Expected Work Experience 4 to 7 Years
Job Location India
Job Summary We are seeking a Sr. Data Engineer / Sr. BI Developer - DA&A with 4-7 years of experience in designing and building scalable cloud-based data platforms using AWS, Python, AWS Glue, Apache Airflow, Amazon S3, Amazon Redshift, and AWS Step Functions. Candidate must have relevant experience of 4 to 7 Years. The ideal candidate should have hands-on expertise in developing robust ETL/ELT pipelines, orchestrating complex workflows, implementing data ingestion frameworks, and supporting enterprise data warehousing solutions. Experience with Python, PySpark, SQL, and cloud-native data processing is essential. The role involves building and optimizing data pipelines using AWS Glue, managing workflow orchestration through Airflow and Step Functions, designing data lake architectures on Amazon S3, and supporting analytics and reporting solutions on Amazon Redshift. The candidate should be proficient in data modeling, performance tuning, monitoring, troubleshooting, CI/CD practices, and automation. Exposure to modern data engineering tools such as Snowflake, Databricks, dbt, Terraform, or similar cloud technologies will be considered an added advantage.
