Staff Data Scientist – Ads Measurement, Signals, Privacy

About This Opportunity

We are representing a confidential social media technology company in their search for a Staff Data Scientist to lead critical work in advertising measurement, identity resolution, and privacy-safe signal optimization. This is a high-impact, high-autonomy role where you'll drive strategic direction and set the technical bar for how advertisers measure and optimize their campaigns on one of the internet's most engaged platforms.

Our client operates at massive scale, supporting tens of thousands of active communities and serving millions of daily users across Canada and globally. You'll be joining their Ads Data Science organization to solve some of the industry's hardest problems around measurement rigor, identity graph development, and signal maximization—all while respecting user privacy.

Responsibilities

• Design and implement probabilistic models for identity resolution that link on-platform and off-platform user actions while maintaining privacy standards
• Own the statistical methodology behind Brand and Conversion Lift measurement products, innovating experimental design and infrastructure for large-scale advertiser testing
• Define strategy for new signal sources, quantify their value mathematically, and collaborate with modeling teams to integrate them into predictive systems that improve bidding efficiency and return on ad spend
• Solve validation challenges by designing objective functions and truth sets used to train models and measure the incremental impact of identity graphs
• Lead cross-functional initiatives with engineering, product, and sales teams to translate insights into executable roadmaps
• Mentor data scientists and set best practices across modeling, experimentation, and measurement disciplines

What We're Looking For

Required Qualifications:

• Advanced degree (Master's or Ph.D.) in Statistics, Mathematics, Physics, Economics, or Operations Research
• 10+ years of industry experience for M.S. holders, or 6+ years for Ph.D. holders in applied science or data science roles
• Deep understanding of the digital advertising ecosystem
• Demonstrated expertise in at least one of: measurement and experimentation at scale (lift and attribution focus), identity graph creation and resolution methodology, or predictive modeling with signal loss considerations
• Advanced proficiency in statistical programming (Python or R) and SQL
• Experience applying machine learning or optimization techniques to real-world problems
• Strong foundation in experimental design, causal inference, and A/B testing methodologies
• Exceptional problem-solving and communication skills with a proven track record of influencing product and engineering stakeholders
• Comfort working in fast-paced, ambiguous environments with cross-functional teams
