Senior Software Engineer - MQE
About The Position
The Trade Desk is a global technology company and the world’s leading independent platform for digital advertising. Our technology helps advertisers reach the right audiences across the open internet. The Marketplace Quality Engineering team ensures our platform is buying the right impressions, not just more impressions. We own the systems that assess, measure, and optimize supply quality across the programmatic ecosystem. Our work spans deduplication, supply path analysis, quality modeling, and the tooling that turns those signals into decisions at bid time. The problems are technically deep and have direct, measurable impact on both advertiser outcomes and platform economics. Engineering decisions translate directly into tens of millions of dollars of measurable business impact. You will work with C# / .NET as a core strength, alongside Python and SQL where data and automation need it, and partner closely with product, data, and platform teams across time zones.
Requirements
- Comfortable working on an agile, distributed team across time zones and continents.
- Effective communication with both technical and non-technical audiences.
