About the Job

Requirements

  • Hands-on experience in a consumer subscription app involving paywalls, trials, renewals, or pricing.
  • Comfort working hands-on with JSON, HTML, CSS, and some JavaScript, often alongside AI agents; SQL is expected.
  • A degree in a quantitative or technical field, or equivalent work experience.
  • A practical grasp of experiment statistics, including sample size and minimum detectable effect, sample ratio mismatch, peeking, diluted traffic, and pitfalls in segment analysis.
  • The ability to verify what actually serves users, such as the live configuration and real checkout, and to state exactly what was and was not verified.
  • Clear written communication in English and ability to work in a remote, asynchronous team.

Responsibilities

  • Build paywall, checkout, and onboarding variants using JSON configuration, HTML, CSS, and JavaScript, and ship them through code review and continuous integration.
  • Set up and launch A/B tests, including allocation and targeting, while avoiding conflicts with tests already running.
  • Design and run tests on price points, introductory offers, and paywall design across the Web2App funnel.
  • Own in-app cross-sell surfaces, deciding where offers appear, when they appear, and to whom.
  • Grow cross-sell exposure, conversion, and lifetime value without cannibalizing web upsells or harming retention.
  • Run in-app experiments on placement, timing, offers, and copy, and track cross-sell revenue per active user.
  • Build dashboards, analyze experiment results, and write readouts that conclude with recommendations.
  • Track paid conversion, lifetime value, average revenue per user, and upsell and cross-sell attach rates.
  • Use paid-ad acquisition data and creative themes to match offers to arriving users.
  • Support willingness-to-pay segmentation by matching offers to users to grow lifetime value and return on ad spend.
  • Study competitors’ onboarding and monetization flows and identify ideas worth testing.
  • Build lifetime-value projections for new offers and experiment results so decisions reflect long-term value as well as first-week revenue.
  • Translate experiment learnings into subsequent monetization roadmap bets.
  • Maintain and regularly prune the roadmap based on data.
  • Work with AI coding and analysis agents daily and check their output before it reaches production.
  • Document experiment specifications, launch notes, and readouts for asynchronous team use.
  • Within the first 30 days, launch at least three pricing, packaging, or cross-sell experiments end to end.
  • Within the first 30 days, learn the web funnel and in-app cross-sell surfaces well enough to propose the next quarter’s test plan.

Desired Qualifications

  • Experience designing and running A/B tests.
  • Experience in onboarding or conversion rate optimization.
  • Experience with pricing research methods such as Van Westendorp, Gabor-Granger, and conjoint analysis.
  • Experience with in-app experimentation tools.
  • A background in data science or machine learning.
  • An interest in behavioral science.
  • Python proficiency.
