Growth Marketer, Acquisitionnew

About Middesk:

Middesk is building the data and intelligence infrastructure that helps businesses work together with confidence. We started by creating a comprehensive platform for understanding businesses, bringing together authoritative and proprietary data to help customers verify business identities, onboard customers faster, and manage risk throughout the customer lifecycle.

Today, Middesk is used by more than 700 banks and fintechs, and in 2025 we verified more than 7 million companies. We've also expanded beyond business verification to help companies form, register, manage, and maintain their businesses, supporting more than 50,000 companies in setting up over 100,000 accounts required to hire employees, run payroll, and stay compliant.

Middesk came out of Y Combinator, and is backed by Sequoia Capital, Accel, Insight Partners, and Canapi. We're proud to be named on the Forbes Fintech 50 and Best Startup Employers lists.

The Role

Marketing is being completely reinvented. AI is changing how people search, how buyers discover products, and what good growth work even looks like. The marketers who are winning right now are the ones throwing out the old frameworks and rebuilding from first principles — using every modern tool available, living at the edge of AEO and agentic search, and figuring out how to get in front of the right people before anyone else does.

That’s the context for this role. You’ll own how Middesk gets found. SEO in a world where AI sits between every query and every result. Paid acquisition that actually converts. Website experiences that move people through. Experiments that run fast and teach you something real. You’ll build the systems, not just execute within them.

This is a role for someone who has spent the last few years learning inside a strong growth org and is ready for real ownership. You won’t be one of dozens. You’ll help define how growth works at Middesk.

We follow a hybrid work model, and for this role, there is an expectation of 3 days per week in our NYC or SF office. Candidates should be based within a commutable distance, as we believe in the value of in-person collaboration and building strong team connections while also supporting flexibility where possible.

What You’ll Own

• Inbound growth channels across SEO, AEO, paid acquisition, and website conversion

• Growth experiments across acquisition, conversion, and pipeline generation with clear measurement and fast iteration

• Analytics and reporting infrastructure so the team makes decisions based on data

• Campaign execution in partnership with Product Marketing to bring product launches and content to market

• Distribution strategy for content, insights, and Middesk’s point of view in market

• Emerging channel strategy, spotting what’s working before it becomes obvious

What We’re Looking For

• 2–5 years in growth marketing, demand generation, or performance marketing, ideally in B2B SaaS or fintech

• Familiarity with SEO, AEO, paid acquisition, lifecycle marketing, or conversion optimization

• Strong analytical instincts and comfort building measurement frameworks from scratch

• High ownership mentality and comfort operating with ambiguity

• Intellectual curiosity about where marketing is going, not just where it has been

• Excited to build, not just optimize

Bonus Points

• Experience at companies like Ramp, Mercury, Brex, Rippling, Vanta, or Retool

• Hands-on experience with AI-enabled marketing workflows or agentic tooling

• Background in consulting, analytics, or structured problem-solving environments

• You’ve been thinking about AEO and agentic search before it was a talking point
