• Vulnerability Management: Conduct continuous asset discovery, automated vulnerability scanning, false positive analysis, and manage the closure and re-testing of identified vulnerabilities.
• Penetration Testing: Perform deep-dive infrastructure, web, mobile application (DAST/manual, OWASP Top 10, OMTG), and segmentation penetration testing.
• Red Teaming & Adversary Simulation: Lead "Assume Breach" simulations, execute complex attack chains (lateral movement, privilege escalation), and develop evasion techniques against security controls.
• Telecom Core Targeting: Conduct specialized attacks against critical telecom systems (OSS/BSS, HLR, VLR, MSC) to identify risks to subscriber data and call routing.
• APT Simulation: Replicate real-world adversary Tactics, Techniques, and Procedures (TTPs) using the MITRE ATT&CK framework.
• Attack Surface Management (ASM): Monitor for "Shadow IT" and exposed digital assets through automated black-box reconnaissance and risk prioritization.
• Dark Web Monitoring: Proactively monitor dark web forums, paste-sites, and messaging channels for leaked telecom-specific data and credentials.
• Reporting & Mentorship: Evaluate Blue Team performance during exercises, and produce high-quality Proof-of-Concepts (PoCs) and remediation roadmaps for technical and executive stakeholders.

Must-Have:

• A minimum of 9+ years in Offensive Security/Red Teaming, specifically within a Telecommunications or ISP environment.
• This is explicitly stated as a minimum required certification is OSCP Certification.

• Foundational Telecom Protocol understanding of SS7, GTP, and Diameter, which is critical for the specified environment.

• Advanced Certifications (OSEP, OSWE, or CRTP): While OSCP is a minimum, possessing one of these advanced certifications demonstrates a higher level of specialized expertise.
• NIST Security Standards Knowledge: Beyond the expert knowledge of MITRE ATT&CK, familiarity with NIST security standards would be a valuable complementary skill.
• Deep Understanding of NOC/SOC Workflows: While a deep understanding of Network Segmentation and Active Directory is listed, specific insight into NOC/SOC workflows would be beneficial for red teamers to understand blue team operations and evasion techniques.
