Job description

The Trade Desk is a global technology company and the world’s leading independent platform for digital advertising, with nearly 4,000 employees across more than 30 offices. Our technology helps advertisers reach the right audiences across the open internet — from streaming TV and podcasts to mobile apps, news, and more.

Advertising powers the content people love. By making it more transparent, effective, and responsible, we help support trusted journalism, quality entertainment, and creators worldwide. The world’s brands and agencies rely on us to reach their customers and grow their businesses responsibly.

The scale of our platform brings unique technical challenges — from processing massive datasets in real time to building systems that operate reliably on a global scale. When you work here, your impact is worldwide. We welcome diverse perspectives, encourage curiosity, and build teams that learn from one another.

You will develop advanced machine learning or deep learning models that directly influence planning, allocation and performance on our platform.

The main job directions include:

Develop forecasting models using statistical, ML and deep learning approaches.
Build and optimize pacing algorithms that balance short-term performance with long-term objectives and constraints.
Build custom solutions tailored to our unique environment, where off-the-shelf models often don’t scale effectively.
Collaborate with product teams to understand business goals and translate them into actionable data science solution.
Work closely with engineering teams to deploy models from prototype to production, ensuring smooth integration into products.
Define success metrics, conduct offline evaluation and online experiments (A/B testing), and measure business impact.
Communicate technical results and tradeoffs clearly to technical and non-technical audiences.
