We build systems that detect and prevent fraud, measure and improve inventory quality, and optimize marketplace dynamics to deliver better outcomes for advertisers, publishers, and consumers.

• Define and maintain metrics, experimentation procedures, and monitoring systems to ensure long-term performance.

• Develop analytical and explainability frameworks that provide clear visibility into how quality initiatives impact inventory supply, advertiser spend, and marketplace dynamics.

Cross-Functional Impact 

• Collaborate with product and business stakeholders to translate analytical insights into clear, defensible decisions and marketplace enforcement strategies.

• Partner closely with engineering to deploy scalable, performant models.

• Anticipate emerging marketplace risks and proactively develop data-driven solutions to protect marketplace integrity.

Leadership & Mentorship 

• Act as a staff-level technical leader, setting standards for analytical rigor, model evaluation, and scientific best practices across MQE.

• Mentor and develop data scientists through design reviews, technical guidance, and career coaching.

• Influence technical direction across teams by driving alignment, knowledge sharing, and a culture of high-quality decision-making.

WHO WE ARE LOOKING FOR

• 7+ years of experience working in a DS role that involves bringing products from ideation to production.

• Deep expertise in statistical modeling, machine learning, and large-scale data analysis.

• Strong understanding of experimentation, causal inference, and metric design in complex systems.

• Familiarity with large-scale data and ML tooling (e.g. Spark, distributed training, real-time inference systems).

• Proven ability to lead ambiguous, high-impact projects end-to-end as a senior individual contributor.
