Software Development Engineer III

About the role

Expedia Group's Reservations team owns the platform that processes and manages bookings across every Expedia point of sale globally. This is the system that turns a traveler's intent into a confirmed reservation and keeps that reservation accurate, accessible, and actionable throughout the trip lifecycle. The platform runs on a modern microservices architecture in AWS. It handles millions of booking transactions daily with high availability and low latency. We are in the middle of a significant architecture evolution, making the reservation platform more flexible for product servicing while maintaining the performance and reliability bar our travelers and partners depend on. This is infrastructure that matters. When it works well, travelers trust Expedia with their plans. When it doesn't, they feel it immediately. We are looking for a Senior Software Development Engineer who will own critical backend systems end to end. You will design, build, and operate services that handle real money, real travelers, and real-time constraints. You will make technical decisions that affect the reliability and extensibility of a platform serving hundreds of millions of users. You will not be handed a spec and asked to implement it. You will identify the right problems to solve, propose the architecture, drive alignment with stakeholders, make trade-offs explicit, and deliver. You will own the operational health of what you build. You will mentor engineers around you and raise the engineering bar for the team through code reviews, design reviews, and technical leadership in ambiguous situations. This role requires someone who thinks in systems, not features. Someone who asks "what breaks at 10x scale" before writing the first line. Someone who treats operational excellence as a first-class engineering concern, not an afterthought.
