Core Responsibilities

Primary Functions

  • Design and manage end-to-end A/B, multivariate, and personalization experiments to test hypotheses, optimize conversion funnels, and drive measurable business impact using platforms such as Optimizely, VWO, Adobe Target, or equivalent.
  • Develop a prioritized experimentation roadmap aligned to business KPIs (revenue, conversion rate, retention, average order value), using a hypothesis-driven approach and clear success metrics for each test.
  • Calculate required sample sizes and test durations, estimate statistical power, set guardrails for minimum detectable effect, and monitor experiments for validity to ensure reliable results.
  • Execute advanced funnel analysis across acquisition, activation, retention, revenue, and referral stages to identify high-impact optimization opportunities and inform test ideas.
  • Build, maintain, and QA analytics tracking and tag implementation across websites and single-page applications using Google Tag Manager, custom JavaScript, and dataLayer best practices to guarantee accurate experiment measurement.
  • Run exploratory data analysis using SQL, Python, R, or BI tools (Looker, Tableau, Power BI) to segment users, detect behavioral patterns, and derive hypothesis-driven recommendations for experiments.
  • Create and maintain dashboards and automated reports that synthesize experiment results, uplift metrics, and long-term trends for stakeholders and leadership.
  • Lead cross-functional test planning sessions and coordinate technical implementation with frontend engineers to ensure test variants match design and maintain accessibility and performance standards.
  • Conduct session replay, heatmap, and clickstream analysis using FullStory, Hotjar, or similar tools to validate behavioral hypotheses and refine experiment creative and flows.
  • Implement and validate personalization and feature flag rollouts to targeted cohorts, ensuring correct audience definitions and exclusion rules for accurate measurement.
  • Perform post-test analysis to quantify business impact, calculate confidence intervals and credible intervals, and produce clear, actionable insights with recommended next steps.
  • Maintain a backlog and library of past experiments, learnings, and playbooks to scale knowledge across growth, product, and UX teams and avoid duplicate tests.
  • Monitor key web performance and technical SEO metrics (page speed, Core Web Vitals) and collaborate with engineering to prioritize performance-related experiments that impact conversion and search visibility.
  • Apply advanced statistical methods (Bayesian analysis, sequential testing, regression adjustment) when appropriate to increase the sensitivity and interpretability of experiment outcomes.
  • Collaborate with product managers and designers to translate qualitative research and user testing feedback into prioritized, testable hypotheses that address user pain points and conversion barriers.
  • Ensure compliance with privacy, consent, and data governance requirements for experimentation and tracking initiatives, including GDPR, CCPA considerations, and first-party data strategies.
  • Provide technical QA for experiments, including validating variant rendering, event firing, audience targeting, and data integrity across browsers and devices prior to test launch.
  • Train and mentor product, marketing, and analytics teams on experimentation best practices, statistical literacy, and how to interpret test results to foster an experimentation culture.
  • Evaluate and recommend optimization and experimentation tools and technologies (A/B platforms, session replay, analytics, personalization engines) as part of vendor selection and annual reviews.
  • Lead A/B test retrospectives and synthesis workshops to convert insights into roadmap items, product enhancements, and marketing optimizations.
  • Create persuasive presentations and executive summaries that translate technical experiment results into business terms for stakeholders and leadership teams.
  • Investigate and remediate anomalies or tracking issues that could bias experiment results, including bot traffic, instrumentation errors, and inconsistent attribution windows.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis to answer conversion, funnel, or behavioral questions from stakeholders.
  • Contribute to the organization's data strategy and experimentation roadmap, advocating for best practices in measurement, tagging, and data governance.
  • Collaborate with business units to translate data needs into engineering requirements and prioritized experiment specifications.
  • Participate in sprint planning and agile ceremonies within product, growth, and data teams to ensure experimentation tasks are scoped and resourced.
  • Maintain thorough documentation of experiment designs, decision logs, and tagging schemas to support auditability and cross-team knowledge transfer.
  • Monitor experiment platform health, performance, and error logs; coordinate with vendors and engineering to resolve platform-specific issues.
  • Assist with vendor evaluation, procurement, and contract renewals for analytics, testing, and personalization tools.
  • Provide training sessions and office hours to business stakeholders on reading experiment reports, creating testable hypotheses, and interpreting statistical significance.
  • Act as the QA owner for all test-related analytics, ensuring that experiment analytics are correctly instrumented and validated prior to public rollouts.
  • Support continuous improvement of experimentation processes, playbooks, and templates to accelerate test velocity and quality.
