Your Role

As a Java Engineer you will design, build, and operate scalable backend systems using modern Java and widely adopted open‑source frameworks. The role focuses on delivering robust, maintainable, and secure services that support business-critical platforms, while actively leveraging and contributing to the open-source ecosystem.

You will work close to the core of the technology stack, collaborating with other engineers, architects, and product stakeholders to translate business needs into well-structured, production-ready solutions. The role values clean code, thoughtful design, and long-term sustainability over short-term fixes, with a strong emphasis on observability, testing, and operational excellence.

Open source is a key part of how solutions are built: from using mature frameworks such as Spring or Quarkus, to evaluating libraries, understanding licensing implications, and contributing improvements back to the community where appropriate.

In this role you will play a key role in

• Designing, developing, and maintaining backend services and APIs using Java and JVM‑based technologies, while applying solid software design principles such as clean architecture and domain‑driven design to build well‑structured and maintainable systems.
• Building reliable and scalable backend solutions, including both RESTful and event‑driven services. You will work with relational and non‑relational databases to design schemas, optimize queries, and ensure data consistency and transactional integrity.
• Ensuring that services are production‑ready by implementing automated testing at multiple levels (unit, integration, contract) and by establishing effective logging, monitoring, tracing, and alerting to support stable operations.
• Contributing to overall engineering quality by participating in code reviews, architecture discussions, and technical decision‑making. You will support DevOps practices including CI/CD pipelines, containerization, and cloud or Kubernetes deployments, while managing open‑source dependencies responsibly and securely.

Your Profile

• Strong experience with Java and a solid understanding of the JVM, including concurrency and memory management.
• Hands-on experience with open‑source Java frameworks such as Spring Boot, Spring Data and hands on experience with Kafka and Elasticsearch.
• Practical experience with automated testing using JUnit and Groovy/Spock, and working knowledge of DevOps practices including Git, Maven/Gradle, Docker, and CI/CD pipelines.
• Strong problem‑solving skills, attention to detail, and the ability to communicate technical concepts clearly.
