Java Software Engineer – Event Driven Platforms

Java Software Engineer – Event Driven Platforms (Kafka)

Zurich | Permanent | High-impact engineering For 37 years we have built software that sits at the heart of financial institutions. The kind of systems where reliability, traceability, and scale are not nice-to-haves, they are essential.

We are looking for a Java Software Engineer who has hands-on experience designing and building event-driven architectures, with Kafka as a core part of the platform, not an afterthought.

This role is about building and evolving the event backbone that drives complex, business-critical workflows across multiple services.

The engineering challengeYou will work on systems where a single event can trigger multiple downstream processes, such as compliance checks, enrichment, audit logging, and real-time decisioning.

The platform is built to handle high throughput, strict reliability requirements, and evolving business rules.

You will be expected to think beyond synchronous APIs and design systems that are:

Decoupled and scalable

Resilient to failure and easy to recover

Observable and traceable end-to-end

Kafka is used as the central nervous system of the platform, running in a modern cloud-native environment.

What you will be doing

Designing and implementing event-driven services in Java

Producing and consuming Kafka events that power core business workflows

Working with topics, partitions, and consumer groups to support scale

Handling real-world concerns such as retries, reprocessing, idempotency, and failure scenarios

Collaborating closely with other engineers and product teams on architectural decisions

Deploying and running services in a Kubernetes, Docker, Helm, and ArgoCD ecosystem

What we are looking for

Strong Java backend engineering experience

First-hand experience building Kafka-based event-driven systems in production

Solid understanding of event delivery semantics and failure handling

Confidence designing systems, not just implementing tickets A pragmatic, engineering-led mindset with a focus on quality and reliability

Nice to have

Kafka Streams or stream processing experience

Schema versioning or schema registry exposure

Experience with observability and monitoring in distributed systems

Familiarity with GitOps-style deployment workflows

Why Join

Complex, meaningful technical challenges A product-led engineering culture where architecture matters

Close collaboration across engineering, product, and the wider business The chance to work on systems that are genuinely critical to financial institutions

2 days a week on-site, 3 days work from home (Zurich)

If you are excited by event-driven thinking, enjoy solving hard backend problems, and want to build systems that scale cleanly over time, we would love to hear from you.
