Lead Data Engineer-Apache Iceberg

Position Description
CGI is seeking an experienced Data Engineer to support the migration of a large-scale data platform from Cloudera Hadoop to Apache Iceberg.

This is a critical role in our data modernization initiative, where you’ll help redesign legacy data lake structures and ETL pipelines for modern, cloud-native architecture.
Your expertise in Apache Iceberg, Hadoop ecosystems, and distributed data processing will enable us to achieve improved scalability, schema evolution, performance, and governance across our enterprise data platform.

Your future duties and responsibilities
• Lead the migration of datasets and ETL workflows from Cloudera Hadoop (Hive, Impala, HDFS, etc.) to an Apache Iceberg based architecture.
• Analyze existing data pipelines and storage formats (e.g., Parquet, ORC) to plan and execute a smooth migration strategy.
• Design and implement scalable data ingestion and transformation pipelines using Apache Spark, Flink, or equivalent tools.
• Optimize data partitioning, schema evolution, compaction, and metadata management using Iceberg best practices.
• Integrate Iceberg tables with query engines like Trino or Presto to support data analytics use cases.
• Ensure compatibility and data quality during the migration phase through robust testing, validation, and lineage tracking.
• Establish monitoring, logging, and performance tuning for migrated pipelines and Iceberg tables.
• Document architecture decisions and provide technical guidance to internal teams throughout the migration process. Optimize data ingestion and feature retrieval pipelines for real-time and batch processing.

Required qualifications to be successful in this role
• 6+ years of hands-on experience in data engineering roles, including at least 1-2 large-scale platform migrations.
• Strong expertise with Apache Iceberg, including implementation in production environments.
• Deep understanding of Cloudera Hadoop ecosystem (Hive, HDFS, Impala, YARN).
• Proficiency in distributed data processing frameworks (Apache Spark, Hive, Flink).
• Solid knowledge of data lake architecture, schema evolution, partitioning strategies, and transactional data handling.
• Proficient in Python, Scala, or Java.
• Experience working with orchestration tools such as Apache Airflow, Oozie, or modern equivalents.
• Prior experience migrating from Hadoop to modern Lakehouse platforms (Iceberg, Delta Lake, Hudi).
• Experience integrating Iceberg with BI/SQL tools (e.g., Trino, Dremio, Snowflake).
• Knowledge of data governance, security, lineage, and compliance in enterprise environments.
• Contributions to open-source data projects or cloud data migration tools.
