• Basic understanding of computer systems, networking, and security fundamentals

• Basic knowledge of common security concepts (e.g., vulnerabilities, authentication, OWASP Top 10)
• Exposure to programming or scripting (Python, Go, or Bash)
• Strong problem-solving skills and attention to detail
• Eagerness to learn and take ownership of tasks

Preferred Knowledge and Skills:

• Familiarity with containers (Docker) and basic Kubernetes concepts
