The candidate should have strong experience working with high-volume data processing, cloud-based data platforms, modern lakehouse architectures, ETL/ELT pipelines, data modeling, performance optimization, and production-grade engineering practices. The ideal candidate should be capable of independently owning complex data-engineering components, contributing to technical design and architecture decisions, troubleshooting production issues, and providing technical guidance to other engineers. Key Responsibilities: 1. Data Pipeline Engineering Design, develop, test, and maintain scalable ETL/ELT data pipelines . Develop production-quality data-processing solutions using Python and PySpark . Build reusable frameworks and components for ingestion, transformation, validation, and publishing of data. Process large structured, semi-structured, and distributed datasets. Implement incremental and batch-processing patterns where appropriate. 2. Snowflake Development Design and develop scalable data solutions using Snowflake . Develop complex SQL transformations, data models, views, and reusable data structures. Optimize Snowflake workloads for performance, scalability, and cost. Implement appropriate data-loading and transformation patterns between AWS data platforms and Snowflake. Troubleshoot performance and data-quality issues across Snowflake workloads. 3. dbt Development Build and maintain transformation pipelines using dbt . Develop modular, reusable, maintainable dbt models. Implement dbt tests and documentation. Follow appropriate development practices for source, staging, intermediate, and business-layer transformations. Support automated deployment and CI/CD practices for dbt projects. 4. Apache Iceberg / Lakehouse Design and implement data-lake and lakehouse solutions using Apache Iceberg . Build scalable table structures for large analytical datasets. Work with partitioning, schema evolution, incremental processing, and table-maintenance strategies. Integrate Iceberg-based datasets with Spark and AWS-based data-processing services. Ensure efficient storage and query patterns for high-volume datasets. 5. AWS Data Engineering Design and implement cloud-native data solutions on AWS . Build data-processing workloads leveraging services such as S3, Glue, EMR and Lambda where appropriate. Implement secure access patterns using AWS IAM. Monitor data workloads and troubleshoot operational issues. Participate in designing scalable, reliable, secure, and cost-efficient cloud data architectures. 6. Performance & Scalability Diagnose and optimize Spark/PySpark jobs , SQL queries, Snowflake workloads, and data pipelines. Identify bottlenecks involving compute, storage, partitioning, data skew, transformations, and queries. Design solutions capable of supporting increasing data volumes without unnecessary infrastructure cost. 7. Data Quality & Governance Implement automated data-quality checks across ingestion and transformation layers. Establish proper logging, monitoring, exception handling, and reconciliation mechanisms. Follow organizational standards for data security, governance, lineage, and access controls. Ensure production pipelines are reliable, auditable, and maintainable. 8. Engineering Best Practices Write clean, modular, reusable, testable, and maintainable code. Perform code reviews and enforce engineering standards. Implement unit, integration, and data-validation testing. Use Git-based version control and CI/CD practices. Create and maintain appropriate technical documentation. 9. Senior-Level Responsibilities Independently drive technically complex data-engineering requirements from design through production deployment. Participate in solution design and architecture discussions. Evaluate alternative implementation approaches and recommend appropriate solutions. Troubleshoot complex production and performance issues. Mentor junior and mid-level data engineers. Collaborate with Architects, Product Owners, Business Analysts, Data Scientists, QA, DevOps, and application teams. Translate business/data requirements into scalable technical solutions. Identify technical risks and proactively recommend improvements.
