Main Responsibilities

• Develop data-driven hypotheses for in-app A/B tests across key marketing funnels (onboarding, paywall, upsell, retention) and maintain a structured testing roadmap and backlog;
• Plan, prioritize, and manage the full A/B testing lifecycle — from hypothesis through execution to results analysis;
• Work cross-functionally with designers, developers, analysts, and marketing stakeholders to scope, build, and launch experiments;
• Define success metrics and KPIs for each test; ensure proper data tracking and instrumentation is in place for accurate measurement;
• Monitor live experiments for data quality, statistical significance, and anomalies; proactively flag and remove blockers that could delay launches or compromise results;
• Analyze test outcomes and synthesize findings into clear, actionable recommendations; communicate status and results to relevant stakeholders throughout the process;
• Create and maintain comprehensive documentation for each experiment (hypothesis, setup, audience, duration, results, next steps).

Qualifications

• Experience in digital marketing, CRO, or growth — with hands-on A/B testing involvement;
• Solid understanding of experimentation methodology: hypothesis design, sample sizing, statistical significance, common pitfalls;
• Familiarity with mobile app development processes and release cycles;
• Experience working with analytics and tracking tools (e.g., Amplitude, Firebase, Mixpanel or similar);
• Strong communication skills (verbal and written) — able to translate test results into clear narratives for both technical and non-technical audiences;
• Data-driven decision-making mindset with strong analytical thinking;
• Rigorous attention to detail, especially around data accuracy and test setup;
• Ability to manage multiple experiments in parallel in a fast-paced environment;
• Self-motivated and self-managing — comfortable owning the process end to end;
• Solid organizational skills, including prioritization, time management, and stakeholder alignment.
