Cloud & Messaging Solutions: Implement asynchronous and event-driven messaging solutions leveraging Spring Integration, JMS, AMQP, and REST APIs within Microsoft Azure integration environments.

System Analysis & Modeling: Gather technical requirements, translate business needs into system specifications, and construct UML design models, use cases, and solution prototypes.

Team Leadership & Technical Guidance: Serve as Team Lead, mentoring developers, directing technical task execution, facilitating design discussions, and reviewing code and architecture artifacts.

Performance & Governance: Conduct system performance assessments, capacity evaluations, and risk analyses while ensuring solutions adhere to enterprise security, recovery, and architecture standards.

Qualifications
Backend Design Seniority: 10+ years of hands-on backend design and development experience using REST Web Services, JPA, Hibernate, relational databases, SQL, and PL/SQL (Strictly Required).

Technical Team Leadership: Proven experience acting as a Team Lead, facilitating technical discussions, and directing development teams (Strictly Required).
