Software Development Engineer III

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. This is a great opportunity for you to play a pivotal role in shaping our technical domain to power all Expedia Group’s brands and product lines.
 

In this role, you will:

• Design and implement scalable, robust, and maintainable systems and services across multiple domains, with a focus on reliability and performance.

• Develop complex application logic, APIs, and data models aligned to business goals and best engineering practices.

• Collaborate with cross-functional teams to deliver high-quality, full-stack solutions that integrate seamlessly across platforms.

• Lead technical efforts in system architecture, code reviews, and establishing engineering standards.

• Safely integrate and operate AI/ML-enabled solutions that improve outcomes, ensuring responsible use of advanced technologies.

• Proactively identify, diagnose, and resolve production issues, continuously improving system health and operational excellence.

Minimum Qualifications:

• Bachelor’s degree in Computer Science or a related technical field; or equivalent related professional experience.

• Hands-on experience designing, building, and operating large-scale, distributed systems and services.

• Strong proficiency in system design, API design, and data modelling.

• 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:

• Experience with container technologies (such as Kubernetes) and CI/CD tools or processes.

• Expertise in architecting end-to-end solutions integrating multiple systems or domains.

• Strong focus on operational excellence, including monitoring, automation, and incident response.

• Data-driven approach to problem solving and technical decision making, including leveraging AI/ML insights where appropriate.

• Deep knowledge of safely integrating AI/ML features into production systems and optimising their impact at scale.
