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
Flex is looking for a Staff Software Engineer to join our MarTech (Marketing Technology) team. This role involves spearheading the implementation of the platforms, services, and customer-facing web experiences that power how Flex finds, wins, and keeps customers.
MarTech is the connective layer between our ad platforms, website, messaging systems, analytics, and product data. We turn marketing spend into a measurable, repeatable growth engine, and give marketing the ability to launch, test, and personalize campaigns without hand-built engineering each time. It's a team with a broad surface area, owning growth engineering end to end across Lifecycle Marketing (email & SMS), Performance Marketing (paid acquisition), Brand (social and every getflex.com property), and Product Marketing.
Here are some of the projects and systems in MarTech you'll have opportunities to work on:
