About the role

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.
How we meet it is what makes this team different.
Security controls that don't get used aren't controls.

Own the security strategy for frontier model access and MCP governance.
Set the direction that builders implement within
Define our approach to prompt injection defense, adversarial input handling, and behavioral monitoring patterns and establish the detection philosophy, telemetry requirements, and response framework the team builds and operates within.
Lead design reviews and build the access controls, data boundary enforcement, and abuse detection that keep a shared AI environment safe across an employee population with varying privilege levels.
Build AI supply chain integrity into the platform. Develop model provenance practices, service vetting, and dependency controls that keep the AI stack trustworthy as it grows.
15+ years in security engineering with depth in application security, cloud security, IAM, or detection. A track record of building controls that earn adoption, not just approval.
Deep grounding in IAM for non-human systems: service identities, OAuth, secrets management, RBAC/ABAC, and least-privilege architecture at scale. You've designed and built identity systems, not just consumed them
Comfort with ambiguity and in-flight builds. You're energized by figuring things out, writing first-draft standards, testing approaches, and scaling what works.
Our company's mission-driven culture is guided by our shared values to create a trusted work environment where you can bring your authentic self to work and make a positive difference.

15+ years in security engineering with depth in application security, cloud security, IAM, or detection.
Experience with production telemetry and detection at an architectural level.
Familiarity with NIST AI RMF, OWASP LLM Top 10, and adjacent compliance environments for consumer data at scale.
Bachelor's degree or equivalent experience in Computer Science, Information Security, or a related field.
Experience designing or reviewing security for internal enterprise AI platforms serving non-technical users.

Experience with frontier model API security, tool-use authorization patterns, or access governance for AI systems at scale.
Hands-on experience with multi-agent orchestration frameworks (LangGraph, AutoGen, CrewAI, or similar) and their trust, identity, and authorization challenges.
Familiarity with knowledge graph architectures, vector stores, or RAG systems - and the access control and data boundary problems they introduce.

Competitive pay and benefits
Medical, dental, vision, life and disability insurance plans (100% paid for employees)
Mental Wellness Program & Employee Assistance Program (EAP) for mental well-being
Flexible PTO, 13 company-wide days off throughout the year
Learning & Development programs
Equipment, tools, and reimbursement support for a productive remote environment

That obligation is the starting point.
We are builders.
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 people on this team aren't waiting for either.
