Qualifications

Key ResponsibilitiesEnhance A/B Testing Efficiency: Spearhead the implementation of variance reduction techniques (CUPED) and sequential testing to boost platform sensitivity and speed. Develop strategies to minimize interference and network effects, ensuring outcomes reflect true causal impacts in a complex auction environment. Scale Ranking Evaluations: Design and implement interleaving frameworks to quickly evaluate ranking model performance in real-time, enabling identification of superior candidates significantly faster than conventional bucket testing. Mitigate Budget Cannibalization: Create methodologies to manage finite advertiser budgets and prevent experimental groups from interfering with each other's expenditures. Develop pacing-aware evaluation techniques to uphold marketplace integrity and ensure unbiased results. Establish LTV Proxy Metrics: Research and validate surrogate metrics that strongly correlate with long-term user retention and value, providing machine learning teams with short-term signals that accurately predict long-term impacts for quicker optimization. Automate ML Experimentation: Build the statistical foundations for automated pipelines that autonomously test and select optimal features and hyperparameters, reducing manual engineering overhead and accelerating the deployment of high-performing models at scale. Cross-Functional Leadership: Act as the leading subject matter expert on experimentation for machine learning, product, and engineering teams, ensuring statistical rigor is integrated throughout the entire product lifecycle.
