Senior Enterprise Security Engineer
About The Position
Life360 is seeking a Senior Enterprise Security Engineer to join their Information Security and Technology team. This role is a technical owner of controls protecting employees, contractors, and devices interacting with Life360 systems, focusing on endpoint, SaaS, identity, and zero trust. The position involves designing, deploying, and operating preventative controls to reduce the attack surface. The engineer will collaborate with IT Engineering, GRC, and the broader security team, co-owning fleet management, device hardening, and endpoint estate health with IT. They will engineer controls and evidence pipelines for compliance with SOC 2, ISO 27001, and privacy requirements, and partner with Detection & Response (D&R) to ensure corporate systems emit necessary telemetry. A key aspect of the role is owning Life360's security awareness program end-to-end and leveraging AI as a force multiplier across all security functions. Life360 is an AI-native company, and the use of AI tools is a professional standard for this team, requiring proficiency in AI for analysis, drafting, automation, and investigations, with a strong emphasis on judgment, accountability, and continuous learning.
Requirements
- 5+ years in security engineering with deep hands-on ownership of endpoint security (Kandji/Intune/Jamf/CrowdStrike), SaaS security, or DLP.
- Hands-on AWS security experience, including IAM policies, CloudTrail. Ability to investigate cloud activity end-to-end and design guardrails.
- Advanced knowledge of operating systems with core competency in two or more of: device hardening (macOS, Windows), SaaS security, DLP, or assurance and validation.
- Experience securing corporate email infrastructure, including SPF, DKIM, DMARC, and anti-phishing controls in Google Workspace or equivalent.
- Experience designing and operating zero trust access controls, including device trust signals, conditional access, and contextual access policies.
- Proven track record driving the implementation of preventative controls.
- Experience managing EDR fleet health at scale, including agent deployment, version currency, policy compliance, and coverage gap remediation (CrowdStrike Falcon preferred).
- Fluent AI user. Daily use of AI tools like Claude, Cursor, Claude Code, or equivalent; understanding of LLM output trustworthiness and limitations; experience shipping production automations or agents.
- Comfortable building with APIs and MCP, not just configuring GUIs.
- Clear, direct communicator who pushes back on risk and drives alignment with IT, Engineering, and leadership.
- Strong collaborator who prioritizes ruthlessly and operates independently under minimal supervision.
- Bias for engineering over ticketing; zero-trust mindset grounded in pragmatism.
- Bachelor’s degree or equivalent.
Nice To Haves
- OSCP, GIAC or equivalent advanced certs.
- Experience building agent-assisted security workflows with MCP servers.
- Experience with DLP tooling.
- Familiarity with compliance frameworks (SOC 2, ISO 27001, NIST CSF).
Responsibilities
- Develop systems and tools that improve the security posture of Life360's DLP, device hardening, SaaS, and zero trust layers.
- Execute security strategy and policy for Life360-built services and SaaS applications.
- Review and provide architectural guidance on infrastructure systems, fleet management, and automation.
- Own EDR agent deployment health and coverage across the endpoint fleet, ensuring CrowdStrike Falcon agents are installed, current, and correctly configured on every managed device; identify and close coverage gaps in partnership with IT and D&R.
- Partner with D&R on log source enablement, ensuring corporate systems (Kandji, Intune, Slack, Box, Google Workspace) emit the telemetry D&R needs for detection and investigation, without owning the detection logic itself.
- Build and operate agent-assisted workflows that take action across endpoint, SaaS, and awareness domains — directing AI more than doing the work by hand, with appropriate guardrails on anything that touches sensitive data or production systems.
- Automate manual toil using Python, Tray.io, Lambda, and AI agents across endpoint, SaaS, and corporate security workflows.
- Engineer controls that satisfy SOC 2 and privacy requirements across device and SaaS layers, partnering with GRC on evidence collection and audit readiness.
- Own the security awareness program end-to-end, including developing and delivering training, running phishing simulations, tracking and reporting metrics, and continuously improving the program to drive measurable behavior change.
