About the Role

We are hiring a Senior Lifecycle / CRM Manager to own lifecycle marketing across email, SMS, customer journeys, and retention programs. This person will be the day-to-day owner of our lifecycle engine: strategy, execution, testing, reporting, deliverability, and continuous improvement.

This is a hands-on operating role for someone who knows how to build inside Klaviyo, understands DTC retention, and can turn customer behavior into better flows, campaigns, education, and repeat-purchase experiences. It is also a forward-looking role. We want someone excited to work with AI-enabled systems, documentation, QA workflows, and production tools that make lifecycle marketing faster, cleaner, and more scalable without lowering the quality bar.
How You'll Make an Impact

• Own the lifecycle marketing calendar across email and SMS, including campaigns, automations, segmentation, testing, and reporting.
• Build, maintain, and improve Klaviyo flows across post-purchase, replenishment, subscription, education, review generation, cross-sell, winback, and cancellation-save moments.
• Translate customer behavior, feedback, purchase patterns, and cancellation reasons into lifecycle tests and journey improvements.
• Develop a clear testing roadmap for messaging, offers, timing, audience segments, creative angles, and flow architecture.
• Maintain strong deliverability practices, including list hygiene, suppression logic, sender health, template decisions, and QA standards.
• Partner with creative, CX, growth, and analytics to improve the customer journey and increase retention.
• Use AI-enabled workflows to scale lifecycle production, QA, research, documentation, and campaign/flow iteration.
• Build repeatable operating processes so lifecycle work is documented, measurable, and easy to improve over time.
• Report on lifecycle performance and bring clear recommendations to weekly retention reviews.

We're Excited About Your:

• Strong hands-on experience owning lifecycle marketing, CRM, or retention for a DTC brand.
• Deep Klaviyo experience, including flows, campaigns, segmentation, suppression, templates, QA, and reporting.
• Strong understanding of email/SMS deliverability, list health, sender reputation, and lifecycle production best practices.
• Experience building customer journeys that drive retention, repeat purchase, subscription health, reviews, education, and winback.
• Comfort working with retention metrics such as repeat purchase, churn, cohort behavior, LTV, reviews, subscription movement, and flow/campaign contribution.
• Ability to move between strategy and execution: you can build the roadmap, write the brief, check the segment, QA the flow, and explain what happened afterward.
• Strong project management and documentation habits. You create systems that other people can understand and trust.
• Interest in AI-enabled marketing operations, including using AI tools to improve speed, QA, research, production workflows, and operating discipline.
• Clear communication, high ownership, and strong judgment about what actually moves retention versus what only creates activity.

Nice to have:

• Subscription or replenishment-based DTC experience.
• Wellness, health, supplement, or consumable product experience.
• Recharge or similar subscription-platform experience.
• SMS lifecycle experience.
• HTML email or email-build QA experience.
• Experience working with customer support/CX teams to turn customer feedback into better lifecycle journeys.

What great looks like:

• Our lifecycle programs have a clear owner, roadmap, testing cadence, and weekly performance readout.
• Klaviyo is clean, documented, and actively managed.
• Key customer journeys are continuously improved based on performance data and customer signal.
• Deliverability and QA are treated as operating requirements, not afterthoughts.
• AI-enabled workflows help the team move faster while maintaining a high quality bar.
• Lifecycle marketing becomes a durable retention engine across the business.
