Price is a key factor influencing travellers’ path to driving a choice leading to a purchase. In a world of infinite paths to purchase, travellers make multiple searches and find the ‘best trip’ and ‘best deal’. The Offers Domain team is tasked with providing the customer with simple, clear, accurate, and transparent pricing throughout their shopping and booking journeys. We do this by putting the customer first, creating capabilities that can be shared with and presented to the customer, meeting travellers’ expectations in locally relevant ways and adhering to regulatory norms.

• Experience using modern AI-assisted development tools (for example, IDE assistants, chat-based coding agents, or AI-augmented code review/testing tools) as part of your daily workflow, beyond simple code autocompletion, and are comfortable working in an AI-integrated environment.

Preferred Qualifications:
