Life360 has more than 500 (and growing!) remote-first employees. For more information, please visit life360.com . Life360 is a Remote-First company, which means a remote work environment will be the primary experience for all employees. All positions, unless otherwise specified, can be performed remotely (within the US) regardless of any specified location above. 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. The threat surface is expanding. The compliance frameworks are catching up. The people on this team aren't waiting for either. About the Job As a Senior Enterprise Security Engineer, you'll be a technical owner of the controls that protect every employee, contractor, and device interacting with Life360 systems — endpoint, SaaS, identity, and zero trust. This is a builder role: you design, deploy, and operate the preventative controls that reduce the attack surface before anything reaches Detection & Response. You'll partner closely with IT Engineering, GRC, and the broader security team. With IT, you'll co-own fleet management, device hardening, and the day-to-day health of the endpoint estate. With GRC, you'll engineer controls and evidence pipelines that satisfy SOC 2, ISO 27001, and privacy requirements. With D&R, you'll own the telemetry side of the partnership — making sure corporate systems (Kandji, Intune, Slack, Box, Google Workspace, Okta) emit what they need for detection, without owning the detection logic or incident response yourself. You'll also own Life360's security awareness program end-to-end, and you'll use AI as a force multiplier across all of it — directing agent-assisted workflows for endpoint, SaaS, and awareness work, with appropriate guardrails on anything touching sensitive data or production. We're at an inflection point. Life360 is deploying agentic systems into how we build and operate, and the security and governance implications are still being worked out — by us, and by the industry. We're not waiting. 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, agents with production access, and privileged identity changes all need careful guardrails — and you can articulate where AI helps, where it hurts, and where it needs a human in the loop. Leverage: When AI is working well, you take on problems that would otherwise require a larger team. We hire people who use that leverage to ship better outcomes, not just faster ones. Continuous learning: The tooling moves fast. You stay current, share what works with the team, and speak up when something would meaningfully change how we operate. The US-based salary range for this position is $152,000 to $224,000. We take into consideration an individual's background and experience in determining final salary - therefore, base pay offered may vary considerably depending on geographic location, job-related knowledge, skills, and experience. The compensation package includes a wide range of medical, dental, vision, financial, and other benefits, as well as equity.
