  • Proven expertise in incident response, threat detection, and security operations (SIEM, EDR, DLP, email, endpoint security)

  • Working knowledge of automation, scripting, or infrastructure-as-code (e.g., Python, PowerShell, Terraform, CloudFormation)

  • Familiarity with security frameworks and standards such as NIST, CIS, or equivalent

  • Strong analytical, problem-solving, and communication skills

  • Bachelor’s degree in information security, Computer Science, or a related field (or equivalent experience)

These will help you stand out:
