Data Scientist - Ads Marketplace

San Francisco, CA

Who We Are:

The ads marketplace team is responsible for placing each and every ad that Twitter serves. While placing those ads we decide how best to balance user experience, advertiser results, and Twitter revenue. Our team optimizes the ad delivery engine, manages demand/supply, and improves product outcomes by applying data science and machine learning skills. We routinely deliver significant improvements to our revenue, and work in a close sync with our executive staff (including our COO & CFO) due to our direct impact on Twitter’s business.

 

What You’ll Do:

We’re looking for a key individual contributor to drive our advertising products forward. Ads marketplace decides which ads to serve billions of times a day under a sub-second setting. You will ship new features and optimize existing products. You will perform rigorous analysis, understand our advertising products, experiment, make data-driven decisions, optimize for impact, and measure performance funnels.

Your team will empower you with the autonomy to make good product decisions and ship well-designed code. You’ll own significant projects end-to-end. The small teams of talented, passionate people in which you’ll work will include engineers and data scientists from across the revenue engineering organization. The ads marketplace team works on every high-priority ads project at Twitter.

 

Who You Are:

You’re a data scientist with a track record of delivering results. You find satisfaction in shipping changes that deliver measurable impact in the form of immediate revenue. You apply machine learning and data science techniques when applicable, but are just as happy to implement a simple heuristic when you find it’s as effective at driving impact to your product. You’re looking to join a strong, high-performing team.

  • We build more intelligent delivery algorithms resulting in better ROI for our advertisers

  • We are responsible for measuring the results of all experiments on Twitter ads
