Experience with one or more of the following: RDBMS systems; NoSQL data stores (MongoDB, Cassandra, DynamoDB); Hadoop technologies (HDFS, Hive, HBase); or cloud technologies (AWS GovCloud, EMR, S3, DynamoDB, Redshift, Azure Government, Azure file and blob storage). Hands-on scripting and API skills - comfort with Python, Bash, and REST APIs to build custom integrations, automate POV environments, and troubleshoot in air-gapped or restricted networks without vendor support tooling.
