About The Position

Life360 is seeking a Senior Product Security Engineer to join their Information Security and Technology team. This role will partner with product and platform teams to ensure the security of consumer-facing products and an AI-native development environment. The engineer will conduct design reviews, build secure defaults, manage vulnerabilities, and contribute to securing mobile, backend, data pipelines, and AI-powered features. The position emphasizes a hands-on, builder mentality, leveraging AI tools as a professional standard and applying this lens to securing frontier model integrations, agentic workflows, and sensitive data pipelines. The role requires a strong understanding of application security principles and the ability to translate technical security concepts into actionable guidance for engineering teams.

Requirements

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. You're a practitioner, not just an advisor.
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. You've worked with prompt pipelines, RAG architectures, model access controls, or agentic workflows and understand the trust, authorization, and data boundary problems they introduce.
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. You're energized by first-draft standards, testing approaches, and scaling what works rather than waiting for a playbook.
Strong cross-functional communication. You carry risk, tradeoffs, and technical decisions across engineering, product, and leadership without losing precision. You can reshape a risky decision clearly and constructively.

Nice To Haves

Experience with multi-agent orchestration frameworks and their identity and authorization challenges.
Background in consumer technology or privacy-sensitive domains where personal data is a core product obligation, not just a legal checkbox.
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.

Responsibilities

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.
