Nature of work · Data pipeline development
Build and refine Hadoop/Big Data software in Java/Python, turning business requirements into scalable components, tests, and deployable solutions while partnering on requirements and production releases.
""Translate business requirements and source system understanding into technical solutions using Big Data & Java/Python etc.""
Tech stack maturity
Mainstream Legacy
The stack centers on Hadoop, Hive, and Java with Spark/Kafka/Python/SQL, which is a common but still legacy-leaning big-data ecosystem rather than a modern cloud-native one.
