About the Role

We’re looking for a Senior Director, Business Development (New Verticals) who lives for the hunt — a strategic seller who knows how to open doors, build conviction, and close complex platform deals that move the needle. You’ll take Flex’s pay-over-time platform into new industries and build the partnerships that define our next wave of growth.

This is a high-impact, outward-facing role where performance is measured in deals closed and markets won. Reporting to the VP of Strategic Partnerships, you’ll own the full sales motion — from pipeline creation and partner outreach to negotiation, launch, and revenue scale. You’ll target major payment platforms and vertical SaaS providers across insurance, utilities, telecom, auto, and healthcare, collaborating with GTM and Sales leadership to drive measurable adoption and sustained growth.

What You’ll Do

• Originate and Build New Partnerships. Proactively source, qualify, and pursue aggregator and platform partnership opportunities that unlock scalable access to new industries. Drive outbound prospecting, relationship development, and creative deal sourcing to build a healthy, high-value pipeline.
• Structure and Close Complex Deals. Lead the full lifecycle of strategic negotiations—including commercial terms, pricing, exclusivity, and go-to-market commitments—working cross-functionally with Legal and Finance to finalize agreements that drive material business impact.
• Develop Market Entry & GTM Strategies. Define Flex’s entry strategy for new payment categories, identifying where platform integration creates the most leverage. Translate market insights into actionable go-to-market plans and partnership roadmaps.
• Enable Scalable Distribution Through Platforms. Secure one-to-many integrations with partners that aggregate large populations of billers or consumers, enabling efficient, repeatable distribution through a single technical deployment.
• Align with GTM and Sales Teams. Partner with New Vertical GTM leadership and Sales team members to coordinate joint pipeline management, co-selling efforts, and downstream activation across Flex’s key verticals.
• Launch and Operationalize Partnerships. Work hand-in-hand with Product, Engineering, and Marketing to ensure seamless partner onboarding, technical deployment, and post-launch optimization.
• Feed Market Insights Back to Product. Provide structured market feedback to Product and Engineering teams to shape integration strategy, API roadmap, and partner tooling—ensuring Flex’s solutions remain competitive and scalable.

Key Qualifications

• 10+ years in business development, strategic partnerships, or enterprise sales within FinTech, Payments, or SaaS.
• Proven hunter DNA — demonstrated success in origination-heavy roles where you personally sourced and closed complex, first-of-kind deals.
• Strong experience working with aggregators or platform-based partnerships, ideally involving one-to-many distribution models.
• Full-cycle deal ownership — from outbound prospecting through contracting, launch, and scaling.
• Skilled communicator with executive presence, commercial fluency, and negotiation expertise.
• Operates with urgency, adaptability, and strategic judgment in fast-changing, high-growth environments.
