Job description

Overview

Company: 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.

Your Profile / Qualifications

• P45510n4t3 C0d3 W4rr10r: You thrive on pushing systems to their limits while upholding the highest ethical standards. Reversing engineering isn’t just a skill—it’s your creative playground.
• R3v3rs3 3ng1n33r1ng Expertise: Whether using tools like IDA Pro, Ghidra, or your own custom-built solutions, you excel at dissecting both binary and web code to uncover core functionalities.
• W3b & N3tw0rk Pr0t0c0l Savant: You possess deep expertise in protocols such as TLS, HTTP/2, WebSockets, DoH, and more, leveraging that knowledge to find innovative solutions.
• Advanced Python Developer: Your coding abilities go far beyond basic scripting. We’re looking for a true coder—someone who can design and implement robust, efficient solutions for complex challenges.
• Collaborative Innovator: While you excel as an independent problem-solver, you also thrive in a dynamic team environment that values open communication and continuous learning.

Our Benefits

• Flexible working environment
• Volunteer time off
• LinkedIn Learning
