Twitter is what’s happening and what people are talking about right now. For us, life's not about a job, it's about purpose. We believe real change starts with conversation. Here, your voice matters. Come as you are and together we'll do what's right.

We are a geographically-distributed team of Machine Learning Engineers that are responsible for placing each and every ad that Twitter serves. We focus on optimizing campaign performance and ROI for performance-minded advertisers, using modern ranking and personalization techniques. We prioritize impact, routinely deliver material improvements to the company’s ads revenue, and work across the entire ads ecosystem. Technically, we are involved in the full array of modern applied machine learning work, including ideation, experimentation, implementation, and maintenance. This includes work across our ads stack on predictive modeling, improving the way the system explores new traffic, mitigating effects of selection bias, effective budget pacing, efficient AB testing, accurate candidate ranking, visualizations, and more.
