Senior Software Engineer – Stream Processing

Engineering, Tallinn





Salary (annual)

64,000 - 88,000 EUR + 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.

We need a Senior Software Engineer  to join our mission and help us build a global platform that’s scalable, reliable and secure. You’ll dive right into projects on our stream processing infrastructure.

About the role 

We are looking for a senior software engineer with a background in stream processing.

Our team is called Realtime Data Platform and it’s part of the Data Squad.

We provide the tooling and infrastructure that allows Wise to process transfers in real time. Our stream processing platform enables services to do calculations and make decisions in milliseconds, powering our validation, fraud detection and anti money laundering checks.

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.

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. 

What will you be working on?

You’ll be working hands on designing, architecting, implementing and operating our systems on AWS. In addition, you will also help our product engineers use our tooling and systems, laying down best practises and rules. You should have a deep understanding of stream processing and the related technologies, being able to build and support the tooling to create pipelines that are used for real time decision making in the milliseconds range.

What do you need?

  • Experience with Kafka Streams and/or Flink.
  • Experience building production code with Java and Spring.
  • Experience with infrastructure automation tools.
  • Experience building and operating distributed systems at scale.

Nice to have:

  • Knowledge of Kafka, ZooKeeper and their operations.
  • Experience with Kubernetes and infrastructure integrations.
  • Experience with Terraform, Atlantis.

You get back:

  • The ability to choose your own path to success – you’ll have the freedom to define the vision 
  • The freedom to have real impact
  • The opportunity to inspire teams 
  • A fun work environment with social activities and events
