Flex is an early-stage, remote-first FinTech startup that is creating the best rent payment experience. It’s hard to believe that it’s 2023 and paying rent on time is expensive, inflexible, and difficult. We’re here to change that! We enable 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 in 2023. Will you be a part of the team?

You’ll work closely with your product, design and engineering peers to solve our users' most pressing problems around rent payment. You’ll roll out changes to our customers in an agile manner with a delivery cadence that favors small, frequent iterations.  The ideal candidate will be comfortable leading scoping, design, prioritization, and implementation for APIs and services they build and can drive their production rollouts to completion with minimum oversight.
