Introduction to the Team

Expedia Group Advertising helps Expedia Group and its partners connect with travelers and understand the impact of advertising across Expedia Group brands and partner channels. Within Emerging Business Technology, the Measurement, Attribution & Data Platform organization builds the capabilities that turn advertising interactions and outcomes into reliable measurements, attribution, and insights.

As a Software Development Engineer II, you will contribute to the backend services and data platforms that support this work—from ingesting and processing advertising and conversion data to powering measurement and reporting experiences. The systems you build help advertisers and internal teams understand campaign performance and make informed decisions. You’ll work with engineers, product partners, and analytics stakeholders on distributed systems where data quality, timeliness, scale, and operational reliability matter.

We’re looking for an engineer who takes ownership, delivers thoughtfully, and cares about building maintainable systems that work reliably in production. You’ll have opportunities to contribute across the development lifecycle, improve existing platforms, and help evolve the way Expedia Group measures advertising outcomes.

In this role, you will:

Design, build, test, and operate scalable backend services and data-processing capabilities for advertising measurement, attribution, and reporting.
Develop maintainable software using sound design principles, data structures, and computer science fundamentals, with clear naming, modularity, and appropriate optimization.
Build and evolve data flows that transform advertising interactions and conversion signals into dependable metrics and insights.
Help ensure data quality, privacy, and appropriate handling of sensitive information across platform services and pipelines.
Improve system reliability, performance, and data timeliness through observability, automation, testing, and continuous operational improvements.
Participate in production support, troubleshooting, incident resolution, and root-cause analysis, with support from more senior engineers as needed.
Collaborate with engineering, product, analytics, and partner teams to deliver capabilities that support advertiser and business needs.
Contribute to technical design discussions and evaluate appropriate architectural patterns and emerging technologies, including GenAI where it provides clear value.

Minimum Qualifications:

Bachelor's degree or Master's in a related technical field, or equivalent related professional experience
2+ years of experience in backend software development, working with cloud-based and distributed systems at scale
Proficiency in Java or Kotlin, with hands-on experience integrating services with relational and NoSQL databases
Experience with CI/CD pipelines, infrastructure/test automation, and delivering features in Agile development environments

Preferred Qualifications:

Experience working on payment platforms or implementing backend services leveraging GenAI technologies
Experience contributing to multiple multi-quarter, cross-team projects
