Staff Product Manager, Experimentation

About the Role

This role will lead the future of experimentation across WBD’s streaming ecosystem. It involves defining the long-term strategy for experimentation, owning the roadmap for the experimentation platform, and partnering with leaders across product, engineering, and data science to unlock high-quality decision‑making at scale. The role enables hundreds of product managers and engineers to experiment with minimal friction, interpret results with confidence, and optimise product experiences reaching tens of millions of viewers. As a senior individual contributor, it shapes company‑wide mechanisms, raises the bar for experimentation quality, mentors PMs, and serves as the go‑to expert when tests yield ambiguous or conflicting outcomes. The position sits within the Labs organisation, the experimentation engine behind WBD’s streaming products. Key Responsibilities

Develop and articulate a multi-year strategy for experimentation, optimisation, and insights across WBD’s streaming portfolio. Own the roadmap for the experimentation platform, prioritising foundational features such as experiment setup workflows, guardrail metrics, automated analytics, and multivariate testing. Drive platform enhancements that reduce friction, increase experiment reliability, and scale with product complexity. Expand experimentation coverage across new product surfaces, customer journeys, international markets, and emerging experience areas. Establish and evolve company‑wide standards for A/B testing methodology, analysis, and communication, and define mechanisms such as review forums, playbooks, and quality gates to ensure experimentation rigour. Provide thought leadership and hands‑on guidance when experiments yield ambiguous, contradictory, or hard‑to‑interpret results Partner with teams to design high‑quality tests, ensure strong measurement practices, and support teams facing challenges in experiment execution, evaluation, or integration with platform services. Define how experimentation integrates with broader product, data, and platform roadmaps, and build tooling that empowers teams to run, interpret, and act on experiments independently. Partner with data science to improve automated analysis pipelines, metric consistency, and test validity. Influence senior leaders and partner teams across engineering, product, analytics, design, and marketing on using experimentation to prioritise initiatives and investment opportunities, and drive alignment on experimentation strategy, frameworks, and KPI definitions. Mentor PMs and engineers, raising the maturity of experimentation and product thinking across WBD. Required Experience & Qualifications

8+ years of product management experience, with significant ownership of experimentation, optimisation, or data‑driven decision‑making platforms.
