• Contributes to the development of a unified and scalable science framework by connecting and consolidating existing science capabilities.
• Apply and expand causal machine learning and econometric methodologies, including CATE, difference-in-differences (DiD), matching techniques, panel methods, and heterogeneous treatment effect modeling.
• Support experimentation, measurement, and personalization initiatives through advanced statistical and machine learning approaches.
• Build, maintain, and optimize production machine learning and experimentation pipelines.
• Utilize MLOps and software engineering practices, including CI/CD, version control, testing, workflow management, monitoring, and documentation.
• Research and evaluate emerging AI and machine learning technologies to identify opportunities for innovation and adoption.
• Serve as a technical leader and subject matter expert by providing guidance and informal mentorship to team members.
• Communicate complex technical concepts, methodologies, and findings effectively to both technical and non-technical audiences, including leadership and business stakeholders.

Education Requirements

• Bachelor's or master's degree in Statistics, Data Science, Computer Science, Applied Mathematics, Economics, or a related quantitative field.

Experience Requirements

• 3+ years of applied data science experience with progressive responsibility and increasing technical complexity.
• Hands-on experience developing and implementing Generative AI applications.
• Experience contributing to production-quality machine learning systems using software engineering best practices.
• Experience partnering with product managers and stakeholders to translate business requirements into data science solutions and strategic priorities.
• Experience working with Azure, Databricks, or comparable cloud-based data science platforms.

Required Skills

• Strong proficiency in Python, SQL, and Git.
• Hands-on experience with one or more Generative AI technologies, including LLM fine-tuning, prompt engineering, retrieval-augmented generation (RAG), or agentic workflow development.
• Familiarity with causal machine learning and causal inference methodologies, including CATE, heterogeneous treatment effect modeling, difference-in-differences (DiD), matching techniques, and related approaches.
• Experience developing scalable machine learning solutions from research through production deployment.
• Knowledge of cloud-based data science platforms such as Azure and Databricks.
• Understanding software engineering best practices for machine learning applications.
• Ability to translate business challenges into analytical and scientific solutions.
• Strong verbal and written communication skills with the ability to communicate effectively across technical and business audiences.
• Ability to work effectively in ambiguous and evolving environments while contributing to early-stage strategy and vision.
• Strong analytical, problem-solving, and critical-thinking capabilities.

Preferred Skills

• Experience with MLOps practices, including workflow orchestration, model monitoring, reproducibility, deployment, and operationalization.
• Experience in retail, consumer products, media, marketplace analytics, or related industries.
• Familiarity with experimentation frameworks and measurement pipelines.
• Demonstrated ability to mentor, coach, or guide peers on technical best practices.
• Experience supporting personalization, loyalty, experimentation, or measurement-focused initiatives.
