Full Job Description

At Digital Shelf by NIQ, we’re passionate about technological innovation and excellence in cybersecurity. Our cutting-edge solutions enable us to scrape data for 12 billion products and manage over 20 billion data points. In a market where anti‑bot technologies represent a $10B industry in constant evolution and consolidation, our dedicated teams tackle real‑world challenges with precision and creativity. What You’ll Do * Reverse Engineering & Decompilation: Analyze web and mobile applications (APK/IPA) to uncover hidden mechanisms. Disassemble code to understand its inner workings, with a focus on cryptographic functions that secure our systems. * Overcoming Anti‑Bot Mechanisms: Evaluate and bypass advanced security protocols such as TLS, HTTP/2, HTTP/3, WebSockets, DoH, and session management. Identify vulnerabilities to enhance our data extraction methods. * Developing Custom Tools: Build robust Python scripts and frameworks that automate bypass procedures and dynamically adjust security measures—whether by modifying TLS stacks or patching JavaScript on the fly. * Implementing Stealthy Scraping Techniques: Engineer sophisticated methods—such as browser patching, headless browser evasion, proxy tunneling, and human‑behavior emulation—to keep our operations discreet. * Continuous Innovation: Regularly test, disrupt, and improve our tools to stay ahead of ever‑evolving defenses. ## Qualifications Your Profile * P45510n4t3 C0d3 W4rr10r: You thrive on pushing systems to their limits while upholding the highest ethical standards.
