Senior Java Developer building the internal platforms that power iGaming operations in Malta — backend services and admin/back-office tools (configuration, content, reporting, workflows) using Java, Spring Boot, microservices, Kubernetes, cloud platforms, and PostgreSQL/MongoDB.
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.
