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. 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.
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.
What You’ll Do:
- Conduct security architecture reviews across mobile (iOS/Android), backend (Java, Python, PHP), data pipelines, and third‑party integrations.
- Translate threat models and security requirements into pragmatic guidance engineers can act on.
- Build trusted relationships with product and platform engineering teams.
- Further operationalize and tune ASPM tooling (Cycode) to unify SAST, SCA, secret scanning, and container security into actionable signal, not noise.
- Build security‑as‑code patterns and pre‑approved libraries that make the secure path the default path.
- Automate vulnerability triage, deduplication, and routing so the team spends time on judgment, not toil.
- Drive SLA‑based remediation workflows with clear severity definitions, ownership, and escalation paths.
- Build metrics that translate security posture into language engineering leadership and executives can use.
- Partner on design reviews for AI‑powered features: model access controls, data boundary enforcement, and retrieval system authorization.
- Contribute to securing agent workflows, MCP integrations, and shared AI tooling as adoption scales across engineering.
- Work with Privacy, Legal, and Data Platform on controls for sensitive data: real‑time location, family relationships, and data involving minors.
What We’re Looking For:
- 5+ years in application security, product security, or DevSecOps with a track record of shipping controls that earn adoption, not just approval.
- Hands‑on builder. You define secure patterns, write code, and deliver tooling that holds up in production.
- Experience conducting threat models and security architecture reviews across mobile (iOS/Android), cloud (AWS/GCP), and backend services (Java, Python, PHP).
- Practical experience securing AI/ML systems.
- Working knowledge of ASPM platforms and security tooling: SAST, SCA, secret scanning, container scanning.
- Familiarity with CI/CD security integration.
- Solid grounding in secure development practices: OWASP Top 10, OWASP LLM Top 10, secure‑by‑design principles, and practical remediation guidance.
- Comfort with ambiguity.
- Strong cross‑functional communication.
Nice to Have:
- Experience with multi‑agent orchestration frameworks and their identity and authorization challenges.
- Background in consumer technology or privacy‑sensitive domains.
- Experience securing location‑based services or products involving data from minors.
- CISSP, OSCP, GWAPT, or similar certifications.
- Contributions to open‑source security tools, public research, or conference speaking.
