B2B Lifecycle Marketing Manager (contract)

Role

We are hiring a B2B Lifecycle Marketing Manager (contract-to-hire) to own and execute lifecycle marketing across activation, engagement, retention, and expansion. The role is hands-on and technical, responsible for designing rules-based and algorithmic lifecycle programs powered by HubSpot and AI-enabled personalization.

Key Responsibilities

• Own end-to-end B2B lifecycle marketing: demand-gen nurture flows for net-new prospects, customer programs for upsell/expansion, partner lifecycle programs, and ad-hoc sends (product launches, experiments, GTM moments).
• Design intelligent lifecycle programs that dynamically determine who to message, when, where (email, push, emerging CRM channels), and what content to send based on behavior and context.
• Apply AI and automation for content generation, personalization, segmentation, and decisioning within HubSpot.
• Build and optimize nurture flows with branching logic, lifecycle segmentation, and strong deliverability practices.
• Create experimentation frameworks that measure incremental impact and avoid over-attribution.
• Partner closely with Data, GTM, and Product teams to ensure messaging is native, timely, and valuable.

Requirements

• 5+ years of experience in B2B lifecycle / CRM marketing, growth, or a related discipline.
• Deep, hands-on expertise with HubSpot, including marketing automation, lifecycle segmentation, nurture flows, and branching logic.
• Proven experience with email deliverability, list hygiene, and sender reputation.
• Strong analytical instincts and comfort using data to prioritize and measure impact.
• Experience building adaptive, evolving lifecycle systems rather than static journeys.
• Hands-on experience applying AI and automation to content creation, personalization, segmentation, and decisioning logic.
• Comfort operating in ambiguity and designing systems that improve over time.
• Proven experience using vibe coding (AI-assisted building) to increase effectiveness.

Success Looks Like

• Lifecycle marketing becomes a measurable, causal growth lever for activation, retention, and revenue.
• Users experience lifecycle messaging as relevant, well-timed, and valuable rather than noisy or generic.
• Cross-functional teams have strong confidence in lifecycle contribution beyond surface-level metrics.

Location & Commitment

• Hybrid, contract-to-hire role based in San Francisco; open to Boston for the right candidate.
