• Design, implement, and maintain advanced ML models, including regression, clustering, anomaly detection, and NLP applications.
• Write optimized SQL queries to extract, manipulate, and analyze large datasets.
• Translate complex data insights into actionable recommendations for technical and non-technical stakeholders.
• Collaborate with cross-functional teams to define data requirements and implement scalable analytical solutions.
• Monitor model performance, conduct A/B tests, and implement improvements to maintain accuracy and reliability.
• Document methodologies, workflows, and data dictionaries to ensure reproducibility and knowledge sharing.
• Mentor and guide junior data scientists, promoting best practices and technical excellence.

• Bachelor’s or Master’s degree in Data Science, Computer Science, Statistics, Mathematics, Engineering, or related field.
• Minimum 4-5 years of experience in data science, analytics, or ML roles, including production-level model deployment.
• Expertise in at least two areas of data science, managing projects end-to-end from technical implementation to stakeholder delivery.
• Strong proficiency in Python or R for data manipulation, ML modeling, and NLP.
• Expert-level SQL skills for large-scale data querying and analysis.
• Experience with regression, clustering, anomaly detection, NLP, and conducting experiments/A-B tests.
• Skilled in ML frameworks (scikit-learn, TensorFlow, PyTorch) and visualization tools (Tableau, Power BI, matplotlib, seaborn).
