Get started

Penetration testing is one of the most in demand roles in offensive cyber security today. Recruiters and hiring teams need candidates who can proactively find security bugs before attackers do, and who can turn what they find into a clear, actionable report that improves the organization’s security posture.

This penetration tester job description template covers the responsibilities, required skills, and a typical day in the role, so you can adapt it to your organization’s specific environment and use it as the foundation for a skills based hiring process.

Penetration Tester Job Description

We are hiring a penetration tester who can act as a custodian of cyber security and configuration settings across the enterprise. This role is a fit for candidates who are comfortable launching adversarial attack simulations and protecting data integrity under realistic conditions.

Strong candidates are fluent in network and application security, penetration test management platforms, and security assessment tooling. Prior experience with bug bounty programs, Open Source Intelligence (OSINT), and proprietary attack programs is a strong plus.

Key Responsibilities

  • Examine target domains, subdomains, and their associated flaws
  • Use tools like Sublist3r, Aquatone, Nikto, Dig, and Nessus to map attack surface
  • Formulate vulnerability findings with reproducible proof of concept steps for clients
  • Engage with the security community on trends in newly exploited vulnerabilities
  • Expand and improve existing processes and tooling used for vulnerability validation
  • Contribute to signatures used in automated vulnerability detection products
  • Support vulnerability identification across customer programs
  • Write clear reports that include proof of concept detail for every finding

What We Are Looking For

  • Advanced degree in Computer Science, IT, or Systems Engineering (nice to have, not required)
  • Proficiency in programming languages like Python, PowerShell, Golang, and Bash
  • Experience working across network operating systems including Linux, MacOS, Windows, iOS, and Android
  • Familiarity with penetration test and application security tools like Kali, Burp Suite, and Metasploit
  • Working knowledge of the dark web, CSRF, SSRF, and current vulnerability trends
  • Certifications from IEEE, OSCP, GIAC, or EC Council are strongly preferred

A Day in the Life of a Penetration Tester

A typical day blends deep technical work with communication. Testers spend time examining target subdomains and known flaws, running tools like Sublist3r, Aquatone or HostileSubBruteForcer, Nikto, Dig, and Nessus, and formulating vulnerability findings with reproducible proof of concept steps for clients.

Beyond hands on testing, the role includes staying current on how known vulnerabilities are being exploited in new ways, improving internal tooling used for vulnerability validation, contributing to detection signatures, and writing clear, well documented reports that give clients a concrete path to remediation.

Frequently Asked Questions

What does a penetration tester do?

A penetration tester simulates real world cyber attacks against an organization’s systems, networks, and applications to find security weaknesses before malicious actors can exploit them, then documents findings with proof of concept detail.

What certifications should a penetration tester have?

Common and well regarded certifications include OSCP, GIAC certifications, EC Council’s CEH, and other IEEE recognized credentials, though hands on skill validation matters as much as certification alone.

What is the difference between a penetration tester and an ethical hacker?

The terms are often used interchangeably. In practice, penetration tester tends to describe a formal, scoped engagement role, while ethical hacker is a broader term that can include bug bounty and research work as well.

What programming languages should a penetration tester know?

Python, PowerShell, Golang, and Bash are the most commonly required languages, since they support scripting exploits, automating reconnaissance, and building custom tooling.

How do I evaluate a penetration tester’s skills before hiring?

Structured, hands on skill assessments and live coding or scenario based interviews are more reliable indicators than a resume or certification list alone, since they show how a candidate actually approaches a target.

What tools should a penetration tester be comfortable using?

Look for familiarity with tools like Kali Linux, Burp Suite, Metasploit, Nessus, and Nikto, along with reconnaissance tools such as Sublist3r and Aquatone.
