Hire Talent
A Senior Snowflake Developer is a highly skilled professional responsible for designing, implementing, and optimizing data solutions using the Snowflake cloud data platform. This role plays a pivotal part in architecting data warehouses, data lakes, and ETL processes to enable efficient data storage, processing, and analytics for the organization.
Responsibilities
Data Architecture - Collaborate with data architects to design and develop Snowflake data models and schemas. - Create and maintain a well-structured data warehouse and data lake architecture. Data Integration - Develop ETL (Extract, Transform, Load) processes to ingest data from various sources into Snowflake. - Ensure data integration processes are efficient, reliable, and scalable. - Design and implement data pipelines using Snowflake features like tasks and streams. Performance Optimization - Optimize query performance by creating and maintaining appropriate indexes, materialized views, and clustering keys. - Identify and resolve performance bottlenecks in data processing. SQL Development - Write complex SQL queries, stored procedures, and user-defined functions (UDFs) to support data analytics and reporting needs. - Ensure SQL code follows best practices for readability and performance. Security and Access Control - Implement and manage security measures, including role-based access control (RBAC) and data encryption, to protect sensitive data. - Audit and monitor data access and user activities. Data Quality Assurance - Define and implement data quality checks and validation processes to maintain data accuracy. - Establish data quality rules and alerts to proactively identify issues. Documentation - Create and maintain technical documentation for data models, ETL processes, and data dictionaries. - Document best practices, standards, and guidelines for Snowflake development. Version Control and Deployment - Use version control systems (e.g., Git) for managing Snowflake SQL scripts and objects. - Coordinate the deployment of changes to Snowflake environments. Monitoring and Alerts - Set up monitoring and alerting for Snowflake environments to proactively detect and respond to issues. - Troubleshoot and resolve incidents related to data processing and performance. Backup and Recovery - Implement backup and recovery strategies to ensure data integrity and availability. - Develop and test data recovery procedures. Collaboration - Collaborate with data engineers, data scientists, and business analysts to understand data requirements and provide data solutions. - Work with cross-functional teams to support data-related projects and initiatives. Qualifications
- Bachelor's or master's degree in computer science, data engineering, or a related field. - 7+ years of experience as a Snowflake developer or data engineer with a focus on data warehousing and ETL. - Snowflake certification(s) is a plus. - Strong SQL skills and proficiency in data modeling and database design. - Knowledge of cloud data warehousing concepts and best practices. - Familiarity with data integration tools and technologies. - Solid understanding of data governance, data security, and compliance requirements. - Experience with version control systems and deployment processes. - Excellent problem-solving and troubleshooting skills.
