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.

🎯 Why Join Us?

The deep end of the stack. You work below the browser, in the C++ most people treat as a black box.

Own the moat. The browser is one of our hardest advantages. You own it end to end, not a thin wrapper around it.

Real impact. When you close a detection gap, thousands of customer requests start succeeding immediately.

Rare problems. Few engineers do this work. You'll be the person who can.

Bootstrapped and Profitable. We answer to customers, not investors.

We are searching for grinders who take ownership and go deep. You'll work on some of the hardest problems in web automation.
