Penetration Tester
UltraViolet CyberFull Time
Senior (5 to 8 years)
Candidates must have over 5 years of penetration testing experience, with at least 3 years focused on iOS and Android mobile applications. Required skills include strong knowledge of OWASP Mobile Top 10 and NIST mobile security guidelines, expertise in static and reverse engineering tools (Apktool, JADX, Ghidra, Hopper, IDA Pro, Radare2, JD-GUI), dynamic and runtime testing tools (Frida, Objection, Cycript, LLDB, Xposed), automation frameworks (MobSF, Drozer, Appium), and proxying/interception tools (Burp Suite Pro, OWASP ZAP, MITM tools). A solid understanding of mobile OS internals, hands-on experience with jailbroken iOS and rooted Android devices, familiarity with cryptography and secure communications, and the ability to think like an attacker are essential. Preferred certifications include OSCP, OSEP, OSED, OSWE, OSMR, EWPTX, EWAPT, CRTP, CRTE, CEH, CAP, or API Security Testing.
The Mobile Application Penetration Tester will conduct end-to-end penetration testing of iOS and Android mobile applications, including static, dynamic, and runtime analysis. Responsibilities include assessing mobile API integrations, authentication mechanisms, encryption protocols, and data storage security, as well as identifying and exploiting vulnerabilities such as insecure data storage, weak cryptography, insecure communication, jailbreak/root bypasses, insecure code practices, and business logic flaws. The role involves using runtime instrumentation frameworks for dynamic testing and bypassing protections, performing certificate pinning bypass, hooking, and traffic interception, and evaluating evasion of mobile app protections. Additionally, the tester will develop custom scripts/exploits, produce comprehensive penetration test reports with remediation steps, work with development and research security teams to embed secure SDLC practices, and contribute to Red Team exercises by simulating adversarial attacks.
