About the role
We are seeking a Senior Java Full Stack Developer to support a major modernization initiative that will transition legacy disability and leave claims systems to a modern, cloud‑based platform.

· Develop and enhance Spring Boot microservices for core business logic and data management.
· Ensure all data access aligns with governed API and target architecture standards.
· Integrate services with internal systems (policy administration, claims, payments, treasury, identity services) and external portals.
· Collaborate with BPM teams using Appian for workflow orchestration and low/no‑code UI development.
· Work within legacy technologies, including:
§ JSP, HTML, JavaScript, CSS
§ Java on Tomcat
§ Sybase with extensive T‑SQL
§ UNIX batch processing (~800 ksh scripts)
§ SQR reporting
· Participate in modernization efforts while ensuring operational stability.
· Develop and deploy services using AWS technologies (Fargate, Lambda, S3, Aurora PostgreSQL).
· Containerize applications using Docker.
· Support CI/CD pipelines via GitLab.
· Work in hybrid runtime models (on‑prem Docker + AWS).
· Follow disciplined change management and integration governance.
· Write unit and integration tests using JUnit and Mockito.
· Support secure API design using OAuth‑based authentication.
· Engage in code reviews, architectural discussions, and cross‑team collaboration.
