About the Job

Requirements

  • A Bachelor's or Master's degree in Data Science, Statistics, Economics, Artificial Intelligence and Machine Learning, Computer Science, Business Analytics, or another quantitative field.
  • At least 10 years of experience in Data Science or Analytics, including at least 3 years leading data science teams and mentoring data scientists, with measurable business impact through predictive modelling and causal inference or experimentation; commercial or marketing analytics experience is preferred.
  • Hands-on expertise in predictive modelling, including classification on skewed data with imbalance handling such as SMOTE and class weighting; ensemble and tree-based models such as LightGBM, XGBoost, and CatBoost; linear models; anomaly detection; unsupervised methods such as clustering and segmentation; and time-series forecasting such as ARIMA and Prophet.
  • Rigorous model validation and explainability skills, including SHAP, precision-recall methods, and calibration methods for imbalanced problems.
  • Deep expertise in causal inference and experimentation, including experimental design, A/B testing, quasi-experimental methods, and econometrics.
  • Hands-on experience building Marketing Mix Models and multi-touch attribution models using regression-based, time-decay, Markov-chain, and Shapley-value methods, and frameworks such as Google Meridian, PyMC-Marketing, Meta Robyn, LightweightMMM, Orbit, PyMC, or Stan. This includes model diagnostics such as convergence, priors, and posterior predictive checks, and turning outputs into budget optimization, response curves, and scenario simulations.
  • Expert proficiency in Python and SQL, with strong experience in Spark for distributed computing, Airflow, Git, AWS, and Tableau or an equivalent tool for visualization and storytelling.
  • Exposure to and recent experience with GenAI tools and large language models such as OpenAI, Claude, Gemini, and DeepSeek; coding assistants such as GitHub Copilot; and building AI agents using frameworks such as LangChain, LangGraph, AutoGen, or CrewAI.

Responsibilities

  • Lead the Predictive AI & Optimization and Causal AI & Experimentation data science sub-streams supporting commercial teams, owning their technical direction and delivery.
  • Work directly with product owners to translate business questions into predictive, causal, and optimization solutions.
  • Lead, mentor, and develop Senior Data Scientists and Data Scientists across both sub-streams; build technical depth, modular coding standards, and agile delivery habits.
  • Lead the design, calibration, and validation of Bayesian and frequentist Marketing Mix Models that account for adstock, saturation, seasonality, and hierarchical or geo-level effects.
  • Oversee multi-touch attribution and brand performance analytics, translating results into practical recommendations on channel mix and spend.
  • Design and govern experiments, including A/B tests, quasi-experimental designs such as difference-in-differences and synthetic control, and econometric analysis, to measure the true impact of commercial initiatives.
  • Oversee the design and delivery of predictive models for commercial use cases, including classification on highly imbalanced data, anomaly detection, segmentation, and time-series forecasting.
  • Turn predictions into decisions through optimization, including budget and resource allocation, response curves, return on investment and marginal return on investment analysis, and scenario-planning simulations.
  • Rapidly design and build proofs of concept, prototypes, and business case studies, including generative AI and agent-based solutions where they add value, to demonstrate tangible impact.
  • Set methodological standards for each sub-stream, choosing suitable approaches for problems and explaining why alternatives are unsuitable.
  • Review model designs, validation results, and critical code, and resolve technical blockers quickly.
  • Present findings and trade-offs clearly to technical and non-technical audiences so complex model results support confident decisions.
  • Work with global cross-functional teams in an agile environment, including demos, reviews, and retrospectives, to improve deliverables.
  • Ensure reproducibility, documentation, and peer review across all delivered models.

Desired Qualifications

  • Recognized professional certifications in Data Science, Machine Learning, Cloud AI Platforms, or Advanced Analytics are advantageous.
  • Experience in commercial or marketing analytics is preferred.

About the Company

Roche

Global pharmaceuticals and diagnostics company

Roche is a global leader in pharmaceuticals and diagnostics. It develops medicines and diagnostic tools that help detect, monitor, and treat diseases, using research and biotechnology to drive new therapies and tests. Roche combines drug development with in-house diagnostic products to support personalized medicine, where treatments are tailored to individual patients based on test results. Its approach differs from many peers by integrating drug discovery with diagnostic capabilities and by expanding its research through strategic acquisitions (like Genentech) to strengthen its biotechnology and R&D capabilities. The company’s goal is to improve patient outcomes and healthcare worldwide by delivering reliable medicines, accurate diagnostic tests, and data-driven care.
