Director, Applied Science - Ad Optimization & ML Systems
Full Job Posting
MUST HAVE
- 10+ years of experience building and deploying production machine learning systems, with at least 5+ years in a hands-on technical leadership role
- Direct experience with real-time, high-scale decisioning systems — ad optimization, bidding, ranking, recommendation, or a closely comparable domain with similar latency and volume constraints
- Demonstrated ability to formulate an ambiguous business problem into a precise ML specification: labels, training population, objective, loss function, and evaluation metrics — without relying on framework-level generalities
- Working fluency in the operational demands of production ML: delayed feedback, latency and serving tradeoffs, monitoring, drift, and retraining
- A track record of technical leadership: reviewing and improving other scientists' system designs, not just managing their output
- Bachelor's degree in Computer Science, Engineering, or a related field; Master's preferred
- GREAT TO HAVE
- Direct experience with real-time bidding, ad auctions, or programmatic advertising systems specifically
- Experience with identity resolution or cross-device/cross-platform user matching
- Experience with agentic or multi-step autonomous decisioning systems
- PhD in Machine Learning, Computer Science, or a related field
- Publications or conference contributions in ML or a closely related field
- Formal people-management tenure beyond the 5-year hands-on leadership requirement above
