O pozici
Browser / Kernel Engineer
We are looking for the browser person. The one who patches Chromium and Firefox at the C++ source level, maintains our in-house patched-browser cloud, and owns the fingerprint surface that makes our automation indistinguishable from a real user on a real machine. Naive JavaScript spoofing gets caught because the implementation underneath gives it away, so you fix it where it actually lives: in the engine. The goal is simple and uncompromising: we own our stealth browser instead of renting one.
About SearchApi
SearchApi is a real-time SERP API delivering structured data from 100+ search engines and sources, including Google Search, Google Shopping, Google Jobs, Bing, Baidu, YouTube, Amazon, and many more. We power production workloads for Fortune 500 companies, AI startups, and developers who need reliable search data at scale.
We're a lean, profitable, bootstrapped team. No VC pressure, no bloat. Just people shipping real products to real customers.
Co budeš dělat
- Own the browser stack. Maintain and evolve our in-house patched-browser cloud and its per-OS fingerprint profiles, kept continuously rebased onto new stable Chromium without regressing the evasions.
- Patch the engine. Fix navigator, WebGL, canvas, fonts, and Client Hints at the implementation level so spoofed values look native, not bolted on.
- Kill CDP leaks. Find and eliminate the signals that give automation away, without breaking normal control.
- Get the details right. Align geolocation, timezone, and locale so the whole picture is consistent.
- Chase detection. When something starts getting flagged, figure out why at the source and fix it.
- Build the tooling. Write the harnesses that test and validate evasions so regressions get caught before customers do.
- You define the work. We don't hand you a ticket queue. You tell us what's getting detected, what's brittle, and what to fix next.
Koho hledáme
- Strong C++. You're comfortable reading and changing a large, unfamiliar codebase and its build system.

- Shipped or contributed to a browser-engine patch, fork, or stealth tool (Chromium, Firefox, camoufox, or similar).
- Understanding of browser fingerprinting and how to spoof it at the implementation level.
- Hands-on with CDP and headless or headful automation internals.
