Lead Product Manager, Partner Integrations (New Verticals)

Flex is a growth-stage, NYC headquartered FinTech company that is creating the best rent payment experience. It’s hard to believe that it’s 2026 and paying rent on time is expensive, inflexible, and difficult. We’re here to change that! Flex enables our users to pay rent throughout the month on a schedule that better fits their finances and budget. Our mission is to empower as many renters as possible with flexibility over their most significant recurring expense. After deliberately keeping a stealth profile as we built up unprecedented investor support and an enthusiastic user base, we are looking for motivated individuals to help us keep our mission growing. Will you be a part of the team? Why Flex needs YOU Flex has built a large, rapidly growing business that helps consumers pay their largest bills on time — starting with rent. At the core of our product is a network of partner integrations that connect Flex to the billing systems and payment portals that consumers interact with every day. We are now expanding beyond Rent into new verticals such as insurance, utilities, auto, and more. We need a Product Manager who can help us move fast, figure things out, and “roll with the punches” as we evaluate different approaches to scaling the biller network. This role is for someone who thrives in the middle of the action, can hold a lot of context at once, and gets satisfaction from turning chaos into working product.
