Define and Measure Search Quality at Scale

- Own the development and ongoing measurement of customer experience metrics as reported to senior leadership

- Partner with leaders across Search, Retail, and Advertising organizations to align on metric definitions and establish independent measurement standards where needed

- Build scalable measurement frameworks that anticipate evolving search presentation formats and proactively adapt to them

Invest in State-of-the-Art AI Infrastructure

- Drive investment in AI infrastructure and systems that reduce the cost of measuring and monitoring CX metrics across all placements and marketplaces

- Build increasingly precise AI models that minimize human effort for auditing, training data generation, and placement-specific customization

- Make strategic build-vs-reuse decisions by staying closely connected to peer teams across the organization

Invent New Product Experiences

- Create novel product presentation experiences that help shoppers understand the differential value of each result - through intelligent selection of images and titles, contextual explanations, and visual indicators such as badges and tags

- Partner with peer teams to share learnings and advocate for the adoption of successful innovations beyond your immediate scope

Lead and Influence Across the Organization

- Manage and grow a team of applied scientists, engineers, and product managers

- Partner with senior leaders (Director-level and above) across multiple organizations to drive alignment on shared goals and cross-functional initiatives
