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 https://www.searchapi.io/ 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. 💻 TECH STACK - Chromium and Firefox source (C++) - The Chromium build system (gn, ninja) and continuous rebasing - Chrome DevTools Protocol (CDP) - Per-OS fingerprint profiles: navigator, WebGL, canvas, audio, fonts, Client Hints - The open-source stealth ecosystem: camoufox, rebrowser-patches, patchright, nodriver, ungoogled-chromium - Ruby, Node.js, or Python for tooling, plus AWS We use Cursor, Claude, GitHub, and Slack daily. We ship multiple times a day with CI/CD. 🤖 YOU CONTROL AI, AI DOESN'T CONTROL YOU We ship faster because we use AI tools aggressively, Cursor and Claude. But a giant C++ codebase punishes blind trust. You use AI to navigate and move fast, and you own every patch that lands. If you can't evaluate what it produces, you're not ready for this role. 💪 WHAT YOU'LL DO - 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. 🔥 THE HARD PARTS This role is not for everyone. Here's what makes it hard: - The rebase treadmill. Upstream never stops moving. Keeping patches alive across new releases is constant, unglamorous work. - A massive unfamiliar codebase. Chromium is enormous. You'll be productive in a corner of it long before you understand the whole. - Cat and mouse. What works today can be detected tomorrow. You adapt, forever. - Lonely expertise. Few people understand this domain deeply. You'll often be figuring it out alone. - Long debugging. Some leaks take days to isolate. If you want
