Responsibilities

• Reverse engineer web and mobile applications (APK/IPA) by disassembling code, with a focus on the cryptographic functions that protect the company's systems.
• Assess advanced security protocols including TLS, HTTP/2, HTTP/3, WebSockets, DoH, and session management, and bypass them. Find vulnerabilities that improve the company's data extraction methods.
• Write robust Python scripts and frameworks that automate bypass procedures and adjust security measures on the fly, by modifying TLS stacks or patching JavaScript.
• Build stealthy scraping methods such as browser patching, headless browser evasion, proxy tunneling, and human-behavior emulation to keep operations discreet.
• Test, break, and improve the tools on a regular basis to keep pace with defenses that keep changing.

Requirements

• Experience with reverse engineering tools such as IDA Pro or Ghidra, or with your own custom tools, and the ability to analyze both binary and web code to find core functionality.
• Deep knowledge of protocols including TLS, HTTP/2, WebSockets, DoH, and others, and the ability to use it to find new solutions.
• Advanced Python skills. You can design and build robust, efficient solutions for complex problems, not just basic scripts.
• Ability to work independently and also in a dynamic team that values open communication and continuous learning.
• Ethical standards that are high enough to work on offensive security techniques responsibly.
• To apply, send your resume, GitHub profile, and documentation of technical work such as CTF results, write-ups, or personal projects.
