Our Team

The Ad Supply & Decisioning team within the Ads Data Science and Engineering (DSE) organization drives ads growth by expanding ad inventory, optimizing member-ad matching, and maximizing long-term yield. The team spans three pillars, Ad Forecasting, Ad Ranking, and Ad Marketplace, and supports all ad surfaces, including live events such as sports, award shows, and cultural moments watched simultaneously by tens of millions of members around the world. Live advertising introduces a distinct class of problems: massive, unpredictable traffic spikes, global simultaneous delivery, hard real-time latency constraints, and the need to balance yield across direct and programmatic demand channels.

We are looking for a Machine Learning Scientist 6 to serve as a vertical technical lead across our core Live Ads ML problem areas - forecasting, targeting and personalization, bidding and pacing, auction, and yield optimization.

• Build, train, and evaluate models on large-scale production data.

• Develop online and offline evaluation frameworks to rigorously measure the impact of model and algorithm improvements.

• Partner closely with the product team to define optimization objectives, constraints, and trade-offs that align with product and business goals.

• Communicate technical decisions, trade-offs, and experiment results to both technical and non-technical stakeholders, including senior leadership.

Qualifications

• Advanced degree (PhD or Master's) in Computer Science, Statistics, Mathematics, or a related quantitative field.

• 7+ years of industry experience building and shipping production ML systems at scale, with demonstrated staff/senior staff-level scope and impact.

• Deep knowledge of machine learning, optimization, and data analysis techniques.

• Experience in ad optimization stack, e.g. targeting, ranking, bidding. Experience in Live ads is a huge plus.

• Proven ability to set technical direction and influence roadmap across teams; experience serving as a vertical or staff-level technical lead is a strong plus.

• Experience with prototyping and deploying algorithms using large-scale production data.

• Proficiency in Python, Scala, or Java.

• Strong business acumen and ability to translate technical results into business impact.

• Excellent communication and collaboration skills.
