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.
About The Team
The Infrastructure Team is a small, high-leverage team with a large footprint — supporting over 200 backend services running on Kubernetes clusters with 40,000+ cores, processing 70B+ requests per day at the edge, and handling 200B+ internal messages daily. We run the platforms that every engineering team at Life360 depends on, including AWS, Kubernetes, ArgoCD, Jenkins, HAProxy, Cloudflare, and more.
Because of our scale and team size, we lean heavily on AI to multiply what a small team can do — from autonomous incident response workflows to AI-powered infrastructure scripting and self-healing platform automation. This isn’t AI as a productivity add-on; it’s AI as how we build. Engineers joining this team will contribute directly to agentic systems that operate our infrastructure with less toil and more intelligence.
About the Job
Life360 is hiring an AI-Native Site Reliability Engineer — a senior engineer who doesn’t just use AI tools, but thinks natively in them. You’ll be central to how the Infrastructure team builds its products, develops its services and tools, and how we use AI for scaling our infrastructure in the future.
As a Senior Site Reliable Engineer II - Infrastructure (AI Native), you will help build and maintain the infrastructure platforms that over 200 backend services run on. You will be responsible for solving complex problems and designing and building scalable and resilient Platform Infrastructure to support services that run on Kubernetes clusters with over 40,000 cores, receive over 70Bn requests per day at the edge, process ~200B messages per day internally, and have databases that process over 200k queries per second. You are comfortable exposing compute, data stores, and messaging as Platform as a Service to Life360 Cloud teams.
