The ideal candidate will emulate advanced persistent threat (APT) tactics, discover hidden exploit vulnerabilities, and write technical proof-of-concept reports to help software engineering and infrastructure teams systematically harden corporate defenses.

Key Responsibilities

Execute comprehensive network and web application penetration tests , utilizing automated scanning suites alongside manual exploration tactics to expose system vulnerabilities. Conduct realistic red-teaming simulation campaigns , probing corporate defenses, orchestrating advanced social engineering scenarios, and bypassing physical perimeter monitoring configurations.

Develop structural custom exploitation scripts (e.g., Python , Power. Shell , Bash) to demonstrate vulnerability severity while respecting operational stability guidelines. Triage and evaluate cloud infrastructure entry vectors , assessing multi-tenant environment perimeters, microservice containers, API authentication weaknesses, and misconfigured access permissions.

Document and present highly detailed vulnerability disclosure reports , assigning clear impact scoring (CVSS), defining business risk matrices, and detailing step-by-step technical remediation paths. Perform rigorous post-remediation verification sweeps , re-testing patched software frameworks, validated infrastructure updates, and newly implemented defensive logic barriers.
