Penetration Tester Job Description Template

We are looking for a Penetration Tester to give system owners actionable security findings from controlled, authorized engagements. The ideal candidate brings experience in engagement scoping, evidence handling, technical investigation, risk explanation, and remediation verification.

In this role, you will agree the test scope with security and application owners before investigating weaknesses within approved boundaries. You will record evidence with minimal exposure, communicate unexpected risks and respect stop conditions, then help engineering teams understand remediation and validate fixes through authorized retesting.

Penetration Tester Roles and Responsibilities

The Penetration Tester turns agreed priorities into agreed test plans, evidence-backed findings, remediation guidance, and retest reports. Day-to-day work should connect technical or specialist decisions with the needs of security engineers, application owners, developers, and client contacts.

Core duties and responsibilities include:

• Confirm written authorization, target boundaries, permitted methods, timing, and escalation contacts before each engagement.

• Translate engagement goals into a practical test plan covering relevant systems and business-critical workflows.

• Review application designs and access models to identify areas needing deeper authorized investigation.

• Investigate suspected security weaknesses using approved methods while protecting production stability and sensitive information.

• Validate findings sufficiently to explain impact without exceeding agreed boundaries or collecting unnecessary customer data.

• Maintain accurate notes and securely handle evidence according to engagement retention and confidentiality requirements.

• Separate confirmed weaknesses from unverified observations, environmental limitations, and issues requiring further investigation.

• Prioritize findings using technical severity, business context, affected assets, and realistic exposure scenarios.

• Write clear reports describing affected components, supporting evidence, business implications, and practical remediation options.

• Present results to technical teams and business stakeholders, answering questions without overstating certainty or coverage.

• Retest agreed fixes and document whether the original security weakness has been resolved.

• Improve internal checklists and reporting practices using engagement lessons while protecting confidential client information.

Penetration Tester Requirements and Qualifications

Candidates need practical knowledge of authorized security testing, risk communication, and remediation verification and the following role-specific capabilities.

Look for the following skills and qualifications:

• Practical experience investigating application, network, or cloud security weaknesses in explicitly authorized environments.

• Sound understanding of authentication, authorization, network protocols, and common web application security failure modes.

• Working knowledge of Linux and Windows environments relevant to the systems included in the role.

• Comfort using security testing tools critically, validating results rather than relying on automated output alone.

• Clear technical writing that connects evidence, impact, and remediation without unnecessary jargon or dramatic claims.

• Judgment to stop, clarify scope, and escalate when a test could affect availability or sensitive information.

• Familiarity with secure evidence storage, client confidentiality, and responsible handling of vulnerability details.

• Scripting skills for repeatable analysis and reporting tasks within approved testing environments.

• Experience discussing remediation with developers and balancing security improvements with operational constraints.

• Relevant security projects, professional practice, or certifications supported by credible explanations of personal contribution.

Who Does a Penetration Tester Report To?

A Penetration Tester needs a reporting relationship that supports authorized engagement scope, review of findings, and escalation when testing reaches a stop condition. Application owners and client contacts are engagement partners rather than necessarily line managers. Possible reporting titles include:

• Penetration Testing Manager

• Head of Offensive Security

• Security Consulting Manager

• Director of Information Security

Clarify who sets priorities, reviews specialist decisions, and manages professional development when those responsibilities sit with different leaders.

How to Assess Penetration Tester Skills Effectively

Start with an engagement brief and sanitized finding to examine authorization, supported impact claims, stop conditions, and useful remediation guidance rather than the number of weaknesses named. Explain permitted tools in advance and give candidates consistent briefs.

• Review a fictional engagement brief and identify missing authorization details, boundaries, stop conditions, and communication responsibilities.

• Read a sanitized vulnerability report and explain which claims are supported, which need clarification, and how to improve remediation guidance.

• Prioritize several fictional findings using asset sensitivity, exposure, existing controls, and business consequences rather than severity labels alone.

• Discuss an unexpected production issue during an authorized test and describe safe escalation, documentation, and pause decisions.

• Explain a technical finding to a nontechnical product owner, emphasizing business impact without revealing unnecessary sensitive details.

• Plan a retest for a resolved issue and describe the evidence needed to support a qualified closure statement.

Ask candidates to explain trade-offs and compare their answers against consistent interview criteria.
