This role provides advanced offensive cybersecurity expertise, focusing on the planning and execution of complex Web and Cloud penetration testing engagements. You will own the technical planning and delivery of penetration testing engagements — from scoping and test plans through exploitation, PoC development, remediation verification, and formal reporting.

You will apply a deep technical skills and offensive security experience to identify and exploit vulnerabilities in enterprise and cloud environments, helping to strengthen defenses through hands-on testing and analysis. This position involves driving high-impact testing projects, developing new testing methodologies and tools, and contributing to the organization's overall security posture by uncovering and demonstrating real-world attack paths.

You have deep expertise in identifying and exploiting vulnerabilities across web, applications, and cloud environments. Your offensive skill set spans modern web frameworks, authentication mechanisms, and API ecosystems, as well as cloud-native architectures in AWS, Azure, and GCP. You are experienced in performing comprehensive security reviews of source code and conducting threat modeling to identify design-level weaknesses early in the SDLC. You stay current with evolving attacker TTPs and apply that knowledge to perform realistic and high-impact penetration tests that strengthen HPE's defenses and improve the security of our products and platforms.
