Senior Software Engineer II, AI-Native - Location Platform

About the role

The Location Platform team is the engine behind Life360. We own the core infrastructure that collects, processes, and delivers location data to every product experience across the company - from real-time family location sharing to crash detection and safe driving reports. Our systems serve tens of millions of active users across 180+ countries, processing billions of location updates daily. We operate as a true platform organization: our customers are the product teams that build on top of our data and services. We care deeply about reliability, accuracy, latency, and battery efficiency - the invisible qualities that make Life360 feel like magic to the families who depend on it. 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. You'll design and build the mobile location infrastructure that runs on tens of millions of devices worldwide - the on-device systems responsible for collecting, filtering, and delivering accurate location data while respecting battery life and OS constraints. You'll build and evolve our modern AI-Native engineering workflows - from how we write code, to how we run the development process, 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. This role is a full-time CLT position, employed through our Employer of Record (EOR) partner in Brazil.
