The successful candidate will deliver high-confidence, reproducible vulnerabilities with clear evidence and practical remediation guidance, and partner with application teams to drive timely fixes.

Responsibilities:

• Conduct application penetration testing across browser-based/web applications, APIs, and mobile applications (and where applicable mainframe and thick client applications) using primarily manual techniques supplemented by automated tools
• Include authentication/authorization testing and business-logic abuse cases where applicable
• Configure and tune automated tools to support testing, improve coverage, and accelerate discovery (as a complement to manual testing)
• Perform deep defect analysis by reproducing, validating, and safely demonstrating impact (including chained attack paths when applicable)
• Triage and disposition false positives from automated tooling
• Produce clear, reproducible technical reports with evidence (steps to reproduce, impacted components/endpoints, and risk/impact) and practical remediation guidance
• Collaborate with application and security teams to ensure shared understanding of defects, prioritization, and remediation paths
• Support continuous improvement of testing methodologies and processes leveraging industry standards and best practices
• Collaborate with other members of the team to share knowledge and complete peer reviews of reports
• Communicate findings and risk clearly to technical and non-technical stakeholders

Requirements:

• 4 years of Cyber Security Research experience, or equivalent demonstrated through one or a combination of the following: work or consulting experience, training, military experience, education
• 2 years of hands-on application penetration testing experience (manual testing required), beyond reviewing/validating automated scanner results
• 2 years of Dynamic Application Security Testing (DAST) experience, including tool configuration/tuning and manual verification of findings

Desired skills:

• Advanced experience with testing tools such as Burp Suite, Invicti, WebInspect, and Fiddler
• Strong knowledge of application security and common vulnerabilities (OWASP Top 10)
• Experience with scripting and automation (e.g., Python, Shell)
• Knowledge of security best practices and compliance standards (e.g., PCI DSS, GDPR)
• Excellent communication skills and the ability to collaborate effectively with cross-functional teams
• Strong problem-solving and analytical skills
• Demonstrated knowledge of AI/ML-enabled applications and common security risks (for example, prompt injection, sensitive data exposure, and insecure integrations)
• Security certifications such as OSCP, BSCP, GWAPT, GPEN, GXPN or equivalent are a plus
