SearchApi is a developer-focused search data platform that provides real-time, programmatic access to search engine results and related web data via HTTP APIs. It offers a wide range of endpoints (Google SERP, Google Maps, Shopping, Images, YouTube, Bing, Baidu, Amazon, eBay, social/ad library APIs, and more), built-in proxy rotation, CAPTCHA solving, precise geo-targeting, and enterprise features like SLAs, team management, and a legal protection guarantee. The service is sold as a pay-per-success API with tiered pricing and integrations for developer workflows and AI/SEO applications.

📋 Description

• 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.

🎯 Requirements

• Strong C++. • Hacker mindset. • Browser internals. • Persistent. • Great writer. • Self-directed. • Fluent in English, written and spoken. • 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. • Familiarity with the Chromium or Firefox build infrastructure and large-scale patch management. • TLS and HTTP fingerprinting awareness. • Experience running browsers at scale. • Contributions to open-source stealth or browser tooling.

🏖️ Benefits

• Fully Remote. Work from anywhere. • Equity share. Own a piece of what you're building. • Profit sharing. When we win, you win. • Learn fast. Touch every part of a growing SaaS. Wear multiple hats. Ship real products to real customers. • Annual team retreats (last one in Spain).
