Director of Product, Martech & Growth Platform

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?

About the Role

We are seeking a Director of Product to lead the Martech and Growth platform at Flex - a 0→1 build role at the intersection of data engineering, marketing intelligence, and consumer growth.

You will be the first to own this function at Flex, sitting in Product and serving marketing leadership as your primary internal customer. You will build and own the infrastructure, data, and tooling that makes campaigns possible, measurable, and increasingly intelligent.

As we scale direct-to-consumer acquisition through paid social and expand into new biller verticals, you will build the data and intelligence infrastructure that makes that growth compounding rather than linear- a unified identity spine, attribution architecture that moves beyond last-click, lifecycle infrastructure that personalizes at scale, and an ML intelligence layer that gets smarter over time.

You will be accountable for CAC efficiency outcomes, identity match rate and audience quality on paid platforms, and measurable lift from ML-driven lifecycle interventions - all built from greenfield. This is a role for someone energized by the scope of what isn't there yet.
