Commercial Software Engineer Level 3

Digital IT and Business aim to make the digital channel each traveler’s favorite by providing spot-on offers and services at every step of the journey; the Offer and Order components are at the heart of this and are essential for our customers to buy their tickets and ancillary products and manage their (re)-bookings. As a Commercial Software Engineer, you play a crucial role in achieving this Digital ambition.

The airline ticketing domain is complex. Tickets are sold 24/7 worldwide. The Order domain is mission critical and consists of numerous separate systems to manage inventory, control pricing, support different booking flows, process payments etc. Performance and security are key aspects of the software development. There is a lot of attention for innovation in the Order domain, on the technical and functional side. Migration to the Azure Cloud has been finalized and Cloud native options are explored, new airline industry programs like ‘One order’ are evolving.

Besides Java 21, also Kotlin, Groovy and Scala are used. The existing Order modules offer regular REST and SOAP web services using Spring Boot. The teams are continuously improving their agile/scrum way of working and quality through code reviews, automated testing, and refactoring. Since there are many teams that depend on each other to deliver functionality, SAFe (Scaled Agile Framework) is used.
