What the job involves

- Own the data science strategy and roadmap for ranking and relevance as the team's dedicated data scientist

- Partner closely with engineers to improve ranking models end to end, from defining what the model should optimize through experimentation

- Own experiment design and turn results into clear launch recommendations

- Design measurement that holds up in a marketplace, where bias and interference between advertisers can distort results

- Apply rigorous observational methods when experiments aren't possible, and defend the assumptions behind them

- Build marketplace frameworks that balance advertiser, user, and platform value with clear success criteria and guardrails for the trade-offs

- Separate true incremental gains from value that's simply shifted between advertisers, surfaces, or time periods

- Measure how changes impact different user and advertiser segments, distinguishing durable value from short-term lift

- Use findings to shape targeting and investment strategy, accounting for uncertainty

- Quantify commercial impact to guide senior leaders on priorities and product decisions

- Serve as the core data science partner to commercial and offer teams, turning business goals into measurable objectives and ranking improvements





- Communicate with technical and non-technical partners alike

- Mentor others and build reusable methods that raise the team's scientific quality and execution
