Senior Software Engineer - Identity Team

The Trade Desk The Trade Desk · Media · Bellevue, WA · Software Engineering

Senior Software Engineer role focused on designing, building, and operating large-scale distributed systems and data products for identity graphs in the digital advertising domain. The role involves processing petabyte-scale data and constructing identity graphs in a privacy-conscious way, sitting at the intersection of data engineering, distributed systems, and data science/ML.

What you'd actually do

  1. Design, build, and operate large-scale distributed systems and data products that process petabyte-scale data across cloud and physical infrastructure.
  2. Collaborate closely with data scientists, platform engineers, and product teams to deliver reliable, high-performance systems that serve clients at global scale.
  3. Construct and maintain large-scale identity graphs — linking signals across devices, channels, and environments in a privacy-conscious way.
  4. Develop frameworks to continuously evaluate identity graph performance, measuring accuracy, coverage, and quality so our systems improve over time.
