Description
Senior Data Engineer; Must Have: Strong hands-on AWS, Snowflake, SQL and dbt experience. Nice to have – Python, PySpark, Airflow, Informatica
Requirements and Responsibilities
What You’ll Do
Design, develop, and maintain scalable data pipelines and data transformation frameworks using AWS, Snowflake, and dbt.
Develop robust ETL/ELT pipelines to ingest, transform, and integrate data from multiple source systems into Snowflake.
Build and maintain data models in Snowflake supporting analytics, reporting, operational applications, and downstream data consumers.
Develop reusable dbt models, macros, tests, snapshots, and incremental pipelines following established data engineering standards.
Write complex and optimized SQL for data transformation, aggregation, validation, and analytical workloads.
Design and implement scalable data ingestion solutions using AWS services such as S3, Glue, Lambda, and related data services.
Develop data pipelines for both structured and semi-structured data and work with formats such as JSON, CSV, Parquet, and Avro.
Implement incremental loading, CDC, partitioning, clustering, and other optimization techniques to efficiently process large datasets.
Design and maintain appropriate data warehouse schemas and dimensional models, including fact tables, dimension tables, star schemas, and data marts.
Implement data quality and validation frameworks using dbt tests, SQL-based validation, reconciliation, and data profiling.
Monitor data pipelines and proactively identify failures, performance issues, data quality problems, and processing bottlenecks.
Troubleshoot pipeline failures and data discrepancies and perform detailed root-cause analysis.
Optimize Snowflake workloads through appropriate warehouse sizing, query optimization, clustering, partition pruning, and workload management.
Implement appropriate logging, monitoring, error handling, alerting, and recovery mechanisms for production data pipelines.
Develop automated data pipelines and workflows using orchestration tools such as AWS Glue, Airflow, or similar technologies.
Implement version control, CI/CD, and deployment processes for dbt models, SQL code, and data pipelines.
Work closely with Data Architects, Business Analysts, ETL Developers, SQL Developers, QA Engineers, and application teams to understand requirements and deliver scalable data solutions.
Participate in data architecture and technical design discussions and contribute to data platform modernization initiatives.
Support migration of legacy ETL processes to cloud-based AWS/Snowflake ELT architectures.
Develop and maintain technical documentation covering data pipelines, data models, source-to-target mappings, dependencies, and operational procedures.
Conduct code reviews and ensure adherence to development, security, performance, and data engineering standards.
Support production releases, incident management, troubleshooting, and post-production validation.
Work in an Agile/Scrum environment and actively participate in sprint planning, daily stand-ups, reviews, retrospectives, and technical discussions.
Mentor junior data engineers and contribute to knowledge sharing and continuous improvement.

This page is for Indian job seekers preparing for cloud engineer, DevOps, backend and solutions architect roles that list AWS as a skill, whether you are a fresher with a first certification or an experienced engineer moving into a senior role. It covers 60 questions in three levels: core services and concepts, then design and configuration choices for one to three years of experience, and finally scenario, security, cost and troubleshooting questions asked in senior rounds. Read each answer, explain it aloud in your own words, and try the CLI commands in a practice account with a billing alert set.
Questions you may be asked
What is the difference between an AWS Region and an Availability Zone?
Explain the AWS shared responsibility model.
What is Amazon EC2, and how do you read an instance type name like m7g.large?
What is Amazon S3, and what are its main storage classes?
