Software Engineer – Connect

Engineering, London





Salary (annual)

60,000 - 80,000 GBP + benefits

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 16 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.

About the role 

We are looking for a Software Engineer with a service mesh focus to join our core service connectivity team.

Our team develops and operates Wise’s Envoy-based service mesh on top of Kubernetes (instrumented by our custom Java-based control plane), as well as our core ingress and egress pipelines (built on Cloudflare and various proxy software). Other teams build on these so hundreds of distributed microservices can communicate reliably and securely with each other, and also handle incoming requests from users or reach third-party services.

How we work

We operate on a strong belief in automation, programmatic implementation, and reusable design. We’re looking for people who can step back and think holistically about the ecosystem, but also follow through and help implement the design; drawing on the resources across the rest of the platform tribe.

As we grow, the demand for creating and connecting new environments grows as well, and use-cases get more complex. We need to sustain this growth by continuously iterating on the services we run, with a focus on availability, security, and ease of use. We’re looking for an engineer with relevant experience who can analyse complex requirements and deliver simple solutions to help our teams achieve our mission with speed and confidence. 

You will, together with us

  • Extend our service mesh to various workloads across diverse environments
  • Develop our Java-based mesh control plane further
  • Rebuild our ingress and egress pipelines using reliable L4 and L7 proxies
  • Contribute upstream to the Envoy project
  • Participate in a team on-call rotation

Desirable Knowledge

  • Proficiency in Java coding, testing and production aspects
  • Reading familiarity with Golang and/or C++ (writing won’t hurt either!)
  • Kubernetes microservices and networking experience
  • Networking protocols from L3 to L7 & application-level concerns.
  • Troubleshooting system & networking troubles on the Linux command line

Nice to have

  • Operating reliable software-based L4 and L7 proxies (e.g. Envoy, Nginx)
  • eBPF-based packet filtering and tooling experience
  • Familiarity with transport layer security and certificate management

We expect that you…

  • … work efficiently in a team to bring projects to completion
  • … are a strong communicator, written and verbal
  • … feel drive to automate manual operations
  • … think about risks, security and reliability
  • … are open to both mentoring others as well as learning from them
  • … look for opportunity to add impact and challenge the norm

What you get back:

  • 🚀 RSU’s in a growing company 
  • 💪 An annual self-development budget
  • ❤️ Statutory maternity leave, with a perk of 18 fully paid weeks of parental leave for birth or adoption
  • ❤️Paternity leave for 18 weeks at full pay
  • 🌿3 fully paid ‘me days’ per year to help you manage life
  • 🏝️ A paid 6-week sabbatical leave after four years

Salary: £60,000-£80,000 + RSU
