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 data and software capabilities that turn advertising interactions and outcomes into reliable measurements, attribution, and insights.

As a Software Development Engineer III, you will help design and evolve the backend services and distributed data platforms that power advertising measurement, attribution, and reporting. You’ll work across data ingestion and processing, measurement services, and the delivery of dependable metrics to advertiser-facing and internal experiences. Your work will help advertisers and Expedia Group teams understand campaign performance and make informed decisions.

This role calls for strong technical ownership: you’ll shape solutions, deliver complex work across team boundaries, and help ensure that critical systems are scalable, observable, and dependable in production. You’ll partner with engineering, product, and analytics colleagues, and help raise the technical bar through thoughtful design, high-quality implementation, and mentorship.

In this role, you will:

Design, build, and operate scalable backend services and data-processing systems for advertising measurement, attribution, and reporting.
Lead technical implementation of complex features and contribute to architecture, API, and data-model design.
Build and evolve data pipelines that transform advertising interactions and conversion signals into accurate, timely, and trustworthy metrics and insights.
Improve reliability, scalability, latency, and data quality across mission-critical services and pipelines.
Apply strong software engineering fundamentals and advocate for maintainable code, automated testing, and effective CI/CD practices.
Establish and improve observability, operational readiness, and automation; participate in production support, incident resolution, and root-cause analysis.
Use service and product metrics to evaluate performance, identify opportunities, and measure the impact of engineering improvements.
Collaborate with product, analytics, and engineering teams to align technical solutions with advertiser and business needs, coordinating dependencies across teams.
Explore and apply emerging technologies, including generative AI, where they can meaningfully improve measurement workflows, platform capabilities, or engineering productivity.
Mentor engineers and share practices that strengthen technical quality and team effectiveness.
