Job Description

Flex is building a finance super app for premium business owners — reimagining every single aspect of the financial workflow and financial services for any entrepreneur. The company has grown revenue 25x+ since publicly launching in September 2023 and is on track to achieve profitability by late 2025. Flex is focused on mid-market businesses ($3 - $100M revenue) that are largely overlooked by existing fintech solutions and reliant on slow and outdated regional banks.  We are targeting a ~$1T revenue opportunity that is largely up for grabs.

Flex is a fully remote company and this role can be performed from anywhere.

The Director of Underwriting at Flex is a dynamic owner / operator role, where you will not only lead the underwriting team but also directly engage in underwriting activities. This position requires you to assess the creditworthiness of businesses using customer-supplied financial documents and third-party data, ensuring decisions align with Flex’s strategic objectives. You will also be active in reviewing and enhancing the work of other underwriters, providing guidance to foster their professional growth and improve overall team performance in terms of decision quality as well as process efficiency. Reports to the Chief Risk Officer.

Key Responsibilities

• Directly underwrite applications to assess business creditworthiness, employing both customer financial documents and third-party data such as commercial credit bureau reports.
• Actively review and validate underwriting decisions made by team members, supplying constructive feedback and coaching to enhance their skills and decision-making capabilities.
• Employ sophisticated methodologies to identify credit risks and prevent fraud, mitigating potential challenges within the underwriting process.
• Develop and refine underwriting policies that align with Flex’s strategic goals and maintain low default probabilities.
• Mentor and lead the underwriting team, fostering an environment of continuous learning, innovation, and accountability.
• Collaborate with cross-functional teams to streamline underwriting processes and contribute to achieving Flex’s business objectives.
• Collaborate with other parts of the Risk org (Portfolio Management, Analytics, Strategy development) to create an efficient lifecycle view of the Credit Portfolio that leads to maximization of customer lifetime value within and across products.
