We expect you to meet with local teammates two days a week. 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. You may be asked to demonstrate proficiency with AI tools, discuss how you leverage AI, or complete interview exercises without AI assistance. Your Recruiter will provide clear guidance as you move through the interview process. Undisclosed use of AI not previously discussed with or approved by your Recruiter may impact your candidacy. About The Team The International team at Life360 is building the next frontier of meaningful connection — bringing Life360's peace-of-mind platform to families everywhere, regardless of where in the world they live. Our mission is to make the product feel native to every market we enter: localized experiences, regionally relevant features, and the kind of trust that only comes from truly understanding how families in different cultures stay safe, connected, and close. We're expanding Life360's reach beyond its home market so that every family — whether in São Paulo, Berlin, or beyond — has access to the tools that help them navigate the beautiful, chaotic reality of everyday life together. We are a product-minded, AI-Native engineering team. That means AI isn’t just a tool we use — it’s how we work. We’ve redesigned our team workflows around AI, treating it as a first-class collaborator at every stage: ideation, coding, testing, review, and iteration. We ship faster and go deeper because of it, and we’re looking for someone who wants to help define what that looks like at scale. About the Job You'll own the feature layer that makes Life360 feel native to the markets we're expanding into — starting with Brazil and eventually expanding throughout LATAM. That means taking existing Life360 capabilities and adapting them for local reality: safety-first features tailored to how families in Brazil actually live, alternate payment integrations (think carrier billing and local payment rails alongside the app stores), and the UX decisions that make the product feel built in São Paulo, not exported from San Francisco. You'll work directly with the International Features PM and report into the Senior Director of International. The roadmap is early and yours to help shape — you'll be one of the first engineers on the ground, partnering closely with products to define what adaptation actually means market by market. You'll also build and evolve our AI-Native engineering workflows — from how we write code to how we think about team velocity. You'll evolve the standard others follow. Mobile experience is strongly preferred (iOS or Android), though exceptional full-stack engineers are also encouraged to apply. This role is a full-time CLT position, employed through our Employer of Record (EOR) partner in Brazil. AI-Native Expectations We use AI coding tools as a professional standard on this team. Here's what that means in practice: Daily u
