Java Backend Developer

We are seeking a highly skilled Java Developer with strong expertise in SQL and Apache Kafka, coupled with extensive experience in designing, developing, and deploying microservices architectures. The ideal candidate will excel at building scalable, high-performance data-driven solutions, leveraging Kafka for real-time messaging and data streaming, and integrating complex data systems with Java applications. Collaboration with cross-functional teams to drive innovation and maintain best practices is essential.

• Design, develop, and maintain Java-based microservices applications with a focus on efficient data processing and real-time messaging.
• Architect and implement robust data pipelines utilizing Kafka streams, topics, producers, and consumers to facilitate high-throughput, fault-tolerant data exchange.
• Develop complex SQL queries, stored procedures, and optimize database operations for relational databases.
• Seamlessly integrate microservices with Kafka messaging systems, ensuring reliable and secure message flow.
• Collaborate with product owners, architects, and other developers to create scalable solutions that leverage Kafka's capabilities.
• Build and consume RESTful APIs, and integrate with third-party services while ensuring data consistency and integrity.
• Utilize containerization (Docker) and orchestration tools like Kubernetes for deployment, scaling, and management of services.
• Write clean, well-documented code following best practices, emphasizing high-performance database interactions and messaging.
• Conduct code reviews, enforce coding standards, and maintain high-quality software.
• Troubleshoot and resolve production issues related to database performance, Kafka message delivery, and system reliability.
• Participate actively in Agile/Scrum teams, delivering features iteratively, with a focus on data and messaging architecture.
• Stay current with emerging technologies related to SQL, Kafka, microservices, and data streaming, incorporating best practices into development.

• Proven experience in Java development (Java 8 or higher) with a focus on data-intensive applications.
• Strong expertise in SQL, including complex query writing, database optimization, and stored procedures.
• Deep understanding of Apache Kafka architecture, including Kafka Streams, producer/consumer patterns, topic management, partitioning, and replication.
• Hands-on experience integrating Kafka with microservices for real-time data processing.
• Solid experience with microservices architecture design, RESTful APIs, and service-oriented development.
• Familiarity with Spring Boot, Spring Cloud, and related frameworks.
• Proficiency with containerization (Docker) and orchestration platforms (Kubernetes).
• Knowledge of relational (e.g., MySQL, PostgreSQL) and NoSQL databases as needed.
• Experience with DevOps practices, CI/CD pipelines (Jenkins, GitLab CI, etc.).
• Strong problem-solving skills, with the ability to diagnose and optimize database and messaging system performance.
• Excellent communication skills and ability to work effectively within a team.

• Experience with real-time data streaming and processing frameworks.
• Familiarity with message queuing systems like RabbitMQ (optional).
• Contributions to open-source Kafka projects or complex data pipeline implementations.
