Experience Required

5–8+ years of professional Java development experience
Minimum 3 years working with Spring Framework in production (both classic Spring MVC and

Spring Boot)

Experience maintaining legacy enterprise Java applications alongside modern microservices is a

strong plus

Core Responsibilities

Maintain and extend a Java 21 / Spring 6.2.x MVC / Hibernate 6.6.x order fulfillment backend for

visa, passport, and travel document services (not Spring Boot — manually configured, WARdeployed to Tomcat)

Design, build, and support Spring Boot microservices that integrate with other platform services
Work across two parallel data-access stacks in the platform: a legacy precompiled framework and a

modern JPA/Hibernate stack — both operating on shared database tables

Develop and maintain JSP/Servlet views alongside newer Spring MVC views, plus supporting

jQuery/JavaScript

Write and manage Flyway database migrations (MySQL/MariaDB) across multi-country/multidomain deployment configurations
Implement and troubleshoot audit trails (Javers),



authentication/SSO (SAML via OneLogin, JWT),

and authorization/IDOR protections across orders, payments, debtors, and documents

Support payment processor integrations with correct handling of PCI-sensitive data and financial

precision (BigDecimal)

Generate reports and PDFs via JasperReports and iTextPDF
Build, containerize, and deploy services using Docker, front them with Nginx, and operate them on

Linux servers

Maintain and extend Jenkins CI/CD pipelines (Groovy pipeline scripts) for build, test, and

deployment automation, including ad-hoc Flyway migration pipelines

Collaborate with QA/DevOps to troubleshoot production issues across the monolith and

microservices, including cross-service data consistency (orders, milestones, billing)
