Senior Backend Engineer (Java/Spring Boot)

Is there a Zenika in you?

Let’s talk skills and passion first.

You don’t just build back-end services — you design systems that are clean, resilient, and built to scale. You’re fluent in Java and Spring Boot, and you enjoy turning complex business needs into elegant APIs and microservices. You believe good architecture matters, tests are not optional, and performance is a feature.

You stay curious. Whether it’s exploring new frameworks, refining your understanding of distributed systems, or sharing ideas with peers, you’re always learning and levelling up your craft.
