Senior Java Developer - Malta · Jobs Europe AB

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.
