Key job responsibilities

The Principal Applied Scientist will drive transformative innovation in Sponsored Products and Brands (SPB) auction design across non-search surfaces, including product detail pages, the home page, and specialty stores. This role will be pivotal in rethinking how ads contribute to a personalized, relevant, and inspirational shopping experience, with the customer value proposition at the forefront. The key responsibilities include but are not limited to:

Auction Mechanics and Optimization: The Principal Scientist will reimagine auction mechanisms to holistically consider business drivers and shopper needs. This involves developing new auction functions that considers ad relevance, order product sales, ads revenue, cost-to-serve, and advertiser demand, while remaining sensitive to seasonality, holidays, and bespoke shopping experiences (e.g., premium or grocery shopping). The scientist will entail the design and testing of auction models and simulations to improve multiple objectives. Specifically, they will estimate how different auction parameters perform under varying shopper cohorts (e.g., first-time versus repeat shoppers), product categories, seller types (e.g., vendors versus sellers), and regional demand profiles, setting the foundation for adaptive auction strategies that maximize value for both shoppers and advertisers.

Ad Inventory Management from a Customer-Centric Perspective: The Principal Scientist will lead initiatives to redefine how we manage ad inventory allocation across non-search pages, focusing on how the amount of ads shown and how ads content blend with organic recommendation align with the intent and needs of shoppers in various contexts. Leveraging large-scale machine learning (ML) and large language models (LLMs), the scientist will design, prototype, and iterate models that predict, measure, and improve the efficiency and effectiveness of ad inventory allocation that consistently delivers a clear customer value proposition.

Advancing Scientific and Technical Capabilities: As a senior leader, the Principal Scientist will play a critical role in elevating the team’s scientific and technical rigor, identifying and implementing best-in-class algorithms, methodologies, and infrastructure that enable rapid experimentation and scaling. They will establish a long-term vision for continued scientific innovation, setting strategic goals to future-proof the organization’s technical stacks and ML/LLM frameworks to support new and emerging business objectives. Additionally, the scientist will mentor and guide junior scientists and engineers, fostering a culture of excellence and continuous learning to enhance the organization’s ability to solve complex problems in advertising science.

Through his/her work, the Principal Applied Scientist will directly impact key business metrics by improving ad relevance and auction efficiency, ultimately contributing to revenue growth, improved customer satisfaction, and differentiated shopper experiences.
