Develop and maintain UI components using JSF (PrimeFaces), with optional contributions to Angular-based front-end projects.

Ensure application security, performance, and scalability using industry best practices.

Utilize Bitbucket (Git) for source control, JIRA for Agile task management, and Maven for dependency management and build automation.

Lead code reviews, architecture discussions, and best-practice implementations.

Troubleshoot production issues, ensuring system stability and performance.

Leadership & Team Management

Lead and manage a team of developers, ensuring best practices are followed.

Conduct mentorship and training sessions for junior developers to improve overall team proficiency.

Organize knowledge transfer sessions on Java, Spring Boot, GraphQL, and software design patterns.

Collaborate with cross-functional teams including business analysts, UI/UX designers, and DevOps teams.

Guide the team through Agile methodologies, Sprint Planning, and Scrum practices.

Required Qualifications

5+ years of experience in Java development with strong expertise in Spring Boot.

Hands-on experience with GraphQL API and RESTful Web Services development and optimization.

Strong experience in JPA/Hibernate for ORM and database interaction.

Proficiency in MSSQL and MySQL, with strong database performance tuning skills.

Knowledge of Angular (optional but a plus).

Experience with Bitbucket (Git) for source control and JIRA for Agile project tracking.

Strong knowledge of Maven for dependency management and build automation.

Proven experience in leading development teams, mentoring junior developers, and conducting knowledge-sharing sessions.

Strong understanding of RESTful APIs, GraphQL, and microservices architecture.

Excellent problem-solving and debugging skills.
