You communicate effectively with executives and earn trust with senior engineers. • Bias to action. Comfortable making decisions with imperfect information, making reasonable risk/reward tradeoffs, and recovering fast when wrong. Nice to Have: • ML fluency. You've shipped ML-powered products in ads, content personalization, retrieval, ranking, or content understanding. You can reason about retrieval, candidate selection, ranking signals, and the tradeoffs between LLM-derived features and traditional features.
