- Develop and maintain data models, data marts, and analytical datasets. 

- Collaborate with cross-functional teams to gather requirements and deliver data-driven solutions. 

- Perform exploratory data analysis (EDA) and create machine learning models as required. 

- Implement data quality checks, validation rules, and monitoring processes. 

- Automate data workflows and ensure timely availability of data. 

- Work with cloud platforms such as Azure, AWS, or GCP for data engineering activities. 

Technical Skills 

- Proficient in programming languages such as Python or R 

- Expertise in statistics, machine learning algorithms, and data mining techniques 

- Experience with data preprocessing, feature engineering, and model validation 

- Skilled in data visualization tools and libraries (Tableau, Power BI, Matplotlib, Seaborn) 

- Familiarity with big data platforms (Spark, Hadoop) and SQL databases 

- Knowledge of cloud-based ML platforms (AWS SageMaker, Azure ML, GCP AI Platform) 

- Understanding of experimental design and A/B Testing 

- Ability to communicate complex technical concepts to non-technical stakeholders 

Key Responsibilities (non-exhaustive) 

- Analyze large and diverse datasets to identify trends, patterns, and insights 

- Develop, train, and validate predictive and classification models 

- Analyze and select the appropriate AI foundation models for use where appropriate 

- Design experiments and conduct hypothesis testing to support business initiatives 

- Collaborate with data engineers to prepare and optimize data for analysis 

- Translate analytical findings into clear, actionable recommendations 

- Present insights and reports to stakeholders using visual storytelling techniques 

- Monitor and maintain models in production environments to ensure ongoing accuracy 

- Stay updated on emerging tools, techniques, and best practices in data science 

Quality Testing Responsibilities 

- Develop and execute data validation and data quality test cases. 

- Perform unit and integration testing for data pipelines. 

- Monitor data accuracy, completeness, and consistency across systems. 

- Identify data anomalies and work with engineering teams to resolve issues. 

- Document test results and maintain testing logs. 

Preferred Qualifications 

- Bachelor’s or Master’s degree in Computer Science, Data Science, Engineering, or related field. 

- 3–5 years of experience in data engineering, data science, or related domains. 

- Hands-on experience with SQL, Python, and distributed data systems. 

- Knowledge of machine learning techniques and statistical analysis. 

- Experience with cloud data platforms (Azure Data Factory, AWS Glue, GCP BigQuery). 

- Familiarity with DevOps practices and CI/CD for data pipelines. 

Platforms & Operations Experience (Preferred) 

- Experience working with Azure, AWS, or Google Cloud data tools. 

- Operational experience with data orchestration tools (Airflow, ADF, Glue). 

- Understanding of Kubernetes, Docker, or containerized environments. 

- Hands-on experience with data warehousing platforms (Snowflake, Redshift, BigQuery). 

- Experience in monitoring, logging, and alerting operations for data workflows.
