Staff Engineer - Data Platform
At Monzo we’re aiming to build the control centre for peoples financial lives. We are always keen to hear from capable, creative engineers who want to help us accomplish that goal 🚀
We’re here to make money work for everyone and we're doing things differently. For too long, banking has been obtuse, complex and opaque.
We want to change that and build a bank with everyone, for everyone. Our amazing community suggests features, test the app and give us constant feedback so we can build something everyone loves.
We're focused on solving problems, rather than selling financial products. We want to make the world a better place and change people's lives through Monzo.
About our Engineering Teams:
We have around 300 engineers out of roughly 2,000 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.
What you’ll be using/What you’ll be working on:
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
- 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

- Rally your team around a mission, objective or company priority, injecting urgency when needed or slowing down pace to make sure the right controls are in place
- Understand several work-streams across your group keeping enough context to regularly provide technical advice to other engineers
- Use your expert knowledge and experience to lead architectural discussions for the most complex systems in the collective. You’ll do this in order to arrive at solutions that are robust and optimal given the context
