Overview


We are seeking a Data Engineer with strong Apache NiFi expertise to design and implement pipelines that move and transform data from Cloudera (HDFS/Hive/Impala) into Apache Iceberg tables, with downstream integration into Snowflake and Databricks. The ideal candidate will have hands-on experience with modern data lakehouse architectures and will play a critical role in enabling scalable, governed, and high-performance data platforms.


Key Responsibilities:


  • Data Ingestion & Pipeline Development
  • Design, configure, and maintain NiFi data flows to extract, transform, and load data from Cloudera into Iceberg tables.
  • Implement streaming and batch ingestion pipelines with NiFi processors and custom scripting where needed.
  • Optimize NiFi workflows for scalability, reliability, and monitoring.
  • Data Lakehouse Enablement
  • Build and manage Apache Iceberg-based datasets for structured, semi-structured, and unstructured data.
  • Ensure schema evolution, partitioning, and metadata management in Iceberg.
  • Develop integration flows from Iceberg to Snowflake and Databricks for analytics, ML, and reporting use cases.
  • Integration & Orchestration
  • Work with Snowflake to ingest curated data from Iceberg for enterprise reporting and commercial insights.
  • Collaborate with Databricks teams to enable advanced analytics and machine learning use cases.
  • Integrate NiFi pipelines with orchestration tools (Airflow, Oozie, or AWS/Azure/GCP schedulers).
  • Performance, Security & Governance
  • Tune NiFi flows and Snowflake/Databricks ingestion for performance and cost optimization.
  • Implement role-based security and ensure compliance (HIPAA, GDPR, SOX if applicable).
  • Work with governance teams to enable lineage, metadata tracking, and auditability.


Qualifications:


  • Bachelor’s degree in Computer Science, Information Systems, or related field.
  • 5+ years of data engineering experience, with at least 2+ years working with Apache NiFi.
  • Strong experience with Cloudera ecosystem (HDFS, Hive, Impala, Spark).
  • Hands-on expertise with Apache Iceberg (schema evolution, time travel, partitioning, compaction).
  • Working knowledge of Snowflake and Databricks integration patterns.
  • Proficiency in SQL and one programming language (Python, Java, or Scala).
  • Understanding of data lakehouse architectures and ETL/ELT best practices.
