-   Cloud Environments (Optional/Nice to Have): (AWS, Azure, GCP configuration reviews and exploitation).
-   Tooling: Utilize and refine advanced tooling (Burp Suite Pro, Metasploit, Nmap, Nessus, Bloodhound, etc.) and develop custom scripts/exploits when automated tools fail.
-   Client Engagement & Consulting:
-   Scoping: Collaborate with clients to define engagement scope, rules of engagement (RoE), and timelines.
-   Communication: Serve as the primary technical point of contact during engagements, providing status updates and immediate alerts on critical "showstopper" findings.
-   Reporting: Author high-quality, executive-level reports that translate technical vulnerabilities into business risks. Must be able to explain the "So What?" to C-level executives and the "How To Fix It" to system administrators.
