·      Implement and support Snowflake Tasks, Streams, stored procedures, and scheduled workflows; perform unit, integration, and validation testing prior to production release.

·      Participate in schema and object deployments using Git-based version control; maintain source control, versioning, and change documentation for all Snowflake database objects.

·      Implement and maintain Snowflake security configurations including RBAC, object permissions, row-level security, and masking policies; support audit and compliance activities.

·      Generate and maintain Snowflake consumption and usage reports; identify opportunities to improve warehouse utilization, storage efficiency, and query performance.

·      Collaborate with BI teams to optimize datasets for Power BI, Qlik, and other analytical tools; coordinate with Platform Administrators on environment setup, migrations, and operational readiness.

·      Work with Data Governance teams to apply and validate data quality standards, data classifications, and masking policies within Snowflake.

Requirements

Required Skills & Experience:

·      Snowflake SQL: 5+ years of advanced SQL development, including complex query optimisation, data modelling, performance tuning, and ETL/ELT development within Snowflake environments.

·      Snowflake Administration: 3+ years of hands-on experience administering Snowflake platforms, including RBAC, warehouse management, monitoring, performance optimization, and cost governance.

·      dbt (Data Build Tool): 4+ years designing, developing, and maintaining scalable data transformation frameworks using dbt, including testing, documentation, and CI/CD integration.

·      Git / Version Control: 5+ years using Git-based source control systems (GitHub, GitLab, or Bitbucket) for collaborative development, branching strategies, code reviews, and release management.

·      CI/CD Pipelines & Deployment Automation: 5+ years implementing and supporting CI/CD pipelines for data warehouse and analytics deployments using Azure DevOps, GitHub Actions, GitLab CI/CD, or equivalent platforms.

·      Experience with Informatica IDMC.
