• Perform security assessments of internal and external networks, infrastructure, cloud environments, and a wide range of internally developed and commercial products.
• Apply creative and analytical thinking to bypass security controls, identify vulnerabilities, and develop practical remediation guidance; stay informed on evolving tactics, techniques, and procedures (TTPs), zero‑day vulnerabilities, and mitigation strategies.
• Develop or modify custom tools and scripts to support new penetration testing needs, automation, and AI‑assisted testing approaches.
• Document and formally report testing scope, methodology, findings, risk ratings, remediation recommendations, and validation results in a clear and concise manner.
• Present testing results to technology and business partners, clearly communicating risk, impact, and remediation guidance in an accessible and collaborative way.
• Lead execution of assigned penetration testing initiatives, including status communication to leadership and coordination with stakeholders.
• Oversee communication, tracking, and retesting of findings to validate successful closure of previously identified issues.
• Assist with validation and triage of submissions from the company’s Vulnerability Disclosure Program and Bug Bounty programs.

Requirements

• 8+ years of experience conducting application, API, and network‑based penetration testing engagements.
• 6+ years of experience troubleshooting tools, manually identifying vulnerabilities in code, and rewriting code to remediate security issues.
• 3+ years of experience leading penetration testing engagements from scoping through reporting and remediation validation.
• 1+ year of experience testing AI, LLM, or Generative AI‑enabled applications.
• 1+ year of experience using AI models (such as Claude or similar) to accelerate tool development or testing workflows.
• Advanced knowledge of security assessment tools and frameworks, such as Burp Suite, Kali Linux, Nessus, Accunetix, Metasploit, AutoSploit, Cobalt Strike, MITRE ATT&CK, MITRE ATLAS, OWASP Top 10 (including OWASP Top 10 for LLMs).

Preferred Qualifications

• Bachelor’s degree or equivalent experience in Information Security, Engineering, Computer Science, or a related field.
• Advanced understanding of OWASP frameworks, MITRE ATT&CK and ATLAS, and secure software development lifecycle (SDLC) practices.
• At least one industry‑recognized certification, such as OSCP, OSCE, OSWE, GPEN, GCIH, GWAPT, or GXPN.
• Advanced proficiency in one or more programming or scripting languages, such as .NET, JavaScript, Python, Java, PowerShell, Perl, Ruby, Bash, or similar.
• Advanced knowledge of Linux, macOS, and Windows operating systems, as well as AWS and Azure cloud environments and cloud‑native services (e.g., containers, Kubernetes, microservices, serverless functions).
• Experience performing reverse engineering on mobile applications, including those with obfuscation or anti‑emulation protections.
• Broad knowledge of operating system security, networking and protocols, firewalls, databases, middleware, forensics, and secure coding practices.
• Effective written and verbal communication skills, with the ability to collaborate with technical and non‑technical stakeholders.
