JOB PURPOSE

Cinergie Digital is seeking an experienced Senior Software Engineer to be deployed with our airline client, a major international airline headquartered in Dubai with multibillion-dollar turnover, as part of their technology delivery team. This role is central to the design, development, and integration of enterprise-scale software systems — with particular focus on Java-based backend services, Spring Boot microservices, and Apache Camel-driven integration pipelines. The successful candidate will contribute to mission-critical platforms spanning loyalty, customer data, and reservation systems, working within an agile delivery environment alongside cross-functional airline IT teams.  

KEY RESPONSIBILITIES

Backend Engineering: Design and develop robust, high-performance Java applications using Spring and Spring Boot frameworks, following enterprise architecture standards.  

Integration Development: Build, maintain, and optimise integration flows using Apache Camel and RESTful APIs — connecting internal systems and third-party airline platforms.  

Loyalty & Customer Systems: Contribute to development and enhancement of Airline Loyalty Programme and Customer-360 platforms, ensuring accuracy of member data, tier logic, and reward processing.

Airline Reservation Integration: Support integration and functional development within Airline Reservation systems, applying domain knowledge to translate business rules into reliable software.  

Code Quality & Standards: Participate in code reviews, enforce coding standards, write unit and integration tests, and ensure software quality across the delivery lifecycle.  

Cross-Team Collaboration: Work closely with business analysts, QA engineers, and architects to deliver features end-to-end — from requirement to production deployment.  

Documentation: Produce and maintain technical documentation for APIs, integration schemas, and system design decisions.

Experience

5–8 years of hands-on software engineering experience with Java-based enterprise applications and integration frameworks.

Core Programming

Proficiency in Core Java and Spring Framework (Spring Boot, Spring MVC, Spring Data, Spring Security). Strong understanding of OOP principles, design patterns, and clean code practices.

Integration Skills

Hands-on experience with Apache Camel for enterprise integration patterns (EIP) and RESTful API design, development, and consumption. Familiarity with JSON/XML data formats and API security (OAuth2/JWT).

Domain Knowledge

Good-to-have: Prior exposure to Airline Loyalty Programme systems, Customer-360 platforms, and/or Airline Reservation systems is a strong advantage. Candidates with this background will be prioritised.
