Job Description

More about our mission and what we offer.

About The Role

We are looking for a senior software engineer with a background in using Apache Kafka.

Our Kafka team is part of the Data Squad.

We provide the tooling and infrastructure that allows Wise to use Kafka for messaging and stream processing. Our Kafka platform enables services to communicate asynchronously and pipelines to do calculations and make decisions in milliseconds, powering our validation, fraud detection and anti money laundering checks.

We also provide the tooling to manage our Kafka clusters and libraries for services to produce and consume data. This enables product teams to build their services focusing on the business logic instead of the Kafka infrastructure complexity.

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 Kafka team, we need to sustain this growth by continuously iterating on the services and infrastructure 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 Java And Using Kafka Clients, Being Able To Build And Support The Libraries We Use To Produce And Consume Data Asynchronously With Kafka. Some Of The Technologies We Use

• Java, Python
• Spring
• Terraform
• AWS
