  • Experience securing cloud environments (AWS, Azure, or GCP)

  • Knowledge of network security, encryption, and authentication mechanisms

  • Experience with vulnerability management and security tooling

  • Familiarity with Linux systems and basic networking

  • Scripting or automation experience (Python, Bash, etc.)
