Strategy & Analytics Experimentation Director

Join Faire as the Experimentation Director, where you will be the authority on experimentation and drive the rigor of experimentation across the company. You will own the experimentation methodology and principles, build and maintain Faire's experimentation operating system, and partner with various teams to design and measure experiments. This high-impact role requires extensive experimentation experience, deep statistical expertise, and strong cross-functional influence.

• Assurer la rigueur de l'expérimentation chez Faire, en possédant la méthodologie et les principes d'expérimentation.
• Construire et maintenir le système d'expérimentation de Faire, y compris les processus de révision des expériences et le suivi des expériences à l'échelle de l'entreprise.
• Agir en tant qu'expert de Faire en matière d'inférence causale dans les cas où un véritable essai ne peut pas être réalisé.
• You understand data and experimentation platforms — how assignment infrastructure, metric pipelines, and data models work, and how methodological choices interact with them
• You have strong cross-functional influence. You can raise the bar on how teams across Engineering, Product, Data Science, and Strategy & Analytics design, run, and interpret experiments
• You have extensive experimentation experience. You have designed, reviewed, and analyzed hundreds of experiments — ideally on a central experimentation or platform team at a company with a mature testing culture
• You have deep statistical expertise. You have a strong command of the methods that make experiments trustworthy: power and sample sizing, sequential testing, variance reduction, multiple comparisons, and interference between units. When a clean A/B test isn't possible, you can design and run alternatives
• You are practical. You balance rigor with speed and optimize for impact
• You are analytically rigorous. You read results skeptically and catch subtle problems others miss
• You are a strong communicator. You make our experiments and their impact legible to others at Faire through strong spoken and written communication
• 10+ years of relevant experience in experimentation, data science, or a closely related analytical role
