Responsibilities:

• Lead assigned red-team engagements from scenario design and rules-of-engagement planning through infrastructure build, execution, deconfliction, reporting, and customer out-briefing.
• Develop multi-vector campaigns aligned to MITRE ATT&CK and modern APT profiles, integrating identity-layer exploitation, cloud lateral movement, and infrastructure pivoting.
• Design and oversee adversary infrastructure, redirectors, command-and-control channels, payload-delivery methods, operator access, logging, and teardown procedures.
• Construct secure cloud-based attack infrastructure and teardown workflows consistent with modern adversary tradecraft.
• Lead hands-on execution of advanced identity, endpoint, network, web, cloud, phishing, defense-evasion, persistence, and exfiltration-simulation techniques when authorized.
• Mentor junior operators, review tradecraft and scripts, enforce OPSEC and safety controls, and make real-time technical decisions during operations.
• Review payload/tooling for evasion capabilities (EDR/AV bypass and living-off-the-land techniques) within authorized scope.
• Coordinate with stakeholders to validate detection and response, develop hand-crafted purple-team scenarios, and translate observations into measurable defensive improvements.
• Own technical quality for operator logs, attack narratives, evidence, mitigation recommendations, assessment reports, and customer out-briefs.
• Escalate material risks, scope changes, operational impacts, and cross-engagement issues to the Technical Lead.

• Five or more years of hands-on red-team, defensive-adversary-emulation, or advanced penetration-testing experience, including at least two years leading defensive detection engineering activities and engagements or small operator teams.
• Demonstrated campaign-planning experience across reconnaissance, initial access, credential access, privilege escalation, lateral movement, persistence, command and control, defense evasion, and simulated exfiltration.
• Advanced experience with C2 frameworks, adversary infrastructure, Active Directory/Entra ID, Windows and Linux tradecraft, cloud attack paths, and operator scripting/tool development.
• Strong understanding of operational security, deconfliction, legal/ethical boundaries, evidence handling, and safe execution in production environments.
• Ability to write and technically review assessment reports and deliver clear customer out-briefs to technical and executive audiences.
• Proficiency with advanced tooling (Sliver, Mythic, Havoc) and secure cloud attack architecture.
• One or more advanced hands-on certifications such as OSEP/OSCE, OSCP, GXPN, GPEN, CRTO/CRTL, CRTP, OSED, or equivalent.
