Senior Java Software Engineer

Senior Java Engineer | Cybersecurity | Amsterdam (Hybrid)

Salary: €90k–€110k

I’m working with a cybersecurity scale-up in the financial domain. The backend platform processes large volumes of sensitive data and runs continuously, so engineering quality, stability and scalability matter.

Off the back of a new strategic partnership in the financial services space, the platform is scaling up, with 2026 shaping up to be a busy year from an engineering point of view.

They’re hiring a Senior Java Engineer to work on the core backend services as the platform continues to evolve.

The work:

• Building and maintaining backend services in Java (Spring Boot)
• Working with event-driven systems and asynchronous processing
• Designing APIs used across the platform
• Improving performance, reliability and observability of services
• Working closely with product, data and infrastructure teams

The tooling/stack:

• Java, Spring Boot
• Event-driven architecture (Kafka-style systems)
• PostgreSQL
• Cloud environment
• Docker
• CI/CD pipelines
• Monitoring and logging as first-class concerns

What they’re after:

• Strong backend experience with Java
• Experience building and running distributed systems
• Comfortable working close to production
• Pragmatic, detail-oriented approach

The salary sits at €90k–€110k, with 25 holidays and 8% holiday pay included. The setup is hybrid, hours are flexible. Most importantly, you’re joining at a point where the platform is scaling, the work is getting more interesting, and 2026 is shaping up to be a big year from an engineering point of view.

We’re heading into the holidays now, so replies may be delayed by excessive food, too much alcohol, and poor self-control.
