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 Circle Expansion team at Life360 is building the next frontier of meaningful connection — deepening Life360’s peace-of-mind platform beyond the core family circle: aging parents staying safely independent, pre-teens navigating the world with wearables, and extended families and loved ones living apart. Our mission is to unlock more value for these members and the families around them, with features that help people stay safe, connected, and sane amidst the chaos of everyday family life. 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 Life360 is hiring an AI-Native Engineer — a senior full-stack engineer who doesn’t just use AI tools, but thinks natively in them. You’ll be central to how the Circle Expansion team builds product, where AI has reshaped how the entire team designs, builds, and ships. You’ll design and build features that serve some of our most important and fastest-growing member segments: aging parents who want to stay safely connected with their families, pre-teens with wearables taking their first steps toward independence, sports teams that need real-time coordination, and school communities simplifying carpool logistics. You’ll build and evolve our modern AI-Native engineering workflows — from how we write code, to how we run standups, 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 or backend engineers are also encouraged to apply. For candidates based in the US, the salary range for this position is $148,000 to $216,000 USD. For candidates based out of Canada, the salary range for this position is 171,500 to 201,000 CAD.
