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?
Flex is looking for a Staff AI Engineer to join our AI Central Team and help us transform the way we work by building the tools and capabilities that support AI-first workflows across Flex.
As a Staff AI Engineer at Flex, you’ll help set technical direction and shape the long-term architecture of the AI systems and tools that all departments use to power their agentic workflows. You will own AI platform features and capabilities end-to-end including analysis, planning, implementation and production rollout to our internal customers. You’ll work closely with your AI Central Team peers and consult with department leads to anticipate business needs and proactively build the AI capabilities to address them. You’ll also play a critical role in mentoring, elevating technical standards, and ensuring the success of our Flex’s transformation into an AI-first organization.

Flex is a simple app that’s changing the way the world pays and collects rent. Our technology makes the 1st of the month easy for renters and properties.
For renters, we pay the rent on the 1st and let you pay it back when it works better for your budget. We help you buy some time (or whatever else you’re eyeing).
For properties, we help you collect more and stress less. And we do the previously impossible by turning rent collection into a marketable amenity.
WHAT WE STAND FOR
•We believe you should be able to choose when you pay your bills. The flexibility of buy-now-pay-later has forever changed the way the world makes purchases. We believe the same flexibility should be available for one of life’s #1 expenses: rent.
•We believe in the win-win. We like helping people keep commitments. With our technology, properties get the rent and renters get the time. The future is flexible.
•We believe in the end of rent regret. Sharing human spaces used to be easier. But then payment came into the picture and rent regret was born. The worst part of rent regret is that it separates us from each other. We’re committed to solving rent regret forever.
