  • Deep technical expertise designing and operating cloud-native applications on AWS, including service-to-service communication patterns such as gRPC, and working with datastores and caches such as Redis/Valkey, Cassandra, MySQL, and PostgreSQL.

  • Guide the safe integration and operation of AI/ML-enabled capabilities in the content domain, including establishing technical guardrails, evaluation approaches, and operational practices for production use.

Desired Qualifications

  • Proven experience defining and evolving architecture for content platforms spanning multiple services or domains, including clear API contracts, domain models, and data strategies that enable reuse, scalability, and future extensibility.
  • Provide technical leadership for content platforms and services, setting architectural direction for backend systems that power scalable content acquisition, enrichment, curation, and delivery across Expedia Group.
  • Provide technical guidance for full-stack, operator-facing, and partner-facing capabilities where needed, including internal tools, user interfaces, and user experiences that support content workflows, platform operations, developer efficiency, and external partner use cases.
  • Strong focus on engineering excellence and operational rigor, including driving standards for automated testing, continuous integration and continuous delivery pipelines, production readiness, and reducing operational toil across teams.
  • Ability to use data, experimentation, and metrics to set technical direction, validate architectural decisions, and iteratively improve content features, workflows, and platform capabilities at scale.
  • Experience leading or guiding teams in implementing or extending AI/ML-enabled content capabilities such as classification, ranking, generation support, or quality evaluation, with a focus on safe integration, technical guardrails, and responsible usage aligned to Expedia Group standards.

About the Company

Expedia Group

Runs travel booking sites for people and companies

Expedia Group runs online travel brands such as Expedia, Hotels.com, and Vrbo, where people book hotels, vacation homes, flights, and rental cars, and it supplies the same travel to other companies. Its Expedia site was one of the first online travel agencies, letting people compare and book flights and hotels on the web without calling a travel agent. Travelers search and pay through its apps and websites, while partners such as airlines and banks plug its hotel and flight listings into their own booking sites. Expedia earns commissions and markups on bookings and sells advertising to hotels and other travel companies. It began in 1996 as a division of Microsoft and is based in Seattle, Washington.
