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 Information Security and Technology team is responsible for keeping Life360 safe — our systems, our employees, and the tens of millions of families who trust us with their location data. That obligation is the starting point. How we meet it is what makes this team different. We are builders. Security controls that don't get used aren't controls. Compliance programs that create friction without reducing risk aren't programs. We build things that work in production, earn adoption from engineering teams, and get better over time — and we use AI to do it at a scale a traditional team couldn't. We're also at an inflection point. Life360 is deploying agentic systems into how we build and operate, and the security and governance implications of that are still being worked out — by us, and by the industry.

About the Job Product Security at Life360 sits at the intersection of a consumer platform trusted by nearly 100 million families and an engineering organization moving fast into AI-native development. This role is engaged across product and platform teams as a security partner, not a gate. You'll conduct design reviews, build secure defaults, drive vulnerability management, and help shape how we ship safely across mobile, backend, data pipelines, and an expanding surface of AI-powered features. We use AI tools as a professional standard on this team. That means daily use for real work, full ownership of what you ship, and the judgment to know where AI helps and where it needs guardrails. You'll bring that same lens to the products you secure: frontier model integrations, agentic workflows, and sensitive data pipelines handling real-time location and family data. We use AI tools as a professional standard on this team. Here's what that means in practice. Ai-Native Daily use: You use AI tools for real, substantive work — analysis, drafting, automation, code, investigations, evidence gathering. Judgment and ownership: AI-generated work gets the same scrutiny you'd give any human-produced artifact. You're accountable for everything you ship. Domain-specific judgment: You know where AI is the wrong tool. Sensitive data handling, attacker-controlled inputs, a
