• Perform feature engineering, dataset preparation, and model optimization to improve predictive accuracy and operational performance. 

• Evaluate models using appropriate statistical methods and performance metrics, documenting findings and informing iterative improvements. 

• Work with Data Engineers to understand and enhance data pipelines, ensuring model-ready datasets are accurate, complete, and consistent. 

• Collaborate with AI Developers and LLMOps/MLOps Engineers to integrate ML models into production environments or decision-support applications. 

• Build visualizations, dashboards, data stories, and executive-friendly summaries to communicate insights clearly to stakeholders. 

• Support human-centered design processes by translating user needs into modeling requirements and refining model outputs based on feedback. 

• Contribute to reproducibility and auditability by maintaining well-organized code, notebooks, documentation, and experiment histories.

• Proficiency in Python and core data science libraries (Pandas, NumPy, scikit-learn, Matplotlib/Seaborn). 

• Hands-on experience with at least one modern ML framework (e.g., PyTorch, TensorFlow, XGBoost). 

• Experience writing efficient SQL queries and working with structured or semi-structured data in cloud or database environments. 

• Familiarity with cloud data and ML platforms such as AWS, Azure, GCP, or Databricks. 

• Strong understanding of statistics, probability, experimental design, and model validation techniques. 

• Ability to communicate technical concepts clearly to stakeholders and collaborate across multidisciplinary teams. 

• Experience with dashboarding tools (Tableau, Power BI) or Python visualization libraries is a plus. 

• Curiosity and adaptability, with a drive to stay current in rapidly evolving data and ML practices.
