Job details:
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)
Required Technical Skills
Languages & Core
- Java 17/21 (strong OOP, collections, concurrency fundamentals)
- SQL (MySQL/MariaDB), schema design, query optimization
Frameworks
- Spring Framework 6.x (Core, MVC, Data JPA, TX, AOP) in a non-Boot, manually configured setup
- Spring Boot 3.x for microservices development (REST APIs, auto-configuration, embedded Tomcat)
- Hibernate/JPA 6.x (entity mapping, inheritance strategies, lazy loading pitfalls)
- JSP, JSTL, Servlets (legacy web tier)
Data & Migrations
- Flyway (versioned and repeatable migrations, multi-environment strategy)
Security & Integration
- SAML SSO (OneLogin or equivalent), JWT-based authentication
- REST API design; exposure to SOAP/WSDL a plus
- Awareness of OWASP Top 10, especially IDOR/access-control issues in multi-tenant order/billing
data
Reporting
- JasperReports and/or iTextPDF (report/PDF generation experience)
Frontend (supporting, not primary)
- jQuery / vanilla JavaScript
- Exposure to a modern frontend (React) is a plus, as some admin tooling is React-based
Build & Tooling
- Gradle (multi-project builds, custom tasks/plugins)
- Git
DevOps / Infrastructure
- Docker (building/running containers, multi-service compose setups)
- Nginx (reverse proxy/routing configuration)
- Linux (comfortable administering/debugging services on Linux servers)
- Jenkins (writing/maintaining Groovy pipeline scripts, CI/CD for build+deploy)
Nice to Have
- Prior experience in travel, visa/passport processing, fintech, or order-management domains
- Experience with audit/versioning libraries (e.g., Javers) or similar change-tracking systems
- Exposure to Joda-Time and date/timezone handling across multi-country deployments
- Familiarity with microservice patterns: service-to-service communication, eventual consistency,
distributed transactions across a monolith + microservices boundary
Soft Skills / Working Style
- Comfortable navigating and safely modifying a large legacy codebase without full documentation —
must exercise judgment on what's safe to change vs. what's tribal-knowledge-dependent
- Strong attention to financial and PII data handling given the sensitive nature of orders, payments,
and travel documents
- Ability to work across both monolith maintenance and new microservice development without forcing
one architectural style onto the othe
