Growth Marketing Manager (Lifecycle & Experimentation)

Career Guide
A Growth Marketing Manager (Lifecycle & Experimentation) drives customer growth by improving each step of the customer journey—sign-up, activation, engagement, retention, and reactivation—while running structured experiments to find what works. This role blends marketing strategy, data analysis, and cross‑team coordination to increase revenue and customer lifetime value through measurable, test‑and‑learn programs.

Key Responsibilities

  • Map and improve the customer lifecycle (onboarding, engagement, retention, win‑back) using data and customer insights
  • Plan and run experiments (A/B tests and holdout tests) across channels such as email, in‑app messages, push notifications, SMS, and paid retargeting
  • Define goals, success metrics, hypotheses, and test plans; document results and share learnings
  • Build and optimize automated customer journeys (triggered messages and sequences) to increase activation and repeat usage
  • Partner with Product, Data/Analytics, Engineering, Design, and Sales/Customer Success to ship lifecycle improvements
  • Segment customers (by behavior, needs, or value) and tailor messaging and offers to each segment
  • Improve conversion rates at key points (trial to paid, first purchase, renewal, upgrade) with messaging, offers, and experience changes
  • Monitor performance dashboards and investigate changes in retention, churn, and conversion
  • Ensure data and tracking are reliable (events, attribution, campaign tagging) so results are trustworthy
  • Maintain compliance and best practices around consent, deliverability, and customer communication frequency

Common Skill Gaps

Often Missing Skills
Running experiments with clear hypotheses and correct measurement (not just ‘trying ideas’)Understanding statistical confidence and avoiding misleading resultsReliable tracking setup (events, tagging, attribution) and data quality checksBuilding end‑to‑end automated journeys instead of one‑off campaignsStrong segmentation and personalization beyond basic demographicsCommunicating results clearly to leadership (what happened, why, what’s next)Balancing short‑term conversion wins with long‑term retention and customer trust
Development SuggestionsBuild a small but credible experiment portfolio: choose one lifecycle stage (e.g., onboarding), define 2–3 measurable goals, run a set of tests with clean tracking, and write short case studies that include hypothesis, setup, results, and next steps. Pair this with hands-on tool practice (CRM/automation) and basic SQL to reduce dependence on others for analysis.
