Proficiency in Java, Scala, or Go, with strong foundations in algorithms, data structures, and system design.
Expertise in distributed data systems such as Kafka, Spark, Flink, or HDFS.
Experience designing and operating large-scale services on cloud platforms (AWS, GCP, Azure, or private cloud).
Understanding of data governance, cataloging, and orchestration frameworks.
Strong communication and collaboration skills, with the ability to influence technical strategy across diverse teams.
