Senior Director, Business Development

Flex is a growth-stage, NYC headquartered FinTech company that is creating the best rent payment experience. It’s hard to believe that it’s 2025 and paying rent on time is expensive, inflexible, and difficult. We’re here to change that! Flex enables our users to pay rent throughout the month on a schedule that better fits their finances and budget. Our mission is to empower as many renters as possible with flexibility over their most significant recurring expense. After deliberately keeping a stealth profile as we built up unprecedented investor support and an enthusiastic user base, we are looking for motivated individuals to help us keep our mission growing. Will you be a part of the team?

About the Role

We’re looking for a Senior Director, Business Development who lives for the hunt — a strategic seller and deal architect who knows how to open doors, build conviction, and close complex partnerships that unlock outsized enterprise value. You’ll originate and lead de novo partnership opportunities that expand Flex’s strategic footprint, create new revenue streams, and deepen our distribution moat. 

This is a high-impact, outward-facing role where performance is measured in step-change outcomes: new strategic logos, scaled distribution, and company-defining partnerships. Reporting to the SVP of Business Development & Strategic Partnerships, you’ll own the full deal lifecycle — from thesis development and pipeline creation to executive alignment, negotiation, launch, and multi-year scaling.

This role offers hybrid flexibility in NYC or San Francisco (relocation assistance available).

What you’ll do

• Originate and Build De Novo Strategic Partnerships: Proactively identify whitespace opportunities and prospective partners where Flex can unlock substantial mutual enterprise value. Drive outbound prospecting, executive-level relationship development, and creative deal sourcing to build a highly qualified pipeline of net-new, strategic opportunities.
• Structure and Close Company-Defining Deals: Lead the full lifecycle of strategic negotiations—including commercial structure, economics, exclusivity, data and integration scope, and go-to-market commitments. Partner closely with Legal, Finance, Risk, and Operations to craft agreements that are both innovative and scalable, and that materially move the needle for Flex.
• Develop Partnership Theses & Strategic Roadmaps: Collaborate with Executive Leadership, Product, and Strategy to define where and how partnerships can best accelerate Flex’s long-term vision. Build business cases, quantify impact, prioritize opportunities, and develop clear multi-year roadmaps for Flex’s most important partners.
• Design Joint Value Propositions & GTM Motions: Translate market insights and partner needs into differentiated, win-win offerings. Shape joint value propositions, co-selling models, incentive structures, and marketing strategies that drive adoption, activation, and long-term engagement across partner channels.
• Align and Orchestrate Internal Stakeholders: Partner with GTM and Sales leaders to ensure strategic partnerships are understood, supported, and effectively activated in the field. Coordinate cross-functional teams across Product, Engineering, Marketing, and Customer Operations to align on objectives, timelines, and success metrics.
• Launch, Scale, and Deepen Strategic Relationships: Oversee the successful launch and early-stage execution of key partnerships, ensuring seamless onboarding, technical deployment, and operational readiness. Establish governance models, run executive check-ins and QBRs, and systematically identify expansion and upsell opportunities.
• Feed Strategic Market Insights Back to the Business: Provide structured, outside-in feedback to Product, Strategy, and Executive teams on partner needs, market trends, and competitive dynamics. Help shape Flex’s platform roadmap, integration strategy, and enterprise capabilities to better serve and grow our most important partnerships.

Key qualifications

• 10+ years in business development, strategic partnerships, or enterprise sales within FinTech, Payments, or SaaS.
• Explicit C-level hunting orientation — demonstrated success initiating and building relationships directly with CEOs, CFOs, COOs, CROs, and other senior executives at large enterprises, and converting those relationships into high-impact strategic deals.
• Proven hunter DNA — demonstrated success in origination-heavy roles where you personally sourced and closed complex, first-of-kind or highly strategic deals with large enterprises.
  Deep experience structuring and negotiating multi-stakeholder partnerships
