Polymarket is looking for a Senior Data Scientist / Analyst, Growth to own full-funnel GTM analytics across the business. You'll be accountable for understanding how users find us, what turns them into traders, and what brings them back.

This is a role for someone who wants to own a number rather than staff a request queue. You'll set the analytical agenda for your vertical: deciding what's worth measuring, telling marketing where the next dollar should go, and making the case when the data says the current plan is wrong. And you'll do it in a fast-moving environment where new markets launch constantly and the growth playbook changes with them.

  Own full-funnel analytics for your vertical, from paid acquisition through first trade to repeat engagement, and be the person who can explain what is driving each step

• →

  Partner with marketing on spend efficiency including CAC, ROAS, payback period, and channel mix, and make the call on where incremental dollars should go

• →

  Size and prioritize growth opportunities within your vertical: which leagues, events, or market types deserve investment, and what the return is likely to look like

  Write end-to-end documentation that’s clear and thorough enough that anyone on the team can pick up your analysis without friction

• Expert SQL. You can go from raw event tables to a defensible answer without help

• Deep fluency in full-funnel GTM metrics including CAC, ROAS, payback, conversion rate, retention, LTV, and the judgment to know when each one is misleading

• Experience embedded with marketing and product teams as a partner in the work, not a downstream request queue

• Comfort with ambiguity. You can scope a vague question into a real analysis and defend the assumptions you made along the way

• Strong communication. You can take a complex analysis to a non-technical audience and land the recommendation

• Comfortable operating in a fast-moving environment where business logic changes frequently and you need to keep pace
