models in real time on event streams, all whilst maintaining strong data integrity. If you are interested in how we think about data and analytics and would like to read more, take a look at .
Help us build a state-of-the-art microservices platform based on the learnings of Netflix, Twitter, and Google. We're investing a lot of up-front effort in building a scalable, secure, and extensible architecture. We've posted a good overview of our platform on our .
Help us write code that moves money. Between integrating with crufty old payment schemes, connecting to legacy systems from the 1970s, and designing our own core banking ledger, at Monzo we get to see how the financial sausage is made! If you were ever curious about how money flows through the financial systems or wanted to write code to move money in a safe way, this is your chance.
Over the first 9 months of 2017, we organically grew our user base almost 5% week-over-week. This growth was the result of several new features we introduced under the umbrella of "Monzo with friends". The Growth team is a full-stack product engineering team that is responsible for building product features that drive growth.
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).
Our long term goal is to be more than just a bank - we want to become each user's . The revenue team is building integrations and product features that help our users save money or otherwise optimise their financial life. They also build fair and transparent lending products. In the short term, our primary revenue stream comes from lending. We have written a to give you an idea of what that looks like.
Financial Crime and Security
We do a lot of work around fraud and electronic crime, using a mix of machine learning models, discrete rules, human review, and clever product features to fight back. We've written about how we do that on our . You’d work closely with our Risk and Compliance team, analytics, customer support, and fraud investigators to make sure we’re doing everything we can to fight against financial crime.
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 test, 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
If you’re unsure about applying or have any questions about the role or team, please don’t hesitate to email or directly Also, if you are under time pressure to change jobs soon (or have any other deadlines), please let either of them know, as we will always do our best to speed up the process for you!
