## About the role

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.

## What they're looking for

- Partner Integrations - Partner integrations work to standardize APIs, tools, and processes that let external partners connect to Flex for data sharing and payments across entry points like Flex Anywhere and Quick-Pay
- Fin Platform - Fin Platform is the monitoring and operations layer for Flex's billing and payment systems, covering dashboards, SLIs/SLOs, runbooks, deployment and on-call procedures to ensure reliability and readiness
- Money Team - builds and owns the platforms, tooling, and documentation powering Flex's payments, wallet, and settlement finance systems
- A Doer — you get things done efficiently, and you're comfortable rolling up your sleeves when something's blocking the team
- An Owner — you take full accountability for what you build, from design through production, and you always have a plan B
- Someone Collaborative — you bring people together to pressure-test ideas rather than working in a silo
