Job description
Company Description

Wise is a global technology company, building the best way to move and manage the world’s money.

Min fees. Max ease. Full speed.

Whether people and businesses are sending money to another country, spending abroad, or making and receiving international payments, Wise is on a mission to make their lives easier and save them money.

Job Description
About the role

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

Our Stream Processing team is 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.

We also provide the services responsible for data movement into our data lake. This enables product teams and analysts to make data driven decisions.

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 Stream Processing team, 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. Some of the technologies we use :

  • Kafka Streams
  • Apache Flink
  • Apache Iceberg
  • K8s operators
What do you need?

We are fully aware that it is uncommon for a candidate to have all skills required and we fully support everyone in learning new skills with us. So if you have some of those listed below and are eager to learn more we do want to hear from you!

  • 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.
