The Manager, Experimentation leads NBCU’s incrementality testing program for Performance and Device media in partnership with the Sr. Manager of Media Experimentation. The ideal candidate is the methods & QA owner: you will shape the learning agenda, enforce power standards, ensure study designs are decision-grade, and translate vendor results into clear budget guidance—reconciled with Marketing Mix Modeling (MMM) and Multi-Touch Attribution (MTA) so leaders can act with confidence and speed.

• Collaborate with Sr. Manager of Media Experimentation on ensuring clear schedules, accurate data inputs, agency and/or vendor alignment, and structured documentation of results 
• Partner with the vendor and a Media Analytics analyst to produce clear, defensible readouts that inform decisions (lift, uncertainty, risks); write concise decision memos and hand off to Optimization and & Insights team for execution and pacing/optimization.  
• Drive calibration with MMM/MTA; propose tiebreakers and thresholds for decisioning; contribute to cross-channel measurement efforts by triangulating learnings.  
• Ensure high quality of analysis with speed; Monitor design defects/leakage; run targeted validations (SQL/R/Python spot checks) as needed; improve run-rate without sacrificing validity. 
• Mentor a Media Analytics analyst; uplevel partner teams (brief quality, power, common pitfalls); collaborate with data science and other analytics & media teams; contribute to a standardized measurement approach across the NBCU Media Group.  

• 4+ years in marketing/media experimentation with direct design/QA ownership and experience partnering with an incrementality testing measurement vendor (e.g., Haus, Measured, or similar).  
• Proven command of causal inference in media—appropriate use of RCT, geo, diff-in-diff, and platform holdouts—and the ability to evaluate vendor assumptions/methods.  
• Familiarity with power analysis, and failure modes (leakage, seasonality, parallel trends); history of stopping or redesigning under-powered tests.  
• Platform experience: Google/Meta/TikTok incrementality and at least one CTV/Device environment (e.g., Roku, Samsung, Vizio).  
• Experience reconciling vendor experiment reads with MMM/MTA and informing planning/pacing decisions without surprises.  
• Fluent in SQL and Excel
