  • Practical cloud-native experience, in AWS (compute, storage, networking, security).
  • Proficiency with Databricks/Spark for large-scale data processing; strong coding skills in Python and Java; familiarity with data pipelines and controls.
  • Experience in Computer Science, Engineering, Mathematics, or a related field, with expertise across core technology disciplines (APIs, data, platform engineering).
