Founding Marketer

Job Description

FOUNDING MARKETER | AI STARTUP | NYC

Build the marketing function. From zero.

We’re looking for a Founding Marketer to join a fast-growing AI platform transforming how major construction capital programmes are managed.

Location : Midtown Manhattan

Hybrid: Typically 3 days per week in office

Sector: AI | B2B SaaS | Construction Tech

This is the first marketing hire.

No inherited team. No agency doing the work. No established playbook.

You’ll work directly with the founders to define the message, build the brand and create the marketing engine that drives the company’s next stage of growth.

You’ll own:

\n
• Content – case studies, customer stories, blogs, newsletters and LinkedIn
\n
• Messaging, positioning and brand
\n
• Conferences and events from strategy through to execution
\n
• Paid campaigns across LinkedIn, Google and Meta
\n
• Creative growth experiments and AI-powered marketing workflows
\n
• Sales collateral, demo materials and objection handling
\n
• Turning complex AI technology into a compelling story for enterprise buyers
\n

We’re looking for:

\n
• 3–7 years’ B2B marketing experience
\n
• B2B SaaS/startup experience
\n
• Evidence of actually creating great marketing content
\n
• Hands-on paid advertising experience
\n
• A genuine 0-to-1 mentality
\n
• The confidence to operate independently and move quickly
\n

Experience across AI, construction tech, proptech, AEC, data infrastructure or enterprise software would be a major bonus.

This isn't a role where you'll inherit someone else's marketing machine.

You get to build it.

And as the business grows, there’s a clear opportunity to build and lead the marketing team around you.
