• At least five years of relevant professional experience in vulnerability assessments and penetration testing.
• At least one recognised penetration testing or cybersecurity certification, such as CREST, OSCP, GPEN, InfoSec CEPT, CEH or PenTest+.
• Practical experience identifying, validating and documenting technical vulnerabilities.
• The ability to analyse security risks and recommend appropriate remediation measures.
• Strong analytical thinking, problem-solving and technical documentation skills.
• The ability to work independently and deliver within defined project timelines.
• Willingness and availability to attend onsite testing activities in Pretoria when required.

What Success Looks Like
