About the Role

We are hiring an AI-first Retention Product Manager to own the customer's post-purchase product experience and the operating systems behind our retention programs. This includes app and portal onboarding, subscription management, post-purchase education, loyalty and referral programs, and the AI-enabled production and QA workflows that power our lifecycle marketing.

This is a hybrid role for someone with strong lifecycle fundamentals who has grown into product thinking: defining requirements, shipping improvements with engineering, instrumenting outcomes, and treating AI as a core capability rather than a tool they occasionally use. You can build a Klaviyo flow yourself - but you'd rather build the system that produces a hundred of them reliably.
How You'll Make an Impact

• Own retention-impacting product surfaces: app and portal onboarding, subscription management, account experience, and post-purchase education.
• Design, build, and operate AI-enabled production systems for retention - briefing, email/flow build, QA, research, and reporting workflows.
• Translate retention strategy into product requirements and ship improvements in partnership with product, engineering, and design.
• Run experiments that span product and lifecycle touchpoints: in-app prompts paired with email/SMS journeys, cancellation-save experiences, education sequences.
• Build and operate loyalty, referral, VIP, and advocacy programs - platform selection, integration, and lifecycle activation.
• Execute hands-on in Klaviyo when needed: flows, segmentation, QA.
• Instrument retention product work so impact is measurable: event tracking, dashboards, experiment readouts.
• Document systems and processes so workflows scale beyond you.

We're Excited About Your:

• Experience spanning lifecycle marketing and product management - you've owned a product surface or shipped product work, not just campaigns.
• A demonstrated AI-native working style: you build with AI tools daily, design workflows around them, and know where they fail.
• Technical fluency: APIs, webhooks, integrations, automation platforms, and basic data work. You don't need engineering for everything.
• Solid Klaviyo (or equivalent ESP) skills - enough to execute and to collaborate deeply with lifecycle marketing.
• Strong experimentation instincts: hypothesis, test design, measurement, honest readouts.
• High ownership and clear judgment about what moves retention versus what only creates activity.

Nice to have:

• Subscription or replenishment-based DTC experience, especially with a companion app or customer portal.
• Wellness, health, supplement, or consumable product experience.
• Loyalty or referral platform experience.
• Light scripting or no-code/low-code build experience.
• Experience standing up AI/automation workflows for a marketing or CX team.

What great looks like:

• Retention product surfaces have a clear owner, roadmap, and measurable improvement cadence.
• AI-enabled production systems run reliably with documented QA - operating infrastructure, not experiments.
• Loyalty and referral move from idea to tested program without new headcount.
• Product and lifecycle stop being separate lanes: experiments routinely span both.
