AI-Driven Growth Engineer for Demand Gen

HARVEY; New York (NY); On-site; USD 136,000 - 204,000; Full time

Job summary

Harvey in New York seeks a Marketing Engineer who sits at the intersection of growth strategy and world‑class AI execution. You will own AI and automation use cases to improve demand generation velocity and pipeline performance, partnering with marketing leadership to ship high‑leverage experiments.

You’ll build AI workflows, integrate with Marketo, Salesforce, and web platforms, and design experiments to unlock growth. Experience with LLM APIs and analytics is essential.

Qualifications

• 4+ years of experience in growth engineering, marketing engineering, GTM engineering, or a technical role within a marketing/growth function at a B2B SaaS company.
• Hands‑on experience building with AI — you use tools like Claude Code, Cursor, or equivalent as part of your daily workflow, not just as something you build on top of.
• Experience working with LLM APIs or AI‑powered tools to generate content, automate workflows, or optimize marketing performance.
• Familiarity with marketing automation platforms (e.g., Marketo, HubSpot), CRMs (e.g., Salesforce), workflow/automation tools (e.g., Clay, n8n, Zapier, Make), and analytics/experimentation tooling (e.g., Amplitude, Mixpanel, Segment, PostHog, GA4).
• A builder mentality, comfortable operating in ambiguity, shipping iteratively, and taking ownership of 0→1 projects.
• Strong analytical skills with the ability to design experiments, own attribution, and translate data into decisions.
• Cross‑functional collaboration: work closely with internal teams across data science, marketing operations, performance marketing, product marketing, and sales to ensure campaign success. Drive alignment on priorities and share insights to refine strategies.

Responsibilities

• Own the identification, scoping, and implementation of AI and automation use cases that improve demand generation velocity, campaign operations, pipeline conversion and more.
• Build and maintain AI workflows from automated content creation to intelligent audience targeting and personalization at scale.
• Design and deploy automation workflows (e.g., Claude, Clay, n8n, or equivalent) that eliminate manual work across the demand gen stack, integrating with Marketo, Salesforce, web CMS, and digital platforms.
• Build and run experimentation infrastructure: A/B tests, landing pages, and conversion‑flow changes, directly on harvey.ai and campaign surfaces, not just backend automation.
• Manage the cost and efficiency of automated workflows.
• Collaborate with Marketing Operations, Content, and Performance Marketing to translate strategic marketing needs into technical solutions.
• Continuously evaluate emerging AI capabilities, including new models, agent frameworks, and MCP integrations, and prototype applications that give Harvey's marketing team a competitive edge.
