Job Description:

We are looking for aSenior Data Engineerwith strong hands-on expertise inPython, PySpark, Snowflake, dbt, Apache Iceberg, and AWSto design, develop, and maintain scalable enterprise data solutions.

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 scalableETL/ELT data pipelines.
• Develop production-quality data-processing solutions usingPython 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 usingSnowflake.
• 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 usingdbt.
• 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 usingApache 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 onAWS.
• Build data-processing workloads leveraging services such asS3, Glue, EMR and Lambdawhere 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 optimizeSpark/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.
