You'll own product insights end-to-end, from defining its success metrics, to designing the experiments that test them, to telling the team what the results mean.This is a role for someone with real product instincts, not just query skills. You'll spend as much time forming hypotheses about why users behave the way they do as you will validating them, and you'll be expected to push back when a feature's numbers don't support the story being told about it. You'll do it all in a fast-moving environment where we ship constantly and the answer is usually needed before the next release.What You'll DoPartner with product managers, designers, and engineers as the analytical owner for productDefine the metrics that determine whether a feature worked, and be the person willing to say plainly when it did notDesign, instrument, and read A/B tests end-to-end, including the calls on sample size, guardrail metrics, and when to stop a testBuild the funnel and behavioral analyses that explain how users find a market, place a first trade, and come back for the next oneTurn user behavior into product direction.
