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

As a Staff Product Designer at Flex, you’ll solve problems for consumers across the country who are underserved by existing financial products. We’re handling people’s most significant recurring expense, which means the stakes of getting the experience right are real: a confusing screen or a poorly handled edge case can cost someone a late fee, a credit mark, or a difficult conversation with their leasing office.

We’re looking for a designer to own a product area end-to-end, developing a vision for where it’s heading, exploring the opportunities in front of it, and delivering the work that gets us there. You’ll define what good looks like for your part of the experience and hold that bar, from the first exploration through to what ships. All of your design skills will be put to use, from UX strategy to design thinking to interaction design and visual design.

This is a highly measured, highly cross-functional environment, with a big opportunity for designers to bridge true customer needs with creative solutions. You’ll work alongside product managers, engineers, data analysts, risk, and compliance partners, and most of what you design will run as an experiment before it becomes the default. The designers who do their best work here are highly creative with solutioning, curious about the numbers, comfortable with constraints, and willing to change their minds when the evidence says to.

What you’ll do

• Lead design for your team, contributing to the strategy and roadmap and owning all end-to-end design execution across your area
• Develop a vision and point of view for where your part of the experience is heading, and define the north star that informs and influences your team’s roadmap
• Own the design process from beginning to end: leading discovery, ideation, testing, visual design, and implementation
• Design for people under real financial pressure by bringing clarity, honesty, and dignity to flows where money and consequences are involved, including the error, pending, and recovery states that are easy to leave for last
• Proactively identify customer needs and partner with cross-functional leads to influence what your team prioritizes, rather than waiting for the work to arrive fully defined
• Partner with PM and analytics to structure experiments, informing hypothesis to test, understanding how you’ll measure success, and gathering meaningful learnings to bring into the next round of design decisions and your team roadmap
• Facilitate alignment with your cross-functional partners, stakeholders, and designers in other parts of the organization to ensure we are all designing toward a cohesive, considered customer experience
• Be steeped in your team’s customer and business goals.Do the research that informs the roadmap, and promote what you learn broadly so the rest of the company understands who we’re building for
• Care deeply for and lead by example by setting the standard for high quality craft through your approach to interaction design, prototyping, and visual design choices
• Build detailed prototypes, including micro-interactions and moments of delight, to dig into the details of how users will interact with the product
• Contribute to our Design System, Ultraviolet, including its foundational elements, aligning it with industry best practices and evolving our patterns to scale a modern, polished user experience
• Model how AI can raise both quality and velocity across the team through discovery, exploration, and prototyping. Plus if you’re comfortable shipping frontend changes with minimal support from engineering.

Key qualifications

• 8+ years experience designing and shipping consumer products
• Design ownership of a product or a family of features that had to work together in a complex space — not just individual features handed to you
• Fluency with experimentation. You’re comfortable designing for A/B tests, reading funnel and cohort data, and changing your mind when the result disagrees with you
• Strength in the unglamorous states (errors, edge cases, pending, and recovery)where a product either earns trust or loses it
• Comfort treating technical and regulatory constraints as design material rather than obstacles
• Track record of designing simple, intuitive products that are powered by complex systems and edge cases
• Comfort documenting and explaining your design process and rationale behind decisions, including leveraging best practices, research, and data
• Demonstrated aptitude for getting things done to make your team successful
• Strong native mobile app design experience (iOS and Android)
• Figma expert, and experience using AI tools to sketch and prototype
• Comfort with ambiguous problems and the motivation to be a self-starter
• Passion for improving every day people’s financial well being
• A portfolio of work detailing your contributions to shipped solutions

Nice to have

• Experience in fintech or another regulated environment, designing disclosures or money movement flows alongside legal and compliance partners
• Experience in an experimentation-heavy product organization where most changes ship behind a flag
• Enough familiarity with the frontend to make small changes yourself and to have a productive argument with an engineer about feasibility
