About the Project: For our Client, a global leader in the online entertainment industry (iGaming), we are seeking an experienced Engineer to join the team in building the heart of a platform that engages millions of users.

This is not a typical "maintenance" project. You will join the User Experience & Loyalty Domain, where technology meets player psychology. You will be responsible for building advanced engines that drive user interactions – from real-time communication systems to complex bonus mechanisms and personalized loyalty programs.

Your Role:

  • End-to-End Ownership: Responsibility for the full software lifecycle – from concept to coding, deployment, and monitoring.
  • Technical Impact: Actively participating in architectural discussions, challenging the status quo, and proposing new technologies to optimize business solutions.
  • Scalability: Ensuring the IT ecosystem is scalable and ready for growing traffic and future market expansions.
  • Collaboration: Working closely with operational units and other technical domains to ensure a seamless "Player Journey".

Requirements (Must Haves):

  • Experience: Minimum 5+ years of commercial experience in backend development (Java and/or Kotlin).
  • Microservices: Deep practical knowledge of microservice architecture.
  • Messaging: Experience working with messaging systems (e.g., Kafka).
  • Frameworks: Strong knowledge of the Spring ecosystem and JPA.
  • Databases: Proficiency with relational databases (MySQL).
  • Mindset: Proactive approach, focus on "Clean Code," and willingness to take ownership of your initiatives.

Nice to haves:

  • Experience with OpenAPI 

    Experience with BigQuery 

    Experience with Kubernetes 

We Offer:

  • Work with state-of-the-art technology.
  • Real impact on key features of a globally used product.
