Anti-Bot Engineer

Responsibilities

• Research and implement anti-bot evasion techniques.
• Reverse engineer bot detection systems. Understand how they work, then bypass them.
• Work with browser fingerprinting: canvas, WebGL, audio, fonts, navigator properties, and more.
• Debug TLS and protocol fingerprinting (JA3, JA4, HTTP/2, HTTP/3 over QUIC, header order and casing), and push the QUIC frontier where most detection and most scrapers haven't caught up yet.
• Optimize Playwright/Puppeteer configurations for stealth.
• Analyze network traffic to understand detection mechanisms.
• Build internal tools for testing and validating evasion techniques.
• Stay ahead of the latest developments in bot detection.
• Document findings and share knowledge with the team.
• You define the work. We don't have a task list for this role. You tell us what you'll work on based on what's broken, what's getting detected, and where you see opportunities. This is how much control you'll have.
