The Customer Growth & Experience (CGX) team owns the full customer lifecycle — from the moment a customer lands on plaid.com to their journey across onboarding, activation, adoption, and long-term success. Within CGX, this role sits at the intersection of Growth and GTM. We own the product experience for sales-worked customers across every segment — onboarding, premium features, upsell and cross-sell, and offboarding — and the internal tooling that makes Plaid's own sales organization faster and more effective at every stage of a deal. We're focused on growing and retaining the accounts sales brings in, and on using AI to meaningfully change how sellers and their accounts get served, not just to speed up existing steps. As a Product Manager on Sales-Assisted Growth, you'll own the experience for customers who come to Plaid through our sales team — SDRs, AEs, AMs from onboarding through expansion and offboarding: how they get set up, which premium features they unlock, how they discover and adopt new products, and how they're communicated with along the way. You'll also own the internal tooling that removes manual work for sellers and gives them the right view of their accounts
