About the project

Our client is a travel technology product company with HQ in Dubai and an engineering hub in Warsaw. It builds a cloud-native airline retailing platform that connects airlines for digital retailing and processes millions of ticket purchases every month.

The team is now moving the platform from the legacy Passenger Service System (PSS) model to the modern Offer/Order (OOSD) model. Part of this work is a bridge layer that maps PNRs, E-Tickets/EMDs, RBDs and fare basis codes to Orders, Offers, Products and inventory buckets. The move happens in phases: first one-way data priming (PSS → OOSD), then two-way synchronisation (PSS ⇄ OOSD).

The client builds and owns its product, so engineers shape architecture and technical decisions instead of just implementing tickets. The team is international, and English is the everyday working language.

Tech stack: Java, Spring Boot, microservices, REST APIs, AWS, MySQL, DynamoDB, EDIFACT and TTY messaging, AI coding assistants (Claude).

About the role:

We’re looking for a Senior Software Engineer (Java) with deep expertise in the airline PSS domain. You’ll use your hands-on experience with reservations, ticketing, inventory, schedules, fares and distribution to connect traditional PSS capabilities with modern Offer/Order retailing.

The role combines hands-on engineering with complex airline-domain challenges. You’ll work closely with Product Managers, Architects and other engineers. AI coding assistants are part of the daily engineering workflow.

You have:

Software engineering

• 7+ years of professional experience with Java
• Strong experience with Spring Boot and microservices
• Solid experience building and integrating REST APIs
• Experience with AWS (preferred) or other cloud platforms
• Strong engineering fundamentals, clean code and automated testing
• Experience with relational databases, particularly MySQL
• Strong analytical and problem-solving skills
• Fluent English, both written and spoken

Airline PSS domain

• Extensive hands-on experience building digital solutions in the airline PSS domain
• Reservations: PNRs and End-of-Transaction (EoT) processing
• Ticketing: E-Tickets and EMDs
• Schedules: SSIM, ASM and ASS setup, maintenance and distribution
• Inventory: RBD setup, maintenance and distribution
• Fares & Pricing: fare filing and ATPCO
• Distribution: EDIFACT and TTY messaging

Would be a plus:

• NoSQL databases, such as DynamoDB
• IATA standards, PADIS messaging, PNRGOV and related airline data formats
• NDC and Offer/Order (ONE Order) retailing models
• Departure Control Systems (DCS): check-in, weight & balance, load control
• GDS connectivity (Amadeus, Sabre, Travelport), interline and codeshare integration
• Distributed and event-driven system design
• Airline-grade non-functional requirements: high availability with minimal or no maintenance windows, high-throughput transactional processing, low-latency shopping and availability
• Awareness of PCI-DSS and GDPR requirements for passenger data
• AWS certification
• Practical experience with AI-assisted software development

You are going to:

• Design, develop and evolve Java microservices on Spring Boot, plus REST APIs and cloud-native services
• Work on core PSS capabilities: reservations, ticketing, inventory, schedules, fares and distribution
• Build the bridge between legacy PSS and the Offer/Order (OOSD) platform, translating legacy concepts into clean OOSD-native designs
• Build and improve airline integrations over EDIFACT and TTY
• Design solutions for airline-grade requirements: high availability, scalability, performance and transactional integrity
• Work with Product Managers and Architects to turn complex domain requirements into robust technical solutions
• Improve existing services in terms of performance, reliability and maintainability
• Contribute to architecture discussions, technical decisions and engineering best practices
• Write clean, well-tested code, using AI-assisted tools as part of your daily workflow
