Job Description:

At HPE's Cyber Defense Center, we are committed to defending critical assets against ever-evolving cyber threats. As we enhance our capabilities, we're seeking a strategic leader who can harness their hands-on experience to help mature our First Response and Incident Command Team. This role calls for someone who can drive operational effectiveness under stress in a fast-paced and cyber environment.

Are you ready to make an impact at one of the world's leading tech companies? HPE's Cybersecurity team is where you can do just that! We're looking for a dynamic and experienced offensive security expert to join our Offensive Security Special Ops team. If you're passionate about shaping the future of cybersecurity by applying offensive security skills to make defense better, join us!

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.

Candidates should demonstrate deep expertise in at least four domains (Web Penetration Testing and three more) plus practical experience in the remaining domains. For the Senior Principal level, we expect both strong depth in multiple domains and the ability to lead technically across multiple domains:

• Web Penetration Testing
• Application Penetration Testing
• Cloud Penetration Testing (AWS, Azure, and GCP)
• Source Code Security Review
• Threat Modeling and SDLC
• Testing AI&ML Systems

What You'll Do:

• Performing advanced assessments of web applications, APIs, and authentication mechanisms to identify and exploit vulnerabilities across modern frameworks and architectures. Delivering actionable findings that directly inform defensive improvements.
• Conducting offensive security assessments in AWS, Azure, and GCP environments. Testing identity, networking, storage, and serverless components to uncover misconfigurations and privilege escalation opportunities in multi-cloud deployments.
• Reviewing application and infrastructure-as-code repositories to identify insecure coding patterns, injection points, and logic flaws. Collaborating with development teams to remediate vulnerabilities early in the SDLC.
• Partnering with engineering and product teams to identify potential attack vectors at the design phase. Performing structured threat modeling to ensure security is embedded throughout the software development lifecycle.

What You Need to Bring:

• Ability to take ownership of the technical planning and delivery of penetration testing engagements — from scoping and test plans through exploitation, PoC development, remediation verification, and formal reporting.
• Proven offensive web/app expertise: Demonstrated experience performing advanced web and API penetration tests, exploiting authentication/authorization flaws, business-logic issues, injection classes, and modern frameworks.
• Cloud exploitation: Hands-on experience testing and exploiting workloads and configurations in AWS, Azure, and GCP (identity, networking, storage, serverless, IaC).
• Server & client platform familiarity: Strong experience with common server and client platforms that host or interact with web apps—Linux and Windows primary; macOS experience is a plus.
• Programming & automation: Strong scripting and tooling skills using Python, Go, or C/C++ (or equivalent) to automate testing, build proofs-of-concept, and develop internal pentest tools.
• Infrastructure & evasion: Experience deploying offensive infrastructure for engagements and evading/demonstrating bypasses of network and host-based controls (WAF, IDS/IPS, EDR).
• Source code review & SDLC: Experience performing secure code reviews and integrating findings into the SDLC through threat modeling, developer collaboration, and security-by-design recommendations.
• Experience level & education: Master's degree in Cybersecurity, Computer Science, Information Technology, or equivalent experience. Minimum 9+ years in cybersecurity with substantial focus on offensive security and web/cloud testing.
• Research & innovation: Documented history of meaningful technical research, responsible disclosure, tooling contributions, or industry-visible findings (e.g., novel vulnerabilities, exploit techniques, or defensive improvements).

Nice-to-Have:

• Ability to assess ML/AI components integrated into web and cloud products — including model endpoints, inference APIs, training pipelines, and MLOps — to identify risks from prompt injection, model poisoning, data leakage, and adversarial examples.
• Ability to design and automate adversarial tests and prompt-fuzzers to evaluate AI model robustness, and deliver mitigation guidance to product and detection teams.
• Credited CVE's, participation in bug bounty programs, security blogging, publicly available quality code or tools.

Preferred Certifications/Experience:

• Certifications such as OSCP / OSCE, GPEN, GWAPT, CRTP, OSWE, or equivalents.
• Experience with CI/CD and developer pipelines security (GitHub/GitLab runners, build agents, IaC scanning).
• Familiarity with threat emulation frameworks and MITRE ATT&CK, OWASP TOP 10, OWASP ASVS, OWASP WSTG, STRIDE, and mappings for web/cloud scenarios.
• Experience authoring pentest playbooks, reusable test modules, or internal offensive tooling.

Deliverables & Success Metrics:

Key deliverables include detailed test plans, high-fidelity technical reports with PoCs, remediation verification summaries, reusable playbooks/test modules, and tooling contributions. Success will be measured by the quality of findings, remediation impact, reduction in repeat issues, and improvements to detection/response coverage.

Additional Skills:

Accountability, Action Planning, Active Learning, Active Listening, Agile Methodology, Bias, Business, Coaching, Creativity, Critical Thinking, Cybersecurity, Data Analysis Management, Data Collection Management (Inactive), Data Controls, Design Thinking, Development Methodologies, Empathy, Follow-Through, Growth Mindset, Implementation Methodologies, Infrastructure Design, Intellectual Curiosity (Inactive), Long Term Planning, Managing Ambiguity

What We Can Offer You:

Health & Wellbeing: We strive to provide our team members and their loved ones with a comprehensive suite of benefits that supports their physical, financial, and emotional wellbeing.

Personal & Professional Development: We also invest in your career because the better you are, the better we all are. We have specific programs catered to helping you reach any career goals you have — whether you want to become a knowledge expert in your field or apply your skills to another division.

Unconditional Inclusion: We are unconditionally inclusive in the way we work and celebrate individual uniqueness. We know varied backgrounds are valued and succeed here. We have the flexibility to manage our work and personal needs. We make bold moves, together, and are a force for good.
