Requirements: Master’s degree in Statistics, Data Science, Computer Science, Economics, Mathematics, Engineering, or a related quantitative discipline is required. PhD in Statistics, Data Science, or a related quantitative field is strongly preferred. At least eight years of progressive experience in data science, analytics, or machine learning, including substantial hands-on work with large-scale data environments. Demonstrated success leading or contributing as a senior technical expert to experimentation, measurement, and advanced analytics initiatives. Deep expertise in marketing experimentation, including experimental design, A/B and multivariate testing, metric development, lift measurement, and incrementality analysis. Strong knowledge of causal inference, hypothesis testing, statistical modeling, and statistical power analysis. Hands-on experience developing and deploying market mix models (MMM), attribution models, and uplift models. Advanced programming skills in Python, Spark/PySpark, and SQL. Practical experience developing and deploying machine learning models using techniques such as clustering, classification, regression, neural networks, anomaly detection, recommendation engines, and predictive modeling. Experience with large language models (LLMs), Generative AI solutions, and emerging agent-based frameworks such as LangChain, LangSmith, or comparable technologies. Familiarity with modern cloud-based data platforms, including Databricks, Snowflake, or similar data lake environments. Experience building and deploying analytical solutions in AWS and Azure cloud environments. Familiarity with containerization and development tools such as Kubernetes, Docker, and Git. Experience with data visualization and business intelligence tools; Tableau is preferred. Familiarity with data science platforms such as Dataiku is an advantage. Experience working in financial services or another highly regulated, data-intensive industry is preferred. Proven ability to influence senior stakeholders, collaborate across business functions, and translate complex challenges into scalable analytical solutions with measurable impact. Strong leadership, mentoring, communication, and storytelling skills, including the ability to present technical findings as clear, executive-level recommendations. Ability to navigate ambiguity, prioritize competing demands, manage multiple initiatives, and deliver results in a fast-paced environment. Relevant certifications in data science, machine learning, or cloud technologies are a plus. Benefits: Annual salary range: $170,000–$200,000. Eligibility for an annual bonus incentive program. Workplace flexibility and a collaborative working environment. Opportunities to shape advanced analytics strategy and influence high-impact business decisions. Professional growth through exposure to emerging AI technologies, experimentation methodologies, and large-scale data science initiatives. Opportunities to mentor colleagues, establish best practices, and contribute to a culture of innovation and continuous learning. Commitment to diversity, inclusion, and equal employment opportunity.
