Section-by-Section Breakdown

Summary

Lead with years of experience, engagement count, and certifications. OSCP and GPEN are table stakes for senior roles.

Skills

Separate offensive security techniques, tools, languages, and frameworks. Name specific tools like Burp Suite Pro and Cobalt Strike.

Experience

Quantify engagements completed, vulnerabilities found, and remediation rates. Include red team dwell time if applicable.

Education

Cybersecurity or CS degrees are standard. Certifications (OSCP, GPEN, OSWE) carry more weight than degrees in this field.

Common Mistakes on Senior Penetration Tester Resumes

  • Not quantifying engagements or findings - 200+ engagements and 350+ vulnerabilities are concrete. 'Performed penetration tests' is not.
  • Listing tools without context - State what you accomplished with each tool. 'Used Burp Suite' vs 'Identified 6 vulnerabilities per engagement using Burp Suite Pro.'
  • Missing certifications - OSCP is nearly mandatory for senior pentester roles. If you have it, put it in the summary and skills section.
  • No red team or social engineering experience - Senior pentesters are expected to go beyond automated scanning. Include red team operations and social engineering if applicable.
  • Omitting responsible disclosure experience - Finding a critical vulnerability in a production system and coordinating disclosure demonstrates maturity and ethics.
