We are AI Native We are building an AI native company where AI is an integral part of how we build and operate. AI tool usage during interviews varies by role.

About The Team The On App Ads Engineering team owns the ads layer inside the Life360 app, which reaches approximately 102.4 million monthly active users. We build and maintain the SDK, header-bidding and mediation integrations, ad quality, and consent behind every ad on iOS and Android, serving 300M+ ad requests a day. We also own the testing and monitoring that keep that stack reliable, so every impression is competitively priced, respects each member’s privacy choices, and renders safely. We guide the direction of our future advertising experience by introducing new formats, placements, and capabilities that grow revenue while protecting the member experience.
