Senior Adversarial Infrastructure Engineer

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.

Why Join Us?

- 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.
