• Basic Hive query development and troubleshooting
• Understanding of data ingestion and batch processing workflows
• Experience working with Hadoop-based data platforms in support of application development
• Exposure to Spark is a plus
Note: Hadoop is a secondary skill. Candidates are not expected to perform deep Hadoop administration, cluster management, or advanced big-data engineering.
Preferred Skills
• Apache Spark
• NoSQL Databases (Cassandra/MongoDB)
• Splunk, Dynatrace
• AWS, Azure, or Google Cloud Platform
