• 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.
