  • Demonstrated experience building and operating data platforms or large‑scale data services in production
  • Proven track record of building services from the ground up (requirements → design → implementation → deployment → ongoing ownership)
  • Hands‑on experience with AWS, GCP (e.g., compute, storage, data, and streaming services) and cloud‑native architectures
  • Practical experience with big data technologies, such as Databricks, Apache Spark, AWS EMR, Apache Flink, or StarRocks
