We're looking for a Senior Server Engineer to join our team of top-tier developers responsible for designing and building the backbone of High 5 Games' products and platform. In this role, you'll work on cutting-edge server-side technology, leveraging cloud infrastructure, big data, and AI to deliver scalable and high-performance systems that power some of the most engaging social casino experiences in the world.

You'll be a key contributor in designing and delivering all H5G server systems, services, and data stores — helping drive our platform to the next level of performance and reliability.


What You'll Do:

Architecture & Systems Development

  • Design, develop, and optimize highly scalable Java-based backend systems and microservices.
  • Build and maintain real-time, high-throughput architectures using Spring Boot (2.5+), REST APIs, Tomcat, Kubernetes, and the Docker ecosystem.
  • Design and deliver high-volume, highly available back-end infrastructures (20K+ mps) leveraging Kafka and Hazelcast.
  • Apply distributed system concepts such as leadership, consensus, partitioning, and replication to ensure scalability and resilience.
  • Conduct performance analysis and optimization across databases, application code, and infrastructure layers.
  • Develop comprehensive testing strategies (TDD, BDD) and ensure code reliability through robust unit, integration, and system tests.
  • Identify, diagnose, and resolve complex production issues with strong debugging and troubleshooting skills.

Data Management

  • Work with both SQL and NoSQL databases, particularly Cassandra and MySQL.
  • Utilize cloud-based big data tools for data processing and analysis.
  • Implement real-time stream analysis and contribute to machine learning (ML) and AI modeling initiatives where applicable.

Operational Excellence

  • Build operationally mature systems that are scalable, secure, and well-instrumented.
  • Use tools like Gradle, Jenkins, Nexus, GCP, Kubernetes, Docker, and Datadog for CI/CD, monitoring, and deployment.
  • Apply SDLC best practices and ensure code quality, documentation, and smooth delivery pipelines.
  • Collaborate using Jira, Confluence, and other tools to maintain alignment across teams.


What We're Looking For

  • 6+ years of hands-on experience in Java server-side development, ideally with Java 11/17+.
  • Proven background in building and scaling real-time, high-availability back-end systems (Telcos, Trading, AdTech, or similar).
  • Strong expertise in microservices architecture, REST API design, and Spring Boot.
  • Deep understanding of distributed systems, security concepts, and enterprise architecture.
  • Experience in Kafka, Hazelcast, Cassandra, and MySQL.
  • Familiarity with GCP, Kubernetes, Docker, and monitoring tools like Datadog or Stackdriver.
  • Exposure to machine learning, AI modeling, or streaming data is a plus.
  • Excellent communication, collaboration, and problem-solving skills.
  • A passion for staying up-to-date with the latest in server, cloud, and Java technologies.


Education

  • Bachelor's degree in Computer Science, Engineering, or a related field required.
  • Master's degree (MS in CS or Engineering) is a plus.
