This is a highly strategic and execution-oriented role focused on identifying, prioritizing, launching, and scaling experiments that directly impact conversion, retention, and lifetime value.Reporting to the Principal Machine Learning Engineer for Sign-Up Optimization, you will act as the connective tissue between product, ML, engineering, data science, design, and growth ensuring we are running the right experiments, running them well, and learning from them rigorously. This role blends product thinking, scientific rigor, experimentation design, and operational management. What Youll Do Experimentation Strategy & Roadmapping * Define and own the experimentation roadmap across sign-up, onboarding, andcancellation flows for Paramount+ and Pluto TV. * Identify high-impact test opportunities across UX, messaging, offers,personalization, pricing, bundling, and model-driven experiences. * Translate business goals (conversion, churn reduction, engagement, LTV) intostructured, testable hypotheses. * Prioritize experiments using data-driven frameworks balancing impact, risk, andresource constraints. End-to-End Experiment Ownership * Drive experiments from ideation design instrumentation launch feedback iteration. * Partner with ML engineers and applied scientists to test model-driven experiences(ranking, personalization, content ordering, offer targeting). * Ensure experiment configurations are correctly implemented and debug issues intargeting, logging, or exposure. * Monitor live experiments for integrity, guardrail breaches, or unintended sideeffects. * Lead post-test readouts and translate results into clear, actionable next steps. Scientific Rigor & Measurement * Design robust A/B, multivariate, and sequential testing frameworks. * Define primary metrics, guardrails, and success criteria aligned to long-term value,not just short-term conversion. * Improve offline-to-online validation practices in partnership with ML teams. * Standardize experimentation best practices across the Applied Intelligence group. * Champion causal reasoning and statistical discipline in decision-making. Cross-Functional Management * Partner closely with Product, Growth, Marketing, Design, Data Science, Analytics, and Engineering. * Serve as the central point of coordination for experimentation across the lifecycleentry/exit flows. * Communicate insights clearly to both technical and executive audiences. * Create scalable documentation and experiment tracking processes., * Impact: Your work will directly shape how millions of users begin and end their relationship with Paramounts streaming products. * Ownership: You will define the experimentation engine for some of our most critical user journeys. * Influence: Work alongside senior ML leaders and help establish how personalization and growth intersect across the company. * Scale: Paramount is investing heavily in foundational AI and experimentation infrastructure this is an opportunity to build systems that operate at global streaming scale.
