Company 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.

Job Description

What You’ll Do

1. 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.

2. 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.

3. 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.

4. 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.

5. 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. Reverse engineering isn’t just a skill—it’s your creative playground.

• Reverse Engineering Expertise: Whether using tools like IDA Pro, Ghidra, or your own solutions, you excel at dissecting binary and web code to uncover core functionalities.

• Web & Network Protocol 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 beyond basic scripting. We’re looking for a coder who can design and implement robust, efficient solutions for complex challenges.

• Collaborative Innovator: While you excel independently, you also thrive in a dynamic team environment that values open communication and continuous learning.

The Challenge

• Technical Questionnaire with hiring manager (15 minutes): Answer real-time technical questions via screen sharing to demonstrate your problem-solving abilities and technical depth.
• Python Challenge (Take-Home): Complete Python exercises to showcase your coding prowess with robust, elegant solutions to complex problems.
• Custom CTF (Home Lab): Tackle a custom anti-bot security challenge to demonstrate mastery in reverse engineering.

If you’re a dedicated code warrior passionate about dissecting and rebuilding systems—and you deliver high-quality, efficient code—send us your resume, GitHub profile, and documentation of your achievements (e.g., CTF wins, write-ups, personal projects). Join Digital Shelf by NIQ and help us reshape the digital frontier.
