📋 Description

• Architect Distributed Stealth Systems: Design and deploy horizontally scalable scraping nodes (Go or Python/Asyncio) on AWS Lambda/Fargate or Kubernetes to maintain massive throughput. • Hidden API Discovery: Use Charles Proxy, Fiddler, or Burp Suite to map out undocumented internal APIs and mobile backend endpoints—finding the "backdoor" pathways that bypass heavy front-end obfuscation. • Fingerprint Evasion: Implement advanced techniques to bypass enterprise-grade bot detection, specifically focusing on TLS fingerprinting (JA3), HTTP/2 headers, and browser fingerprinting evasion. • Orchestrate Massive Infrastructure: Manage large-scale residential and mobile proxy pools to ensure a sustained rate of 1M+ requests per hour while optimizing for cost and success rate. • Build for Resilience: Develop real-time monitoring to track success rates and "burn" rates of proxy infrastructure, ensuring the system can recover automatically when targets update their defenses.

🎯 Requirements

• The "Stealth" Toolkit: Deep experience with Playwright/Puppeteer (when necessary) and custom HTTP clients (e.g., curl_cffi, cycle-tls) for high-speed, headless extraction. • Massive Scale Experience: You have managed data pipelines that process millions of requests daily and understand the nuances of rate-limiting at the IP, session, and header level. • Reverse Engineering Mastery: You are comfortable deconstructing mobile apps or complex JavaScript bundles to find data endpoints. • Builder Mindset: You want to build the "ghost" architecture that runs seamlessly in the background and can be handed off to our core team for long-term maintenance.

🏖️ Benefits

• Technical Sovereignty: We don't care how you get the data, as long as it's efficient and reliable. You own the technical strategy and the stack. • High-Stakes Challenges: You’ll be working against the highest level of web security in existence. • Elite Peer Group: We are a lean, technical team building the data foundation for the AI era.
