• Analyze logs, endpoint artifacts, and network telemetry during exercises or assessments to help validate whether adversary behaviors are detected and escalated appropriately.
• Write and present clear, evidence-based reports that document findings, affected assets, exploitability, business or mission impact, and prioritized remediation recommendations.
• Deliver technical and executive out-briefs to client stakeholders, including system owners, security operations teams, engineering teams, and senior leaders.
• Stay current on emerging attack techniques, offensive tooling, detection approaches, and federal cybersecurity requirements, and apply that knowledge to strengthen client security posture.

• One or more relevant offensive security certifications such as OSCP, GPEN, GWAPT, GXPN, GRTP, PenTest+, CEH, GCIH, or similar certification.
• Experience with adversary emulation, purple team operations, detection engineering support, or validation of SIEM and EDR detection coverage.
• Experience with Cobalt Strike, Sliver, custom payload development, or command-and control simulation in approved assessment environments.
• Experience with cloud security testing or assessment activities across AWS, Azure, or other cloud environments.
• Experience supporting incident response, threat hunting, or post-incident analysis.
