Responsibilities

Data and Database Migration:

• Actively participate in the design and execution of the data and ETL process migration strategy from SQL Server to GCP.
• Develop and optimize scripts and pipelines for efficiently transferring and transforming data into BigQuery.

Design and Development of Data Pipelines on GCP:

• Design, develop, and maintain robust and high-performing ETL/ELT pipelines on GCP, replacing or rebuilding existing flows.
• Orchestrate and schedule these pipelines using Google Cloud Composer (or Apache Airflow) to ensure reliable migration and operationalization.

Database Management and Optimization on GCP:

• Develop and optimize complex SQL queries for BigQuery, taking into account the specificities of migrating from SQL Server to BigQuery (e.g., optimizing partitioning, clustering).
• Contribute to the design and implementation of optimized data schemas for BigQuery, adapted to new cloud architectures.

Development and Automation:

• Use Python to develop scripts for automating migration tasks, data transformation, and integration with other GCP services.
• Implement processes to ensure data quality and integrity during and after migration.

Collaboration and Support:

• Collaborate closely with current teams (SQL Server administrators, analysts) to understand the existing environment and facilitate the transition.
• Exchange with end-users (business lines, data scientists) to understand their needs and ensure the new platform meets their expectations.
• Participate in code reviews, development best practices, and testing strategies for the new platform.
• Ensure monitoring, debugging, and incident resolution related to data pipelines during the transition phase and upon production deployment.

Technological Watch and Optimization:

• Stay informed about best practices for migration and the latest developments on Google Cloud Platform.
• Propose improvements and optimizations for the new Data platform on GCP.

Hard skills:

• Mastery of Google Cloud Platform (GCP):
  • BigQuery: Significant experience in schema design, writing complex queries (SQL), performance optimization, and cost management in a cloud context.
  • Cloud Composer / Apache Airflow: Solid experience in creating, scheduling, monitoring, and debugging DAGs to orchestrate data flows, particularly for migration and integration processes.
• SQL: Excellent mastery of the SQL language. Experience with SQL Server is a plus, but more importantly, the ability to adapt and optimize SQL for BigQuery.
• Python: In-depth mastery of the Python language for developing scripts (migration, automation, data transformation) and interacting with GCP APIs.
• Data Migration: Experience or strong understanding of the challenges and methodologies for migrating databases from an on-premise environment (SQL Server) to a cloud environment (GCP).
• Analytical and Problem-Solving Skills: Ability to analyze existing systems (SQL Server), understand business needs, design solutions on GCP, and resolve complex problems related to migration and pipeline operation.
• Good communication skills in English (B2 level required).

Additional Skills (Good to Have):

• Direct knowledge of SQL Server (architecture, T-SQL, basic administration).
• Experience with other GCP services relevant to data migration and integration (Storage, Dataflow, etc.).
• Knowledge of GCP-specific migration tools and strategies (e.g., Database Migration Service).
• Experience with data visualization tools (Power BI).
• Understanding of Data Warehousing concepts and data modeling (Data Vault).
• Experience with code versioning.

Soft skills:

• Autonomy, rigor, organizational skills, teamwork ability, technical curiosity, and the capacity to adapt to a new environment.
