Applied Scientist, Advertising, AMPI Measurement

Amazon is investing heavily in building a world-class advertising business and we are responsible for defining and delivering a collection of advertising tools and products that drive discovery and Advertiser success. Our products are strategically important to our Retail and Marketplace businesses driving long-term growth. We deliver billions of ad impressions and millions of clicks daily and are breaking fresh ground to create world-class products. We are highly motivated collaborative and fun-loving with an entrepreneurial spirit and bias for action.

The Marketing Effectiveness & Measurement Science team develops causal inference and machine learning systems to measure the impact of marketing programs across Amazons advertising ecosystem. We build production-grade measurement models and the calibration system that serves as the measurement truth layer continuously validating model outputs against RCTs and certifying them for high-stakes business and finance decisions. As our signals increasingly feed automated machine-speed consumers we are also transforming how we operate: building AI-assisted pipelines and agents that automate onboarding backfills diagnostics and reporting so scientists can focus on judgment and method. Our work sits at the intersection of econometrics scalable and reliable ML systems calibration and high-stakes business decisions.

As an Applied Scientist on this team you will own end-to-end modeling and production pipelines from problem formulation and experimental design through model development productionization calibration and stakeholder communication increasingly augmented by AI tooling and agents.

Major responsibilities include:

Translate / Interpret

Partner with cross-functional teams to translate business questions into rigorous causal inference problems
Design observational studies and quasi-experiments to measure marketing effectiveness when traditional A/B tests are infeasible
Work with data engineering to instrument new data pipelines when existing data cannot answer the causal question
Measure / Quantify / Expand

Own and evolve production attribution models across multiple marketing channels with the reliability latency and reproducibility that automated downstream consumers depend on
Build and maintain causal inference pipelines using methods such as Difference-in-Differences Synthetic Control Double Machine Learning and Media Mix Models
Develop and maintain calibration systems that benchmark model outputs against RCTs owning the measurement truth layer
Write scalable modular SDE-standard PySpark/Python codebases (CI/CD test isolation structured logging) that process large-scale event data and deploy to production with confidence
Continuously improve model accuracy through feature engineering heterogeneity analysis and sensitivity testing
Explore / Enlighten

Investigate anomalies in model outputs and deep-dive to identify root causes
Research and prototype next-generation measurement methods and apply AI/LLM-based tooling to accelerate the science development lifecycle

Make Decisions / Recommendations

Present findings to senior leadership with clear recommendations
Build dashboards agent-consumable APIs and self-service tools that let stakeholders (and downstream systems) explore results independently
Write production-quality Python for data analysis model training calibration and result publishing
