Experience Required

Role Overview

Key Responsibilities

• Design, build, and maintain backend services in Core Java and Spring / Spring Boot for loyalty, customer-360, and reservation-adjacent workflows.
• Develop and maintain integration routes in Apache Camel — connecting upstream and downstream systems including loyalty engines, reservation platforms, and customer data stores.
• Design and expose REST APIs with clean contracts, proper versioning, error handling, and documentation (OpenAPI/Swagger).
• Translate functional requirements from business analysts into technical designs, and break them down into deliverable engineering tasks.
• Troubleshoot production issues across integration boundaries — including message-flow tracing, payload debugging, and root-cause analysis on Camel routes.
• Contribute to architecture and design discussions, especially where loyalty accrual/redemption, customer-profile resolution, and reservation events intersect.
• Write unit and integration tests; participate in code reviews; uphold engineering standards across the team.
• Work collaboratively with QA, BAs, and the broader programme team on UAT, defect resolution, and release cycles.

Required Skills & Experience

• 5+ years of hands-on backend development experience.
• Strong Core Java fundamentals — concurrency, collections, JVM behaviour, exception design.
• Airline Loyalty / Frequent Flyer Programme — accrual rules, redemption, tier qualification, partner earn/burn, member lifecycle. Hands-on engineering experience inside a loyalty platform (not just adjacent exposure).
• Customer-360 / Single Customer View — identity resolution, golden record, profile stitching across source systems, consent and preference data.
• Airline Reservation Systems — practical familiarity with PNR structures, passenger data, booking flows, and how reservation events propagate to downstream systems.
