• Refactor traditional monolithic structures into modular microservices using modern integration strategies and emerging enterprise services.
• Collaborate with cross‑functional engineering teams to ensure smooth integration of new services following industry best practices.
• Develop and maintain software components using Java (Java 8 and Java 21), utilizing technologies such as JSP, JSTL, CDI, and Spring alongside a responsive user interface that leverages Bootstrap, CSS, SCSS, JavaScript, and JQuery.
• Implement new architecture by leveraging Golang‑based services and Angular for a modernized front‑end experience.
• Document technical designs, system integration requirements, and transition processes in support of ongoing and future initiatives.

Responsibilities

• Take ownership of large sections of the system architecture while working collaboratively with teams.
• Drive agile development practices and support robust continuous integration/continuous delivery (CI/CD) pipelines.
• Clearly articulate complex system designs and technical concepts to both technical and non‑technical stakeholders.
• Oversee the evolution of the software process from development through deployment, ensuring efficient and secure code integration.
• Engage in continuous process improvement to enhance software quality, performance, and reliability.

Required Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, or a related technical field.
• 5+ years of hands‑on software engineering experience.
• Proficiency in Java development (Java 8 and Java 21) with expertise in JSP, JSTL, CDI, and Spring frameworks.
• Proven experience in maintaining and modernizing web applications, particularly within Tomcat and Kubernetes environments.
• Solid expertise in modern front‑end technologies, including Angular, Bootstrap (versions 4 and 5), CSS, SCSS, JavaScript, and JQuery.
