Job description

Series B AI Platform | New York | Competitive Package

We're partnered with one of the most exciting AI companies in the market right now. Having just closed a $40M Series B backed by some of the most respected names in tech investment, they are building the infrastructure layer that allows teams of humans and AI agents to work together — and they're scaling fast. 3,000+ organizations globally. 300,000+ agents deployed. 70% weekly active users. The traction is real.

With a strong growth marketing function already in place, they are now adding a second operator to the team to own pipeline generation across their target markets. This is a newly created role, reporting into the Head of Marketing, sitting at the heart of a lean and high-performing go-to-market function.

This is not a role for someone who waits to be briefed. You'll design campaigns, build the assets yourself, run experiments every week, and be directly accountable for the qualified pipeline you generate.

The Growth Marketer will:

• Run 3-5+ demand generation experiments per week across LinkedIn, email, paid social and paid search — with a disciplined approach to testing, iteration and learning
• Own a pipeline number, with every campaign traceable to qualified opportunities for the sales team
• Build and manage target account lists in close coordination with RevOps and Sales, mapping the right contacts within priority accounts
• Design and execute full campaign sequences end-to-end: strategy, copy, asset creation and reporting
• Build assets independently — landing pages, email sequences, one-pagers, LinkedIn creatives — leveraging AI tools to move fast without sacrificing quality
• Own CRM hygiene and performance tracking in HubSpot, reporting on what is and isn't working
• Work closely with the broader marketing team to ensure all campaigns are on-brand and consistent with the wider messaging strategy

Required Skills and Experience:

• Proven experience in demand generation, growth marketing or a closely related role within a B2B tech environment
• Ability to own campaign execution completely end-to-end, without reliance on a creative or support team around you
• Hands-on experience running ABM-style campaigns: ICP-led targeting, account mapping and personalized outreach sequences
• Strong analytical instincts — comfortable reading your own data, drawing conclusions quickly and adjusting course
• Fluent across the core channels: LinkedIn, paid social, email and paid search
• An AI-native operator — you use AI tools daily as a natural part of how you work
• Experience across more than one geographic market, with an understanding that US and European campaigns require different instincts, not just different copy

Why You'll Love It:

• Join one of the most talked-about AI companies in the market, fresh off a landmark Series B raise with world-class investors
• A genuine greenfield opportunity — this is a newly created role where your impact on pipeline will be visible and measurable from day one
• Work alongside a highly talented, low-ego team that moves fast and takes the craft seriously
• Competitive compensation package with meaningful equity upside at an early-stage, high-growth company
• In-person culture in either San Francisco or New York

This opportunity will appeal to a commercially driven, hands-on growth marketer who thrives in high-velocity environments and wants to be a key part of building something genuinely important. If you have the drive, the technical toolkit and the taste to do this well — we'd love to hear from you.

Due to the volume of applications, we are only able to respond to candidates selected for interview.
