Ravelin is looking for a senior backend engineer to lead the development of a high volume fraud technology platform within a small tech team. You will be invited and expected to have opinions about the strategic direction of the company and products, as well as leading the development team from the front. A successful candidate will be willing learning new skills (machine learning, neural networks, python, golang, cloud automation etc), turning their hand to necessary tasks and working with complete autonomy.
Code for Humans
Your machine is happy if it compiles; your team is happy if they can understand what it does. Your pull requests are succinct and a pleasure to review, you have unit tests where it matters, and you understand that the code is not, in fact, the documentation.
Reliable & Resilient Software Not for you the happy path or the assumed network. That habit of yours of assuming the worst and planning for it has earned your stripes in the world of running software at scale under real-world conditions.
Tools for the Team
Whether it's a smart command line utility or a core internal library, you excel at improving everyone's lives by removing repetition & common sources of error, and by solving hard problems in accessible ways. You build internal processes that are so reliable they melt into the background but are key to getting work done.
APIs
You've been on the receiving end of APIs good and bad, and want to delight our customers with the high quality they expect. You know that whilst everything should be JSON, sometimes you have to get your hands dirty with some SOAP for that critical integration but know how to isolate the contagion.
We are an equal opportunity employer and value diversity in our company. We do not discriminate on the basis of race, religion, colour, national origin, gender, sexual orientation, age, marital status, or disability status.
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 ourproduct 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’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:
Go to write our application code (there’s an excellent interactive Go tutorial here)

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
