  • Excellent knowledge of Java 8 & 17, including Streams, CompletableFuture, Records, Sealed Classes, Virtual Threads.

  • Experienced in microservices architecture and distributed systems with high concurrency.

  • Strong knowledge of cloud, Kubernetes, Docker, and CI/CD pipelines.

  • Passionate about functional programming, immutability, and clean code.

  • Great communicator with leadership skills and a proactive mindset.

What You’ll Get

  • Rate: €500–€550/day

  • 6-month contract with extension or permanent option after a few months

  • Based in Amsterdam, Netherlands (on-site/hybrid flexibility may apply)
