Description
The Senior VAPT Expert manages the end-to-end security assessment lifecycle. This involves conducting broad-spectrum Discovery Scans. They perform deep-dive Infrastructure Penetration Testing. And execute comprehensive Application Penetration Testing. The role also includes high-intensity Red Team/Assume Breach simulations. Beyond identifying vulnerabilities, the expert drives their closure. This ensures mitigation of identified risks across systems. Focus areas include IT and Telecom Core environments (HLR/VLR/OSS/BSS).

Responsibilities
- Conduct continuous asset discovery, automated vulnerability scanning, false positive analysis, and manage remediation tracking with re-testing.
- Execute deep-dive manual infrastructure, web, and mobile application penetration tests, including segmentation testing.
- Plan and execute "Assume Breach" simulations, complex attack chains, and APT simulations using MITRE ATT&CK.;
- Create custom C2 channels and bypass EDR, Antivirus, and WAF controls to demonstrate advanced adversary capabilities.
- Conduct specialized attacks against OSS/BSS,



HLR, VLR, and MSC to identify risks to subscriber data and call routing.
- Monitor for "Shadow IT," exposed digital assets, and leaked credentials through automated reconnaissance.
- Proactively monitor forums and paste-sites for leaked Telecom data (CDRs, MSISDNs, IMEIs) and specific threats.
- Deliver executive-level reports, PoCs, and remediation roadmaps, while evaluating Blue Team detection and reaction times.

Qualifications
Must-Have:
- 9+ years in Offensive Security/Red Teaming, specifically within Telecommunications or ISP environments.
- OSCP certification (minimum) and expert knowledge of the MITRE ATT&CK; framework and NIST security standards.
- Proficiency in Kerberoasting, Pass-the-Hash, Golden Ticket, PowerShell/Bash scripting, and EDR bypass.
- Foundational knowledge of SS7, GTP, Diameter, Network Segmentation, Active Directory, and NOC/SOC workflows.
- Hands-on experie
