Senior Product Designer, Design Systems

Flex is a growth-stage, NYC headquartered Fin Tech company that is creating the best rent payment experience. It’s hard to believe that it’s 2025 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?

As a Senior Product Designer at Flex, you’ll help shape the future of financial access for consumers underserved by traditional products, partnering closely with our platform team to drive the evolution and adoption of our new Ultraviolet design system, as we migrate from our legacy foundation. You will lead initiatives from discovery through delivery—defining the system’s long-term vision, identifying opportunities for improvement, and creating scalable solutions that enhance product quality and team efficiency.

Your work will ensure tight alignment between design and engineering by keeping our Figma libraries accurate, intuitive, and fully synced with Storybook components. Collaborating with product managers, engineers, data analysts, and a talented design team, you’ll play a critical role in building seamless, meaningful experiences that improve the financial lives of millions of Americans.

This is a hybrid position with on-site expectations in our New York Headquarters or San Francisco/ Bay Area Office, 2-3 days per week depending on location. For candidates outside of a required location, you may be eligible for our relocation assistance program.
