Snowflake Migration Data Architect

Onsite in Burbank CA

9 Months Contract

Summary

Seeking a Senior level Data Analyst/Data Architect to support a critical enterprise data migration initiative, transitioning our data platform from Microsoft SQL Server to Snowflake. This resource will design scalable data architectures, build robust migration pipelines, and enable modern self-service analytics through Tableau and Power BI. The ideal candidate brings deep expertise in cloud data warehousing, ETL/ELT engineering, and business intelligence.

Responsibilities

Migration Architecture & Design

Lead end-to-end source-to-target mapping design for the SQL Server to Snowflake migration, including schema analysis, data profiling, and transformation logic documentation

Architect Snowflake environments including database/schema structures, virtual warehouses, role-based access control (RBAC), and resource monitors

Design and document data flow diagrams, lineage maps, and migration runbooks to ensure traceability and auditability throughout the migration lifecycle

Define standards for naming conventions, data types, partitioning strategies, clustering keys, and time-travel/fail-safe policies in Snowflake

ETL/ELT Development & Scripting

Write and optimize complex T-SQL scripts to extract and transform data from SQL Server sources for ingestion into Snowflake

Develop Snowflake SQL scripts, stored procedures, tasks, streams, and dynamic tables to implement transformation logic and incremental load patterns

Build and maintain ELT pipelines leveraging tools such as dbt, Azure Data Factory, Fivetran, or Informatica for automated data movement

Implement data validation and reconciliation scripts to verify source vs. target row counts, aggregates, and business rules post-migration

Tune query performance in Snowflake through execution plan analysis, clustering optimization, and materialized view strategies

Data Modeling & Governance

Design and maintain dimensional models (star/snowflake schemas), OBT structures, and data vault patterns appropriate for Snowflake's architecture

Collaborate with data stewards and business stakeholders to define data dictionaries, business glossaries, and metadata standards

Establish data quality frameworks and implement automated profiling, anomaly detection, and SLA monitoring

BI Reporting & Visualization

Design and develop Tableau dashboards and published data sources connected to Snowflake, optimizing live and extract connections for performance

Build Power BI datasets, reports, and dashboards with DAX measures, row-level security, and deployment pipelines

Translate business requirements into semantic layer designs (e.g., Tableau Published Data Sources, Power BI datasets) to enable self-service analytics

Collaborate with analysts and business users to validate reporting outputs against source systems and ensure data accuracy

Stakeholder Collaboration & Documentation

Partner with data engineering, analytics, and business intelligence teams to ensure seamless handoffs and alignment throughout the migration lifecycle

Produce comprehensive technical documentation including mapping specifications, architecture decision records (ADRs), and operational runbooks

Present migration status, risks, and architectural decisions to technical and non-technical stakeholders including senior leadership
