The Data Science team is seeking experienced Machine Learning Scientists to drive business-critical forecasting and pricing products, focusing on demand forecasting and e-book pricing optimization. Responsibilities Own end-to-end ML systems scoping, feature engineering, model development, backtesting/validation, deployment (with platform partners), monitoring/alerting, retraining cadence, and ongoing reliability improvements Create and maintain production-safe evaluation infrastructure automated backtests, error decomposition, uncertainty quantification, data validation, regression gates, and auditable model/version lineage Build AI-assisted/agentic development workflows (e.g., Claude Code) to automate repetitive tasks with human review and measurable quality gates Define success metrics tied to business outcomes; communicate assumptions, limitations, and risk so model outputs are used correctly by stakeholders Write production-quality, testable code and support reproducible workflows Partner across functions to translate business needs into a prioritized technical roadmap and measurable impact Build and improve forecasts across time horizons and business segments (demand, inventory, supply chain, resource allocation), selecting approaches that balance accuracy, stability, interpretability, and operational cost Productize forecast outputs for stakeholders clear definitions and assumptions, versioned releases, and reporting that explains what changed, why it changed, and how uncertainty should shape decisions Feature engineering, uncertainty quantification and calibration, hierarchical/segmented forecasting where appropriate Partner with operations, supply chain, inventory, finance, and marketing leaders Full technical ownership of our automated e-book pricing system, including model architecture (Bayesian hierarchical models), inference pipelines, and decision logic Design, run, and analyze backtests and live A/B tests to validate pricing strategies and measure real-world revenue impact Evaluate when to enhance the existing system versus migrate to new approaches; make and execute on architectural recommendations Balance revenue optimization with brand considerations and sales stability Collaborate with the print book pricing team, identifying transferable techniques and shared infrastructure Skills 5+ years in applied ML/data science, including owning models in production (deployment, monitoring, incident response, retraining) Strong forecasting expertise (time-series methods, feature engineering, rigorous backtesting) OR deep expertise in Bayesian statistical methods and probabilistic programming Strong statistics fundamentals; comfort with probabilistic forecasting and explaining uncertainty in practical terms Strong Python (or R) and SQL; writes production-quality, testable code Strong communication and cross-functional collaboration with non-technical stakeholders Experience using AI-assisted development workflows responsibly (verification loops, reproducibility, automated checks) 8+ years in applied ML/data science, or PhD with 3+ years of applied experience Experience building ML systems end-to-end (not just models) backtesting frameworks, scheduled retraining, monitoring/alerting, and automated reporting into planning or decision workflows Demonstrated ability to inherit complex systems built by others and make sound architectural decisions with high autonomy Technical leadership raises the bar on evaluation, reproducibility, and production practices; mentors less-senior team members Experience with Claude Code or agentic workflows is a plus, but we prioritize strong fundamentals and the ability to learn new workflows effectively Location Remote eligible (U.S.), but NYC area preferred Benefits Annual profit award or bonus, subject to company results Medical/Prescription drug insurance Dental Vision Health Care/Dependent Care Flexible Spending Account Health Savings Account Pre-Tax and Roth 401(k) Short and Long-Term Disability Insurance Life/AD&D Insurance Commuter Benefits Student Loan Repayment Program Educational Assistance Generous paid time off Company Overview Penguin Random House is a book publishing company that provides audiobooks, eBooks, and printing services.
