  • Build new microservices, APIs, and backend components to support application clients.
  • Design and implement database schemas and tables to handle large volumes of data.
  • Implement caching strategies to improve API and application performance.
  • Develop messaging-based integrations using Apache Kafka for asynchronous processing.

  • Ensure efficient data access for high-throughput, distributed systems.
  • Implement and maintain Kafka producers/consumers for inter-service communication.

Testing & Quality

  • Develop unit and functional tests using Spock and other testing frameworks.
  • Ensure high code quality through testing, reviews, and adherence to best practices.

Release & Operations

  • Work with Release Management to plan and execute microservice releases.
  • Create and manage release pipelines.
  • Deploy and validate release candidates in non-production environments.
  • Coordinate release and support activities with DevOps, Infrastructure, SRE, and Tier 1/2 support teams.
  • Support and maintain production microservices owned by the team.

Required Skills & Experience

  • 8+ years of experience developing Java applications.
  • 5+ years of experience developing backend web applications.
  • Expert knowledge of Java 11+, Spring Framework, and Spring libraries.
  • Strong experience with Spock for unit testing.
  • Very good understanding of Apache Cassandra, including data modeling and query patterns.
