Drive causal-inference-led decisions across Lyft's rider Partnership, Loyalty & Pay programs

This Staff-level role owns the data science roadmap for Lyft's Partnership, Loyalty & Pay (PLP) team, applying causal inference and experimentation to zero-to-one programs, incrementality measurement, and executive-facing strategy. Expect deep technical questioning on causal methods (A/B testing, diff-in-diff, synthetic control, quasi-experimental design) alongside scrutiny of your ability to set team priorities, present to VP/C-level stakeholders, and mentor other scientists. Strong answers combine methodological rigor with business judgment and clear executive communication.
