Job Description

Responsibilities

  • Own end-to-end lifecycle strategy and execution: map customer journeys, define key stages (onboarding, activation, habit formation, expansion, renewal, win-back), and build multi-channel automated flows
  • Develop and launch high-impact campaigns and nurtures (welcome series, product education, milestone triggers, re-engagement, upsell/cross-sell, churn prevention, and subscription reactivation)
  • Build and refine audience segments using behavioral, usage, and subscription data to deliver hyper-personalized experiences
  • Partner closely with product, data/analytics, customer success, and engineering teams to align on triggers, messaging, and technical implementation
  • Set up, monitor, and optimize experiments (A/B, multivariate) to continuously improve open rates, click-through, conversion, retention, expansion revenue, and churn metrics
  • Analyze performance using SQL, Amplitude/Mixpanel, and other tools to identify drop-offs, opportunities, and ROI; report on key KPIs (activation rate, D30/D90 retention, expansion revenue, churn rate, LTV uplift, NRR)
  • Collaborate on content creation (copy, creative assets) and ensure brand voice consistency across all lifecycle touchpoints
  • Maintain and evolve the lifecycle marketing roadmap in line with product launches, seasonal campaigns, and business priorities
  • Champion best practices in personalization, frequency management, deliverability, privacy/compliance (GDPR, CCPA), and inclusive messaging

Requirements

  • 4–7+ years of experience in lifecycle marketing, retention/growth marketing, CRM marketing, or customer marketing (B2C e-commerce, SaaS, fintech, or consumer tech strongly preferred)
  • Proven track record owning lifecycle programs that drove measurable improvements in retention, engagement, expansion, or revenue (please share case studies or results in your application)
  • Hands-on expertise with marketing automation & CRM platforms (Braze, Iterable, Customer.io, Klaviyo, or similar)
  • Strong analytical skills — comfortable writing SQL for cohort analysis, funnel deep-dives, and behavioral metrics
  • Experience building and testing multi-channel journeys (email + SMS + push + in-app)
  • Excellent copywriting and storytelling skills — you can craft compelling, customer-centric messaging that converts
  • Data-driven mindset with a bias for action and rapid iteration
  • Comfortable working in ambiguous, fast-paced environments with cross-functional stakeholders

Preferred

  • Experience with advanced segmentation and personalization using tools like Segment, mParticle, or Census
  • Background in product-led growth (PLG) environments or hybrid PLG/subscription models
  • Familiarity with loyalty/rewards programs, referral mechanics, or subscription optimization (pricing, billing, upgrades/downgrades)
  • Exposure to AI-driven personalization or predictive churn modeling
  • Knowledge of web/mobile analytics (Google Analytics 4, Amplitude, Mixpanel) and experimentation platforms (Optimizely, VWO, Eppo)
