Posted 3 weeks ago

TransferWise 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 8 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’re looking for a Site Reliability Engineer to join us to work with the Web guild and various product-facing teams on our growing fleet of node.js microservices.

For our customers, using TransferWise should feel as simple as sending a text message. Yet behind our app and website lies a complex, one-of-a-kind engine of currencies and routes that’s being designed, built and powered by our talented teams in cities around the world. With new capabilities being built every day, there’s still a lot to figure out, and we can’t do it alone. This role is a unique opportunity to have an impact on TransferWise’s mission, grow as a product leader and help save millions more people money.  

Our SRE team is responsible for building the runtime framework and libraries, which ensure microservices run in a robust and resilient manner. We want to deliver sustainable solutions for product teams, with a healthy dose of paranoia knowing how complex, distributed systems can fail.

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

  • You will be working hands on as an SRE, but embedded with the product teams that are building brilliant user experiences for customers. The JS engineers work in different teams, but meet frequently together as the Web guild, to collaborate around certain common problems they may have. We want to ensure that anyone using TransferWise receives a fast, consistent, reliable and accessible experience, throughout all of our products.
  • We expect knowledge and interest in the node.js services and ecosystem, especially as it scales. Knowing the ins and outs of Web technologies and how content gets delivered to a customer’s browser is key - we are always looking to evolve. Testing, automation and monitoring is fundamental, so we deliver quality and make data-driven decisions when it comes to technology and changes.

Is that you?

  • Experience or interest in node.js, backend services written in JS
  • Understanding of client-side and server-side rendering, the role of middleware and frameworks like next.js
  • Knowledge of Web protocols and technologies (HTTP, DNS, CDNs) that power the Internet
  • Experience with monitoring and observability tooling, especially focused on customer experience end-to-end
  • Understanding of distributed systems, scalability and tradeoffs when it comes to consistency and availability
  • 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

  • Security of js/node.js - OWASP, vulnerabilities, injection attacks, package management
  • Containerisation technology and various orchestration platforms e.g. Docker, Kubernetes
  • Knowledge and an eye on newer architectural concepts such as microservices, service mesh, backend-for-frontend, GraphQL
  • Basic sysadmin skills in debugging issues with disk, network, app/JVM performance etc

Key Areas of the role;

  • Collaboration and working with multiple product engineering teams
  • Understand how failure modes, graceful degradation and failover should happen. Events like these should happen with regularity and should be seamless
  • Engage regularly with our blameless postmortem culture, always focused on continuous improvement

And because we believe that diverse teams build better products, we’d especially love to hear from you if you’re from an under-represented demographic.
