Data Scientist 5 - Infrastructure Experimentation

Netflix Netflix · Big Tech · United States · Remote · Data & Insights

Netflix is seeking a Senior Data Scientist for Infrastructure Experimentation to build and maintain ML models that predict the infrastructure cost impact of A/B experiments. This role involves partnering with engineering teams to measure, model, and surface infrastructure impact, enabling more holistic decisions that balance member impact with infrastructure performance. The ideal candidate has experience in experimentation, causal inference, and applied ML within the infrastructure domain.

What you'd actually do

  1. Build and maintain machine learning models that predict the infrastructure cost impact of A/B experiments, translating experimentally observed signals (e.g., request volume changes) into business and system metrics (e.g. projected annualized costs)
  2. Drive adoption of infrastructure metrics within the experimentation community through analysis, consultation with experiment owners, documentation, and training
  3. Partner with platform teams (Observability, Experimentation Platform) to improve the quality and coverage of infrastructure usage data feeding our models
  4. Extend our measurement framework to new metrics (e.g., latency) and new experiment types (e.g., infrastructure canary tests)
  5. Champion an infrastructure lens within the broader experimentation community, helping shift culture toward reasoning about the full ROI and infrastructure impact of experiments
