· Act as a Subject Matter Expert (SME): Serve as a go-to expert for Java development, advising senior stakeholders and team members on best practices, architectural decisions, and complex technical challenges.

· Drive System Improvements: Analyze complex problems, evaluate business and system processes against industry standards, and make evaluative judgments to recommend and implement improvements.

· Ensure Security & Compliance: Recommend and develop security measures in post-implementation analysis and ensure all solutions comply with applicable laws, rules, and regulations.

Development & Implementation

· End-to-End Ownership: Monitor and control all phases of the development process, including analysis, design, construction, testing, and implementation.

· Build & Maintain Applications: Develop, test, and deploy new or revised applications to meet specific business needs and user requirements.

· Provide Technical Support: Offer user and operational support on applications, and consult with users, clients, and other technology groups to resolve issues and recommend advanced programming solutions.

· Define Standards: Ensure essential procedures are followed and contribute to defining and refining operating standards and processes for the development team.

Mentorship & Collaboration

· Coach & Mentor: Serve as an advisor and coach to new or junior developers, helping them grow their skills and careers.

· Collaborate Across Teams: Work closely with business users, product owners, and other technology teams to ensure alignment and successful project delivery.

Required Qualifications & Skills

· Experience: 5+ years of professional Java development experience, with substantial exposure to cloud-based environments and distributed systems.

· Core Java Expertise: Expert-level command of Java, J2EE, RESTful API design, and cloud engineering principles.

· Frameworks: Hands-on experience building production-grade services using Spring and Spring Boot.

· Databases: Solid database experience with relational systems (e.g., Oracle, SQL) and familiarity with NoSQL technologies (e.g., MongoDB).

· Cloud & Messaging: Practical experience with cloud-native platforms like OpenShift and Kubernetes, and messaging technologies such as MQ and Kafka.

· Software Craftsmanship: A deep commitment to clean code principles, design patterns, and test-driven development (TDD) practices that produce maintainable, production-ready software.

· Agile & DevOps: Fluency in Agile methodologies and the full software development lifecycle, with hands-on experience building and maintaining CI/CD pipelines.

· Leadership: Demonstrated ability to lead technical delivery autonomously, manage competing priorities, and perform effectively under pressure in a fast-paced environment.

Education

· Bachelor’s degree/University degree in Computer Science, Engineering, or a related field, or equivalent professional experience.
