Director, Account Management

Flex is a growth-stage, NYC headquartered FinTech company that is building the payment layer for life's essential bills, giving households one place to see, split, and pay their bills around how they live and get paid. By offering greater choice over how and when payments are made and allowing eligible on time payments to help build a positive credit history, Flex puts households back in control of their cash flow.

That work brings together people with different perspectives who challenge the status quo and take ownership of solving difficult problems. For you, that means doing the best work of your career next to people who make you better, and together bringing ideas to life that make a real impact for the people we serve.

About the role

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, with a clear mandate to drive 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 allow Account Management to scale, ensure partners are deeply engaged with Flex’s products, and translate partner relationships into durable, compounding business value.

You will also serve as a senior commercial leader internally, partnering with executives across the company and representing the voice of our partners at the leadership table. The ideal candidate is a seasoned, hands-on leader with strong commercial instincts, operational rigor, experience building and scaling teams, and a passion for building durable partner relationships in high-growth B2B or B2B2C environments.
