Product Manger, Growth - Lifecycle

Cantina • San Francisco, CA

1d • $150,000 - $180,000

About The Position

Cantina Labs is a social AI company developing advanced real-time models for expression, personality, and realism. They are seeking a Lifecycle Product Manager to own how their platform, Cantina, reaches users outside the app and brings them back. This role involves managing the end-to-end user journey across email, push, and in-product messaging, as well as the associated landing and post-click experiences. The Product Manager will develop a deep understanding of user behavior to create a lifecycle strategy focused on growing activation, retention, and resurrection. This is a hands-on position with high visibility, requiring strategy development, journey implementation, experiment execution, and stakeholder management.

Requirements

• 6+ years in product management, growth, lifecycle/CRM, or retention — ideally in a consumer mobile or AI product operating at scale.
• Demonstrated ownership of lifecycle or engagement programs that moved a real business metric (activation, D30 retention, resurrection, or conversion), with the analysis to prove it.
• Strong quantitative fluency: comfortable writing your own SQL and working in a BI/analytics tool (Mixpanel, Amplitude, Hex, Looker, or similar) to build funnels, cohorts, and retention curves without waiting on a queue.
• Hands-on experience with a lifecycle/CRM platform (Braze, Iterable, Customer.io, or similar) — segmentation, triggered canvases, personalization, and deliverability.
• Rigorous experimentation judgment: you understand holdouts, incrementality, sample sizing, and the difference between a delivery metric and a value metric.
• Technical and product fluency across event and identity models, APIs, deep linking, and push/email infrastructure — enough to design a system with Engineering. Coding not required.
• Excellent written communication and cross-functional influence, with a track record of aligning senior stakeholders across Product, Engineering, Data, Design, and Marketing.
• Craft-level instinct for messaging: you can write the copy, critique the journey, and tell when a notification is helpful versus annoying.

Nice To Haves

• Experience with AI/consumer-social products
• Experience with localization or multi-market lifecycle
• Experience building lifecycle tooling or self-service platforms with Engineering

Responsibilities

• Own the lifecycle strategy and roadmap for Cantina's owned channels, mapping journeys across onboarding, activation, continuation, retention, resurrection, and monetization.
• Lead the design, launch, iteration, and optimization of templates and journeys across email, push, and in-product messaging — including the deep-linked landing and post-click product experiences that complete the loop.
• Optimize the lifecycle portfolio, not just individual sends: improve message inventory, relevance, personalization, prioritization, and per-user frequency so users get fewer, better-timed messages.
• Build a deep, evidence-based picture of the user journey — combining product analytics, cohort and funnel analysis with qualitative signals like session reviews, support themes, and user research — and use it to find where users stall and what would move them.
• Design and run experiments (A/B tests, holdouts, incrementality reads) and hold the bar on measurement: retained activity and incremental value, not opens and clicks.
• Partner with the Data team to build the measurement system behind lifecycle — instrumentation, eligibility and audience definitions, dashboards, and experiment readouts.
• Partner with Engineering to ship campaigns end to end: triggers, personalization payloads, deep links, and the in-product surfaces each journey lands on.
• Define the operating model — intake, templates, approvals, QA, and quality standards — so lifecycle scales across teams without channel chaos or user fatigue.
• Set and communicate strategy to senior stakeholders, translating a messy portfolio into a clear multi-quarter direction and defending tradeoffs with data.

Benefits

• Competitive salary and generous company equity
• Medical, dental, and vision insurance – 99.99% of premiums covered by Cantina
• 42 days of paid time off, including: 15 PTO days, 10 sick days, 15 company holidays, 2 floating holidays
• Generous parental leave & fertility support
• 401(k) retirement savings plan
• $500/month lifestyle spending account
• Complimentary lunch and snacks for in-office employees
• One Medical membership
