Role overview

A senior individual-contributor position embedded with demand generation, digital, and marketing operations to build the inbound funnel. The role ships AI agents, automations, and integrations that compress lead-response time, sharpen lead scoring, and personalize the buyer journey from first touch to sales handoff. Success is measured by faster speed-to-lead, higher conversion rates, and teams that no longer perform the manual version of this work.

Responsibilities

• Build automations that route, score, and respond to inbound leads in minutes.
• Design and deploy AI agents such as chat, form-follow-up, and lead-qualification assistants.
• Integrate website personalization, dynamic forms, and content recommendations tied to visitor intent and account data.
• Integrate marketing automation, CDP, enrichment, intent data, and CRM to keep lead data accurate at every handoff.
• Automate content production, on-page optimization, and SEO performance tracking.
• Build evaluation harnesses for lead-scoring accuracy, chat-agent quality, and routing correctness.
• Implement human-in-the-loop review, logging, and rollback for customer-facing outputs.
• Coach marketing operations and demand generation on AI adoption and produce playbooks and reusable templates.

Requirements

• Senior-level hands-on builder comfortable shipping AI agents and automations against real funnel metrics.
• Deep familiarity with marketing automation, CDP, enrichment, intent data, and CRM platforms (for example Marketo or HubSpot, Salesforce, Segment, ZoomInfo or Clearbit, and 6sense).
• Ability to design evaluation harnesses and measure quality against human baselines.
• Strong coaching skills for non-technical marketers without relying on positional authority.

Nice to have

• Practical experience fine-tuning or heavily customizing models for production use cases.
• Background in B2B or enterprise SaaS with brand-safety and compliance constraints on automated outputs.
• Experience with AI system practices such as prompt evals, benchmarking, and regression testing.

Benefits and work setup

• U.S. base salary range of $132,000–$182,000 USD, varying by location.
• Benefits package including medical, dental, and vision coverage; 401(k) with match; life and disability insurance; flexible time off; paid holidays and sick time; parental and grandparent leave; RSUs and ESPP; wellness coaching and gym reimbursement; home office allowance; and mobile phone reimbursement.
