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 Platform Foundations is part of Life360's Developer Experience Group (DevX) — the AI platform layer powering how engineers build, test, and ship at Life360. We own the foundational infrastructure that makes the entire development lifecycle faster, safer, and more intelligent. We're a small team with outsized impact, building the systems other engineers depend on every day — and we're doing it with an AI-native mindset from the ground up. We're building the systems, platforms, and intelligence that power the entire software delivery lifecycle. Our work spans continuous testing infrastructure, self-healing test systems, AI-native developer tooling, agentic quality automation, and the observability pipelines that keep Life360's engineering engine running at scale. We partner closely with Mobile, Backend, and Release Engineering teams — and our output directly shapes the speed, confidence, and quality with which Life360 ships to millions of families around the world. We move fast, think in systems, and care deeply about craft. You'll have high autonomy, real ownership, and the opportunity to define what AI-native engineering infrastructure looks like — not just at Life360, but as a model for the industry. About the Job This role is not about writing software. It is about producing software — at a level of quality, speed, and scope that would previously have required a much larger team. Our group is the AI platform layer that powers how engineers build, test, and ship across Life360's mobile and cloud products. Platform Foundations — the team you'd be joining — owns the foundational infrastructure that makes the entire development lifecycle faster, safer, and more intelligent. We're looking for a Mobile Engineer who has strong iOS and/or Android engineering roots, but whose center of gravity has shifted: you think in systems, you direct AI to produce outcomes, and you're energized by the idea of rebuilding how mobile software gets made, tested, and validated — from the ground up. This role sits at the intersection of mobile engineering, platform infrastructure, and applied AI. You'll help us move Life360 toward a fully AI-native product development lifecycle (PDLC) — one where continuous testing, self-healing systems, and agentic workflows are the default, not the exce
