Job summary

SearchApi is seeking an engineer obsessed with breaking through anti-bot systems. You will tackle fingerprinting, TLS handshakes, and headless browser detection at scale, using Playwright, Puppeteer, and related tooling.

We offer a fully remote role with equity and profit sharing. You will own research, reverse engineering of detections, and build internal tools to test evasion techniques, documenting findings for the team.

Qualifications

Deep experience with Playwright, Puppeteer, or Selenium internals.
Understanding of browser fingerprinting techniques and how to spoof them.
Experience bypassing at least one major anti-bot system (Cloudflare, Akamai, DataDome, PerimeterX, etc.).
Network traffic analysis (Wireshark, Burp Suite, mitmproxy, or similar).

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.
