Growth Marketing Manager

The Role
We’re looking for a Growth Marketing Manager to build and own the pipeline engine at Class 3. Our go-to-market motion is working. We have strong traction with institutional clients across real estate, infrastructure, and financial services, and now we need someone to systematize and scale it.

This is a builder role. You’ll set up the systems, own the channels, and drive the volume and quality of leads coming into the funnel. Our technical founders handle domain credibility and relationship depth; you handle the mechanics that get them in front of the right people at the right time. We expect you to build with AI-native tooling from day one, using LLMs and automation platforms to move fast, while injecting your own creativity and strong communication skills to get Class 3’s message out.

You’ll report to the CEO and work closely with sales and product leadership to align marketing with pipeline targets.

About You
You know how to generate demand for a technical B2B product in a niche market. You think in accounts, not audiences. Our ICP is narrow and well-defined, and you know how to run precision outreach against it. You’re creative enough to make content that earns attention from people who aren’t looking to be marketed to, systematic enough to build the infrastructure that makes it repeatable, and clear-eyed enough to know the difference between volume and quality in a pipeline.

You welcome AI as a working tool, and may have used Claude, ChatGPT, Gemini, or similar LLMs to draft campaigns, research accounts, synthesize competitive intel, or build workflows. You may have wired together automation pipelines in n8n, Zapier, or Make to eliminate manual steps across prospecting, enrichment, and outreach. You see every repetitive marketing task as something that could be automated or improved.

You care about the problem. You don’t need a background in climate science, engineering, or real estate. But you’re intellectually curious about the domain and motivated to learn it deeply. You’ll immerse yourself in the language of hazard modeling, asset resilience, and institutional risk so you can communicate credibly with technical buyers and the organizations they serve.

What You'll Do

• Own the lead generation function end-to-end: strategy, systems, execution, and reporting
• Design and run account-based marketing programs targeting a well-defined ICP across institutional real estate, asset management, infrastructure, and engineering verticals globally
• Build and manage outbound campaigns across LinkedIn and cold email against a defined account list, with continuous A/B testing on copy, targeting, and sequencing
• Use LLMs (Claude, ChatGPT, Gemini) across the marketing function: ICP research and refinement, account intelligence gathering, campaign copy drafts, content repurposing, and competitive analysis
• Leverage AI-augmented marketing automation pipelines (n8n, Zapier, or Make) integrated with CRM workflows to automate lead enrichment, scoring, and routing
• Lead the evolution of the Class 3 marketing website: content updates, messaging iterations, and conversion optimization
• Manage and evolve our LinkedIn content strategy, both company presence and support for founder thought leadership, including content calendars, multi-week content arcs, and performance tracking
• Coordinate conference participation: identify relevant events, manage logistics, develop materials, and maximize lead capture on the ground; may require travel.
• Develop product marketing collateral (one-pagers, pitch decks, case studies, spec sheets) in close collaboration with product and design
• Deepen domain fluency in climate risk, natural hazards, and institutional resilience to shape messaging that resonates with technical and executive audiences alike
• Track and report on pipeline contribution, channel performance, and conversion metrics

What We're Looking For

• 3–5 years in a B2B marketing or demand generation role, ideally at an early-stage company where you owned the function
• Demonstrated ability to build ABM or precision outbound programs that produce qualified pipeline, not just activity metrics
• Demonstrated experience using LLMs (Claude, ChatGPT, Gemini) as working tools for content creation, research synthesis, and campaign development, understanding best practices and when human intervention and interaction is critical
• Strong writer: you yourself can produce crisp, credible copy for an audience that will see through anything generic
• Hands-on experience building automation workflows (n8n, Zapier, or Make) that connect marketing tools, enrich data, and reduce manual execution time
• Experience managing LinkedIn content strategy and understanding of what drives engagement with technical or institutional audiences
• Hands-on proficiency with relevant tools: CRM and marketing automation platform, Sales Navigator, Apollo.io or Clay, email sequencing tools, and AI/automation platforms (Claude, n8n/Zapier/Make)
• Genuine curiosity about climate risk, natural hazards, and the built environment; willingness to learn the domain deeply enough to speak the language of technical buyers
• Comfortable working in a fast-moving environment where the playbook is still being written
• US-based (New York or San Francisco, hybrid); willing to travel for conferences and client events

First 90 Days

• Build ICP segmentation and target account list across priority verticals
• Stand up CRM workflows, lead routing, and pipeline reporting
• Launch at least two outbound sequences with A/B testing in place
• Establish LinkedIn content cadence for both company presence and founder thought leadership
• Implement at least one AI-powered workflow (lead enrichment, outbound personalization, or content production) that demonstrably reduces manual effort
• Deliver 8–12 qualified meetings per month by end of month three
