Director, Account Management , NY; Salt Lake , UT

Flex is a growth-stage, NYC headquartered Fin Tech company that is creating the best rent payment experience. It’s 2026, and Flex enables users to pay rent on a schedule that fits their finances, with a mission to empower renters with flexibility over their recurring expense.

As the Director, Account Management, you will own the strategy, performance, and scaling of Flex’s Account Management function, leading a team of Account Managers while directly stewarding the company’s largest and most strategic partnerships. This role sits at the intersection of partner success and revenue growth, driving retention, expansion, and long-term value across a growing book of business that represents a material portion of company revenue.

Reporting to the Vice President of Account Management, you will set the vision and operating model for the function — not just executing account strategy, but defining it. You will build the playbooks, processes, and team structure that enable Account Management to scale, ensure partners are deeply engaged with Flex’s products, and translate partner relationships into durable, compounding business value. The ideal candidate is a seasoned, hands-on leader with strong commercial instincts, operational rigor, experience building and scaling teams, and a passion for durable partner relationships in high-growth B2B or B2B2C environments.
