Wat houdt de functie in?
What does the role involve?
You will primarily write code and develop dependable backend services within a modern microservices landscape. Working from the Amsterdam area in a hybrid setup, you will contribute to the design, testing, deployment and continuous improvement of critical applications.
- You develop and maintain microservices and REST APIs using Java 21 and Spring Boot.
- You implement event-driven communication between services using Azure Event Hub and Kafka.
- You deploy and manage applications on Kubernetes, including Azure Kubernetes Service (AKS).
- You write automated tests with Testcontainers, WireMock, Mockito and MockMvc, including Kafka-based tests.
- You apply hexagonal architecture, SOLID principles and domain-driven design (DDD).
- You contribute to infrastructure as code using Terraform.
- You investigate issues involving communication, consistency, message ordering, retries, dead-letter queues and idempotency.
- You contribute to monitoring, deployment and rollback strategies within a team of six to eight developers.
- You share ideas, review solutions and take ownership of improvements from development through to deployment.
Who are we looking for?
You are a Medior Java Developer who enjoys hands-on engineering and is curious about how systems work beneath the surface. You work effectively on your own while actively collaborating with colleagues in a small team and contributing thoughtfully to technical decisions.
- You have bachelor’s or master’s-level thinking and several years of experience as a Java Developer at medior level.
- You have professional experience with Java, Spring Boot and building REST APIs.
- You have an affinity with event-driven systems such as Kafka and Azure Event Hub, including topics such as dead-letter queues, message retries, ordering and idempotency.
- You have knowledge of, or a genuine interest in, Kubernetes and AKS, microservices architecture, deployments and rollback strategies.
- You are curious about technical details such as Kafka serialisation and understand the practical challenges of distributed systems.
- You work independently, while deliberately seeking collaboration and sharing information within a small development team.
- You already have the right to work in the Netherlands or the European Union; visa sponsorship is not available for this role.
