Data ScientistData

As a Senior Data Scientist, you will develop advanced AI and machine learning solutions that optimize product portfolios and drive data-informed business decisions. You will work on high-impact challenges spanning recommendations, personalization, forecasting, segmentation, and commercial optimization. Collaborating with multidisciplinary teams, you will transform complex datasets into scalable, production-ready solutions that deliver measurable business value. You will help shape machine learning strategies, champion innovative techniques, and establish best practices across the data science lifecycle. The role combines hands-on technical expertise with architectural guidance, experimentation, and continuous improvement. You will also mentor fellow data scientists and partner with engineering, product, and business stakeholders in a collaborative, agile, and globally connected environment.

Design, develop, and deploy advanced machine learning and deep learning models for portfolio optimization, recommendations, personalization, promotions, segmentation, data imputation, and insight discovery.

Analyze complex datasets to uncover business opportunities, generate actionable insights, and support strategic decision-making through robust statistical modeling and predictive analytics.

Drive innovation by evaluating and adopting emerging machine learning techniques, advanced algorithms, and AI-driven approaches to solve complex business challenges.

Architect, develop, and optimize large-scale data processing workflows using cloud technologies and distributed computing platforms, including Azure, Databricks, Spark, and PySpark.

Build and maintain reliable, scalable data pipelines and modeling workflows using Python and PySpark, incorporating automation and reusable components to improve efficiency and reduce operational overhead.

Ensure models are production-ready, balancing predictive accuracy, stability, explainability, scalability, and real-world business constraints.

Establish and promote best practices for experimentation, model validation, performance evaluation, version control, CI/CD, and reproducible machine learning workflows.

Collaborate closely with data engineers, product managers, and business stakeholders to translate business objectives into technical requirements and deliver end-to-end data science solutions.

Mentor junior and mid-level data scientists, share technical knowledge, and contribute to a culture of experimentation, technical excellence, and continuous learning.
