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
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 (andeveryone 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.).

The Omni Team's goal it to solve the multi-cluster multi-cloud Kubernetes challenge! Building on top of concepts from cluster federation it tries to shift the paradigm in Kubernetes usage patterns and how it is being used when many clouds are involved. And while doing this to enable CAST AI customers to realize significant AAA savings for our customers.
To give you a glimpse into the complexities we navigate:
We’ve successfully proven that you can do more with Kubernetes compute resources in the ways people didn't think was possible. We are building on top of giants, by leveraging OpenSource technologies like wireguard and controller-runtime. We write custom Kubernetes operators to orchestrate every component, related to multi-cluster operations in the clusters. Manage OpenSource project usage by maintaining stability, security, flexibility and independence. We strive for minimal APIs and user experience with the goal to make multi-cloud not only a buzzword, but reality. We're breaking new grounds of networking, Kubernetes operators and cloud provisioning at CAST AI. The above examples merely scratch the surface of what we've achieved. Consider that these efforts are magnified by the range of cloud providers we support - and each one presents its own unique challenges. Each development sprint uncovers new hurdles and learning opportunities. We consider ourselves fortunate to operate in a cutting edge technological landscape.
Here are some of the technologies we use in the stack: GoLang is our language. Kubernetes is our core product. AWS, GCP, and Azure are the clouds we operate. Postgres and cloud object storage for persistence. Temporal for our scheduling needs and executor. VirtualKubelet and ControllerRuntime for our operators stack. Terraform for IaC. GCP PubSub for messaging. GRPC and REST APIs. We use GitLab CI with ArgoCD as our GitOps CD engine. Prometheus, Grafana, Loki, and Tempo for observability. Deployment charts are written in Helm. Having experience with these tools is not a strict prerequisite for the ideal candidate, but it does offer a competitive edge.
