Partner Marketing Manager

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 2026 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

Flex is building out its New Verticals partner marketing function to support emerging product lines beyond Core Rent. This is an early, high-impact role - you will be one of the first dedicated partner marketers supporting New Verticals, working directly with a small team and reporting to the Vice President of Partner Marketing. You'll own marketing programs, sales and partner enablement, and co-marketing execution to help partners in new verticals launch Flex for their customers and drive adoption.This role is ideal for a builder: someone energized by ambiguity, comfortable without a playbook, and excited to define what great partner marketing looks like at the ground floor.

What you'll do

• Build and execute co-marketing programs with New Verticals partners, from program design through asset production and distribution
• Develop partner enablement materials (pitch decks, one-pagers, training content) that help our New Verticals sales teams prospect, win, and launch new partners and deepen engagement with existing partners
• Own the New Verticals partner marketing program roadmap: track what's in flight, what's performing, and what's next, and maintain a regular reporting cadence so stakeholders always have a clear picture of program impact
• Manage partner-facing go-to-market for New Verticals product launches: translate product capabilities into partner messaging frameworks, launch materials, and activation plans that give PMC teams what they need to drive adoption
• Build relationships with marketing contacts at New Verticals partners to surface co-marketing opportunities and deepen engagement
• Coordinate with the Events Marketing Manager on partner-facing events, including pre/post-event communications and follow-up programs
• Analyze program performance across co-marketing, enablement, and channel initiatives; build dashboards, surface insights, and use data to inform what to double down on and what to cut
• Instrument programs with UTMs, tracking links, and CRM tagging in Salesforce so results are always attributable

What you'll bring

• 3-5 years in B2B partner marketing, channel marketing, or field marketing, ideally at a growth-stage technology company
• Proven experience building sales enablement and co-marketing programs with and for external partners, including asset creation, end-to-end campaign management, and measurement
• Proficiency with Salesforce and HubSpot: you can tag campaigns, build reports, set up nurture sequences, and use both tools to connect marketing activity to pipeline outcomes
• Track record of attributing marketing activity to revenue or pipeline outcomes; you care about whether programs actually work
• Comfort operating in a startup or early-function environment; you've built things from scratch and know what that requires
• Strong written communicator who can produce a concise partner brief, a compelling email, and a crisp executive summary
• Curiosity about the competitive landscape; you research how the market works, synthesize partner feedback, and translate insights into smarter program decisions
• Experience & eagerness using AI thoughtfully and strategically in your day-to-day work
