You will drive detailed designs decisions, ensure data quality, and collaborate with cross-functional teams to deliver trusted, analytics-ready datasets. This role also includes mentoring junior engineers and setting engineering best practices to support Mattel’s enterprise data strategy.

Lead the development of scalable, secure, and high-performing data integration pipelines for structured and semi-structured data using Google BigQuery.

Design and develop scalable data integration pipelines to ingest structured and semi-structured data from enterprise systems (e.g., ERP, CRM, E-commerce, Order Management) into a centralized cloud data warehouse using Google BigQuery.

Build analytics-ready pipelines that transform raw data into trusted, curated datasets for reporting, dashboards, and advanced analytics.

Implement transformation logic using DBT to create modular, maintainable, and reusable data models that evolve with business needs.

Apply BigQuery best practices—including partitioning, clustering, and query optimization—to ensure high performance and scalability.

Automate and monitor complex data workflows using Airflow/Cloud Composer, ensuring dependable pipeline orchestration and job execution.

Develop efficient, reusable Python and SQL code for data ingestion, transformation, validation, and performance tuning across the pipeline lifecycle.

Establish robust data quality checks and testing strategies to validate both technical accuracy and alignment with business logic.

Partner with architects and Technical leads to establish best practices, scalable frameworks, and reference implementations across projects.

Collaborate with cross-functional teams—including data analysts, BI developers, and product owners—to understand integration needs and deliver impactful, business-aligned data solutions.

Leverage modern ETL platforms such as Ascend.io, Databricks, Dataflow, or Fivetran to accelerate development and improve observability and orchestration.

Contribute to technical documentation, CI/CD workflows, and monitoring processes to drive transparency, reliability, and continuous improvement across the data engineering ecosystem.

Mentor junior engineers, conduct peer code reviews, and lead technical discussions.

Bachelor’s or Master’s degree in Computer Science, Data Engineering, Information Systems, or related technical field.

Minimum 3 + years of hands-on experience in data engineering with strong expertise in data warehousing, pipeline development, and analytics on cloud platforms.

Expert-level experience in: Google BigQuery for large-scale data warehousing and analytics. Python for data processing, orchestration, and scripting.
