About the role

• Identify growth opportunities: analyze user behavior, funnel drop-offs, and cohort retention to uncover high-leverage opportunities.
• Design and run experiments: prioritize, ship, and iterate on experiments across onboarding, referrals, lifecycle flows, pricing, and in-product nudges.
