About the Role

Lead the Experimentation & Failure team, reporting to the CITO. You'll out-experiment and out-fail the competition by running high-velocity, rigorous experiments across every show, creator, piece of content, and commercial bet at Steven.com. You will build a team and a culture that treats deliberate failure as the primary learning mechanism. This role is deeply hands-on, involving setting hypotheses, isolating variables, checking statistical power, reading results, and moving to the next test.

Responsibilities

  • Own and drive the experimentation agenda across every show, creator, and IP property.
  • Lead hypothesis formation for every experiment with clear success, failure, and inconclusive criteria defined in advance.
  • Enforce single-variable discipline across all experiments.
  • Ensure every experiment is adequately powered before launch, including sample size calculations and defined measurement windows.
  • Systematically increase experimentation velocity and build the intake process for high-volume testing.
  • Build institutional memory by creating a searchable, structured record of every experiment run, its learnings, and decisions.
  • Partner with the VP of Engineering & Applied AI to apply AI tooling to experiment design, analysis, and reporting.
  • Ensure infrastructure supports testing at high velocity.

Requirements

  • Deep, first-principles command of experimentation mathematics: statistical significance, power, sample size calculation, p-values, confidence intervals, Type I/II errors, and the difference between statistical and practical significance.
  • Genuine mastery of the scientific method applied to product and content: hypothesis formation, single-variable isolation, measurement design, and result interpretation.
  • A track record of building experimentation culture, not just running tests.
  • Comfortable querying data and working shoulder-to-shoulder with engineers and data scientists at implementation depth.
  • Strong written and verbal communication skills.
  • Experience operating at pace in high-volume testing environments where speed of learning is the competitive edge.
  • Demonstrable experience leading product or content experimentation programs at a technology, media, or creator-economy company.
  • Owning the methodology, volume, and culture of experimentation programs.
  • Experience with algorithmic platforms and designing experiments against platform-specific metrics.
  • Experience in podcasting, video, social, or creator-economy.
  • Familiarity with YouTube/Spotify/social analytics (CTR, retention, watch time, audience behaviour).
  • Experience building an experimentation platform from scratch.
  • Familiarity with causal inference beyond standard A/B testing (holdouts, quasi-experiments, diff-in-diff).
  • Experience experimenting on AI/ML systems or prompt variations in production.
  • A background in statistics, maths, CS, economics, or a natural science.
  • Exposure to early-stage environments where you had to build the experimentation infrastructure yourself.
