So, how are we going to keep you busy?
Pipeline Architecture: Design, build, and optimize scalable end-to-end data pipelines (ETL/ELT) using Hadoop ecosystem components.
Data Ingestion: Implement high-throughput ingestion pipelines utilizing Apache Nifi or Apache Kafka or Flume to capture streaming event data and transactional batch files.
Distributed Processing: Develop robust data transformation workflows using Apache Spark (Core, SparkSQL, Structured Streaming) and MapReduce.
Data Storage & Modeling: Optimize data layout in HDFS utilizing columnar formats (Parquet, ORC) and manage NoSQL persistence layers using HBase or Cassandra
Query Performance Optimization: Author and tune highly complex distributed queries in Apache Hive to meet tight SLAs.
Orchestration & Workflow Management: Automate and monitor multi-stage pipeline DAGs using orchestration tools like Apache Airflow or Oozie.
Cluster Performance Tuning: Partner with DevOps/Infrastructure teams to debug issues related to data skew, resource allocation (YARN), cluster memory management, and Spark join strategies.
What will make you eligible for this role?
