Senior Director, Business Development

role at

Flex .

Flex is a growth‑stage, NYC‑headquartered FinTech company creating the best rent‑payment experience. Paying rent on time is expensive, inflexible, and difficult – it’s 2025, and we’re here to change that. Flex enables users to pay rent throughout the month on a schedule that fits their finances and budget. Our mission is to empower as many renters as possible with flexibility over their most significant recurring expense.

About The Role

We’re looking for a Senior Director 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 high‑impact, outward‑facing role measures performance 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 by identifying whitespace opportunities and prospective partners, driving outbound prospecting, executive‑level relationship development, and creative deal sourcing to build a highly qualified pipeline of net‑new strategies.

Structure and close company‑defining deals, leading the full lifecycle of strategic negotiations—including commercial structure, economics, exclusivity, data, integration scope, and go‑to‑market commitments.

Develop partnership theses and strategic roadmaps in collaboration with Executive Leadership, Product, and Strategy to accelerate Flex’s long‑term vision, building business cases, quantifying impact, and prioritizing opportunities.

Design joint value propositions and GTM motions, translating market insights and partner needs into differentiated, win‑win offerings, co‑selling models, incentive structures, and marketing strategies that drive adoption, activation, and long‑term engagement.

Align and orchestrate internal stakeholders, partnering with GTM and Sales leaders to ensure strategic partnerships are understood, supported, and effectively activated in the field.

Launch, scale, and deepen strategic relationships, overseeing the successful launch and early‑stage execution, ensuring seamless onboarding, technical deployment, and operational readiness.

Feed strategic market insights back to the business, providing outside‑in feedback to Product, Strategy, and Executive teams on partner needs, market trends, and competitive dynamics.

Key Qualifications

10+ years in business development, strategic partnerships, or enterprise sales within FinTech, Payments, or SaaS.

Explicit C‑level hunting orientation – demonstrated success building relationships directly with CEOs, CFOs, COOs, CROs, and other senior executives at large enterprises, converting those relationships into high‑impact strategic deals.

Proven hunter DNA – successful in origination‑heavy roles, personally sourcing and closing complex, first‑of‑kind or highly strategic deals. Deep experience structuring and negotiating multi‑stakeholder partnerships.

Full‑cycle deal ownership from thesis development to launch and multi‑year scaling. Skilled communicator with executive presence, commercial fluency, and strong negotiation capabilities.

Operates with urgency, ownership, and strategic judgment in fast‑changing, high‑growth environments; able to navigate ambiguity and build structure where none exists.

Compensation

The compensation range for this role will be commensurate with the candidate’s experience and Flex’s internal leveling guidelines and benchmarks. This is a commission‑earning role. On‑target earnings range from $265,000 to $365,000.

Benefits

Competitive medical, dental, and vision from Day 1.

Company equity.

401(k) plan with company match (match begins in 2026).

Unlimited paid time off + 13 company paid holidays.

Parental leave.

Flex Cares Program.

Free Flex subscription.

Unlimited PTO for non‑US employees.
