The Growth Marketing Manager is responsible for building and scaling a rigorous experimentation program that drives sustainable growth across acquisition, activation, and retention. This role oversees the full lifecycle of growth initiatives—from hypothesis and test design through analysis and scaling—and partners closely with Product, Engineering, and Analytics to turn insights into business impact.

Key responsibilities include:

• Experimentation Roadmap: Design and prioritize A/B and multivariate tests on marketing channels (email, paid, organic), onboarding flows, and product features
• Data Analysis & Insights: Analyze cohort behavior, funnel metrics, and key drop-off points using tools such as Amplitude or Mixpanel; identify high-leverage improvements
• Channel Optimization: Optimize paid and organic acquisition channels (search, social, referral) to improve CAC, activation rates, and early retention
• Cross-Functional Collaboration: Work with Product and Engineering to implement feature flags, tracking instrumentation, and rapid prototypes within the product experience
• Reporting & Communication: Build and maintain dashboards in Looker or Tableau; present test results, learnings, and recommendations to senior leadership
• Test Automation & Scaling: Leverage experimentation platforms (Optimizely, VWO) and develop frameworks for automated rollout, analysis, and scaling of winning variants

Success in this role requires strong proficiency in SQL or Python for data manipulation, excellent project management to juggle multiple concurrent experiments, and a data-driven mindset to continuously iterate on growth levers. Key metrics include improvements in activation rate, retention curves, and LTV/CAC efficiency, as well as the development of a lasting culture of experimentation across the organization.
