Polymarket is looking for a Senior Data Scientist / Analyst to be the analytical partner to our product team and the person who can say whether what we shipped actually worked. 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
Partner with product managers, designers, and engineers as the analytical owner for product
Define the metrics that determine whether a feature worked, and be the person willing to say plainly when it did not
Design, instrument, and read A/B tests end-to-end, including the calls on sample size, guardrail metrics, and when to stop a test
Build the funnel and behavioral analyses that explain how users find a market, place a first trade, and come back for the next one
Turn user behavior into product direction. Surface where people drop off, what the friction actually is, and what is worth building next
Own the event tracking spec for your area, working with engineers so instrumentation lands correctly the first time rather than being reconstructed later
Work with analytics engineers to promote your recurring analyses into modeled datasets rather than one-off queries
Write end-to-end documentation that’s clear and thorough enough that anyone on the team can pick up your analysis without friction
