Implement data transformation using JAXB / Jackson for XML / JSON processing.
Ensure strong API security using OAuth2, JWT, API Keys, TLS / SSL, and threat-protection controls.
Perform unit testing using JUnit, especially for Camel-based flows.
Troubleshoot complex integration issues using Apigee debugging tools and ELK monitoring.
Own API lifecycle management, versioning, deployment, and performance optimization.
Provide technical leadership, conduct code reviews, and mentor junior developers.
Collaborate with cross-functional teams to deliver end-to-end microservices solutions.

Required Qualifications

5+ years of experience in Java, REST API development, and microservices.

Strong hands-on skills with Spring Boot, dependency injection, and configuration management.

2+ years of experience with Apigee (proxy creation, security, mediation, traffic management).

2+ years of experience with Apache Camel (route creation, DSL, components, error strategies).

Proficiency in Git, JUnit, XML / JSON transformation, and API debugging tools.

Understanding of GraphQL (nice to have).

Experience with ELK for logging / monitoring and secure API implementations.

Strong problem-solving, communication, and leadership skills.
