• Present results and insights to business stakeholders in a clear and impactful manner, driving actionable recommendations.
• Continuously research and evaluate new tools, technologies, and methodologies to improve the team's capabilities and outcomes.
  

Required Skills & Qualifications:

• Bachelor's or Master's degree in Computer Science, Data Science, Statistics, Applied Mathematics, or a related field.
• 4-9 years of hands-on experience in data science, machine learning, and Python for data science applications.
• Strong proficiency in Python and its data science stack — Pandas, NumPy, Scikit-learn, Matplotlib, Seaborn, etc.
• Solid understanding of machine learning algorithms including supervised, unsupervised, and ensemble methods.
• Experience building and deploying ML models in production environments.
• Good knowledge of data wrangling, feature engineering, model tuning, and evaluation techniques.
• Familiarity with version control systems (e.g., Git), cloud platforms (e.g., AWS, GCP, or Azure), and ML Ops best practices is a plus.
• Excellent problem-solving skills and ability to break down complex problems into actionable solutions.
• Strong communication and collaboration skills, with the ability to lead technical discussions and influence stakeholders.
  

Preferred Skills:

• Experience with deep learning frameworks such as TensorFlow or PyTorch.
• Familiarity with distributed data processing (e.g., Spark or Dask).
• Exposure to business intelligence tools and data visualization platforms like Power BI or Tableau
