  • Strong experience with static and dynamic analysis of Android and iOS applications, including hands-on experience with techniques like detours, hooking, and runtime code manipulation
  • Deep, hands-on knowledge of the latest tactics, techniques, and procedures (TTPs) used in advanced penetration testing and network analysis.
  • Ability to author comprehensive and technically rigorous reports detailing identified vulnerabilities and research outcomes.

Nice to have:

  • OSCP, OSWE, eWPTXv2, CRTP, or other high-level offensive certifications.
  • Hands-on experience with industry-standard reversing tools like JADX, Ghidra, or IDA Pro.
  • Demonstrated online achievements, write-ups, or contributions on platforms such as HackTheBox, Pwn2Own, TryHackMe, Bug Bounty programs, or published security research.
