Site Reliability Engineer

London (UK)

Full Time

Wise is one the fastest growing companies in Europe and we’re on a mission: to make money without borders the new normal. We’ve got 10 million customers across the globe and we’re growing. Fast.


Current banking systems don't let us send, spend or receive money across borders easily. Or quickly. Or cheaply. 


So, we’re building a new one.


And we need a Site Reliability Engineer to join our mission and help us build a global platform that’s scalable, reliable and secure. 


Money without borders – instant, convenient, transparent and eventually free. During the 10 years since our launch, we helped millions of customers, but there are still customers who are suffering the most from the bank FX fees and need new, better banking tools to manage their money internationally. To address this need we launched a borderless account that is offering multi-country, cross-border banking in one app. Now we’re powering money for people and businesses: to pay, to get paid, to spend, in any currency, wherever you are, whatever you’re doing.The Wise card is a key part of the borderless proposition, it is responsible for the “spend” part of the general vision. Card issuing is the best way to let customers spend their money in the modern world, but we should keep in mind that real plastic cards are only one of a possible solution to spending problems. Tomorrow it could be digital cards, apple and google pays, QR codes, mobile payments, or something else that is not yet invented.


Here’s how you’ll be contributing to the Engineering Team

Spend & Cards are running more and more services within their PCI-DSS certified cardholder data environment, and the The Spend & Cards SRE team helps to ensure the CDE Kubernetes cluster is secure and sustainable, also helping to ensure all the services are running smoothly and efficiently. We are invested in AWS and Kubernetes, so we’re making the most of these abstractions. You'll also work with our product engineering teams to understand their needs and onboard them to new solutions.


Must Have


  • Experience with building out scalable and automated Cloud platforms on preferably AWS
  • Experience in infrastructure automation tools (Terraform/Ansible/Puppet/Chef)
  • Containerisation technology and various orchestration platforms e.g. Docker, Kubernetes
  • Experience with languages such as Java, Groovy, Python, Go etc
  • Basic sysadmin skills in debugging issues with disk, network, app/JVM performance etc
  • Will not settle at all for downtime and outages, do not want to be woken up in the middle of the night


Nice to Have


  • Good knowledge of relational (RDBMS) and NoSQL databases
  • Knowledge and an eye on newer architectural concepts such as microservices, service mesh, lambda programming
  • Network knowledge of DNS, network topology, switches, routers, 
  • Kubernetes ingress/egress, etc.


Key Areas of the role


  • Define and create standard operating procedures that are compliant and auditable
  • Ownership of mission-critical shared infrastructure - run, maintain and schedule upgrades
  • Isolation of environments and work with various engineering teams to figure out how to best suit their needs
  • Sees failover and DR events as something that needs to happen with regularity and should be seamless
