We're looking for a Chromium Android Engineer to join Datos, a Semrush Company - a integral provider of anonymized, aggregated, fully compliant first-party clickstream data. You'll work on the technology behind our mobile data collection panel. You will own and support our mobile browser, which is our Android panel client:



a maintained fork of Chromium (Chrome for Android, currently milestone 140), not a WebView wrapper.

• Build product UI inside the Chromium Android shell (toolbar, new-tab page, settings, onboarding, dialogs), following existing chrome/android patterns rather than a standalone app architecture.
• Maintain the native content-filtering stack: C++ filter matching, the JNI bridge, cosmetic filtering via script injection into WebContents, and updates of filter lists (including server-delivered rules).
• Maintain compliance with Google Play policies and data privacy regulations (GDPR and similar).
• Own the Android release surface: GN/Ninja builds, app bundles, ProGuard/R8 rules, signing.
• Debug Java and native crashes (logcat, tombstones, Chromium logs) acro
