Descripción de la vacante

NielsenIQ’s Digital Shelf division seeks a highly skilled security-focused engineer to reverse engineer and decompile mobile and web apps, uncover cryptographic mechanisms, and bypass anti-bot defenses. You will craft Python tools to automate bypass procedures, modify TLS stacks, and patch JavaScript to adapt defenses while maintaining ethical standards.

You will implement stealth scraping techniques, including browser patching, headless evasion, and proxy tunneling, to gather data discreetly.

Formación

• Expertise in reverse engineering and decompilation of binaries and mobile apps with a focus on cryptographic functions.
• Experience bypassing modern anti-bot and security protocols (TLS, HTTP/2/3, WebSockets, DoH).
• Developing robust Python tools to automate bypass procedures and dynamic security adjustments.
• Designing stealth scraping techniques including browser patching and headless evasion.
• Continuous innovation to stay ahead of evolving defenses.

Responsabilidades

• Analyze apps and decompile to uncover hidden mechanisms and cryptography usage.
• Evaluate and bypass security protocols to enhance data extraction methods.
• Build Python scripts and frameworks to automate bypass and adjust TLS stacks.
• Implement stealthy scraping techniques like browser patches and proxy tunneling.
• Regularly test and improve tools to outpace evolving defenses.

Descripción del empleo

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.

Job Description

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. R3v3rs3 3ng1n33r1ng 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 pr0t0c0ls 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.
