Senior Java Developer - Malta
Jobs Europe AB · Tills vidare · Deadline 2026-11-05
Jobs Europe AB is hiring a **Senior Java Developer - Malta** to design and build internal platforms powering iGaming operations, including studio tools, configuration systems, back-office administration, and operational workflows. Working closely with product, QA, and DevOps teams, the role involves building scalable microservices and APIs with Spring Boot, deploying and operating services on **Kubernetes**, and implementing cloud-native architectures across AWS, Azure, or GCP. Responsibilities also cover event-driven and REST communication, real-time UI updates via WebSockets or SSE, database design and performance tuning with PostgreSQL and MongoDB, robust system security, and setting up observability tools for production troubleshooting. Applicants should hold a **bachelor’s or master’s degree in Computer Science or equivalent practical experience**, supported by proven backend engineering experience with Java and Spring or Spring Boot. The position requires a solid understanding of distributed systems, microservices, and API design, along with hands-on experience using Docker, Kubernetes, and relational or NoSQL databases. Candidates must also demonstrate familiarity with major cloud platforms, CI/CD pipelines, automated testing, backend security practices, and have an interest in developing robust platforms for the iGaming sector.
Role Description
As a Java Developer, you will help design and build the internal platforms that power iGaming operations—such as studio tools, configuration and content management, operator/admin back-office services, reporting, integrations, and operational workflows. This role suits engineers who enjoy ownership, building reliable services, and collaborating closely with product and operations stakeholders in a fast-moving environment
Key Responsibilities
- Design and develop backend services using Java and Spring Boot, delivering reliable, maintainable APIs for internal platforms and admin tools.
- Build and evolve a scalable microservices architecture for back-office domains (configuration, users/roles, content/admin, audit, reporting, workflow automation).
- Deploy and operate services on Kubernetes, focusing on availability, scalability, and resource efficiency.
- Use cloud platforms (AWS/Azure/GCP) to build and run cloud-native services, including storage, networking, and managed services where appropriate.
- Implement service-to-service communication patterns (REST/event-driven), and when needed support real-time updates for admin/studio UIs (e.g., WebSockets/SSE).
- Design and manage data persistence using PostgreSQL and/or MongoDB, including schema design, migrations, indexing, and performance tuning.
- Apply security best practices: authentication/authorization (RBAC), secure API design, secrets management, audit trails, and data protection.
- Write unit/integration tests, participate in code reviews, and continuously improve reliability and performance.
- Set up and maintain observability (structured logging, metrics, tracing, alerting) and support production troubleshooting.
- Collaborate with cross-functional teams (product, QA, DevOps/SRE, operations) to deliver features end-to-end and maintain clear technical documentation.
Requirements
- Bachelor’s or Master’s degree in Computer Science or equivalent practical experience.
- Proven backend development experience with Java and Spring Boot/Spring.
- Strong understanding of microservices, API design, and distributed systems fundamentals.
- Hands-on experience with Docker/Kubernetes.
- Familiarity with cloud platforms (AWS/Azure/GCP) and cloud-native patterns.
- Solid experience with SQL and/or NoSQL databases (PostgreSQL, MongoDB) and performance considerations.
- Strong grasp of security in backend systems (authn/authz, OWASP-style risks, data protection).
- Experience with CI/CD, automated testing, and release best practices.
- Strong debugging/problem-solving skills; clear communication and teamwork.
- Interest in building robust internal platforms within iGaming.
