Proven expertise in incident response, threat detection, and security operations (SIEM, EDR, DLP, email, endpoint security)
Experience with vulnerability management, risk assessment, and remediation tracking
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:
Relevant certifications such as Security+, CySA+, GCIH, GCIA, AWS Security Specialty, AZ-500, SC-200
Experience with Zero Trust architecture, CNAPP/CSPM, IAM/PAM, and container security
Exposure to application security (AppSec) practices and tools
Experience supporting threat hunting, purple team exercises, or security automation initiatives
