[Hiring] Senior Product Security Engineer @Life360

Role Description

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.

What You’ll Do

• Security Partner Engagement
  • 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.
• Tooling & Secure Defaults
  • 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.
• Vulnerability Management
  • 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.
• AI & Emerging Platform Security
  • 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.

Qualifications

• 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, including prompt pipelines and model access controls.
• 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, secure-by-design principles.
• Comfort with ambiguity and energized by first-draft standards.
• Strong cross-functional communication skills.

Nice to Have

• Experience with multi-agent orchestration frameworks.
• 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 or public research.

Benefits

• Competitive pay and benefits.
• Medical, dental, vision, life and disability insurance plans (100% paid for employees).
• 401(k) plan with company matching program.
• Mental Wellness Program & Employee Assistance Program (EAP).
• Flexible PTO, 13 company-wide days off throughout the year.
• Winter and Summer Weeklong Synchronized Company Shutdowns.
• Learning & Development programs.
• Equipment, tools, and reimbursement support for a productive remote environment.
• Free Life360 Platinum Membership for your preferred circle.
• Free Tile Products.
