Roles and Responsibilities

• Design, develop, and maintain Java-based enterprise applications and microservices using J2EE frameworks.
• Build and optimize RESTful APIs for distributed systems, ensuring scalability and high availability.
• Collaborate with architects and DevOps teams to design and deploy cloud-native solutions on AWS, Azure, or PCF.
• Develop and maintain database components—writing efficient, complex SQL queries on Oracle and integrating with NoSQL databases (e.g., Cassandra).
• Implement modern design principles (SOLID, DRY, SRP) to ensure clean, maintainable, and extensible codebases.
• Integrate and streamline data flow using NiFi, Kafka, NATS, Zookeeper, and related technologies.
• Utilize Redis and Cassandra for caching and distributed data storage.
• Monitor and troubleshoot application performance using tools like Splunk and application performance monitoring (APM) suites.
• Lead code reviews, performance tuning, and enforce engineering best practices across the team.
• Mentor junior developers and collaborate with QA, DevOps, and product teams to deliver end-to-end solutions.
• Identify and build common libraries/interfaces to simplify system interactions and improve development efficiency.

Required Skills & Experience

• 8+ years of hands-on Java development experience in J2EE and related frameworks.
• Strong expertise in microservices architecture and REST API design.
• Proficiency in Oracle SQL, PL/SQL, and experience with data-intensive systems.
• Proven experience deploying and maintaining applications in cloud platforms (AWS, Azure, or PCF).
• In-depth understanding of object-oriented principles, design patterns, and software architecture best practices.
• Familiarity with NiFi, NATS, Kafka, Zookeeper, Splunk, Redis, and Cassandra.
• Demonstrated experience with performance optimization and scalable system design.
• Strong problem-solving, analytical, and debugging skills.
• Excellent communication and leadership abilities with a proven record of collaboration across teams.

Preferred Qualifications

• Experience in containerized environments (Docker, Kubernetes).
• Exposure to CI/CD pipelines, Jenkins, and infrastructure as code tools.
• Knowledge of Spring Boot, Spring Cloud, and Reactive frameworks is a plus.
• Prior experience in enterprise-scale or fintech/cloud transformation projects.
