Flex is a growth-stage fintech company headquartered in NYC that is transforming rent payment by enabling renters to pay throughout the month on a flexible schedule that fits their finances. The company is now expanding into the mortgage vertical—one of the largest recurring expense categories in American life—and seeking a Senior Director to spearhead this zero-to-one expansion. In this role, you will report to the VP Strategic Partnerships (New Verticals) and own Flex's complete go-to-market strategy and pipeline for mortgage. You will identify and engage strategic partners across mortgage servicers, originators, servicing platform providers, and adjacent proptech players, building relationships and closing deals that establish Flex as the flexible payment solution for mortgage consumers. Key responsibilities include: - Building the mortgage vertical from the ground up by identifying, engaging, and closing enterprise partnerships across the mortgage ecosystem, establishing Flex's embedded split-pay offering as the standard for consumer payment flexibility. - Developing and managing a high-value, disciplined pipeline of strategic opportunities, moving prospects through the sales cycle with urgency and converting them into live, revenue-generating partnerships. - Serving as a credible, trusted advisor to C-level leaders and senior decision-makers, deeply understanding their strategic priorities and demonstrating how Flex creates value for their customers and business. - Owning complex deal negotiations end-to-end, structuring term sheets and partnership agreements that work economically and operationally for both parties. - Shepherding each partnership from signed agreement through technical deployment and go-live, working closely with Product and Engineering to ensure flawless execution. - Translating partner feedback and competitive dynamics into actionable input for Product, Marketing, and Pricing to sharpen positioning and offering. - Documenting learnings, establishing scalable processes, and developing the repeatable partner acquisition motion for efficient growth beyond initial market entry. You bring energy, push counterparts to think bigger, and find ways to win even when the path isn't clear. You know the mortgage ecosystem from the inside—who the buyers are, how they think, and what it takes to move a partnership from whiteboard to go-live. Requirements: - 10+ years of experience in enterprise sales, business development, or strategic partnerships, with meaningful experience selling into or partnering with mortgage servicers, originators, LOS/servicing technology platforms, or adjacent fintech and proptech players. - Track record of closing complex, first-of-kind deals in new markets, ideally involving embedded financial products, consumer payments, or BNPL programs in high-ACV, multi-stakeholder environments. - Deep knowledge of the auto ecosystem: understanding dynamics between OEMs, dealers, lenders, and consumers, and how payment flexibility fits into the purchase and ownership lifecycle. - Executive presence and influence: confident operation at the C-suite level, building trust with senior decision-makers and navigating complex organizations to drive deals to close. - Financial and legal acumen: ability to build and defend deal models, structure partnership economics, and negotiate agreements while balancing commercial rigor with pragmatic deal-making. - High agency and comfort with ambiguity: energized by building in undefined spaces, taking initiative without waiting for direction, and bringing clarity and momentum to evolving situations. - Cross-functional collaboration: successful alignment of Product, Engineering, and Marketing around partner priorities and leveraging those relationships to accelerate deal outcomes.
