About the role
About RevenueBase We're building the data infrastructure that makes AI agents trustworthy instead of error-prone. We provide continuously refreshed, verified B2B data and tools for humans and autonomous AI agents. The Opportunity: High-Scale Stealth Engineering We are looking for an elite Senior Adversarial Infrastructure Engineer on a contract bais to lead our high-scale data enumeration initiatives. This isn't a "scripting" job—it is a sophisticated engineering challenge. You will be responsible for building and scaling systems capable of processing 1 million+ records per hour against some of the most well-defended enterprise platforms on the web. You are the right person if you find standard browser automation "too loud" and prefer hunting for undocumented mobile APIs, reverse-engineering private endpoints, and staying one step ahead of world-class anti-bot teams. What You’ll Do 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. What We’re Looking For 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.
