Principal Agentic Engineer, AI Ecosystem
Life360 · Remote, USA
About this role
**About Life360** Life360’s mission is to keep people close to the ones they love. Our category-leading mobile app, Tile tracking devices, and Pet GPS tracker help members protect the people, pets, and things they care about most—through location sharing, safe driver reports, and crash detection with emergency dispatch. Life360 serves ~107.7M monthly active users (MAU) across 180+ countries. **Remote-First** Life360 is remote-first. Unless otherwise specified, roles can be performed remotely within the US. **We are AI Native** AI is integral to how we build and operate. During interviews, AI tool usage varies by role. You may be asked to demonstrate proficiency with AI tools, discuss how you leverage AI, or complete interview exercises with/without AI assistance. Undisclosed AI use not previously discussed with or approved by your Recruiter may impact your candidacy. --- ## About the Team Life360’s AI ecosystem is built by three teams working toward a shared 2027 vision: - **AI Platforms**: foundational infrastructure and governance (gateways/MCP connector infra, cost controls, observability & safety guardrails, agent deployment/orchestration, knowledge graphs) - **AI Dev Tooling (AI DevX)**: AI-powered developer tools across the SDLC (coding assistance, automated/agentic testing, shared primitives like CLAUDE.md and evals) - **Agentic PDLC**: agents that remove humans from repetitive product-development work (on-call investigation, bug triage, code review, release), consolidated under one owner There’s also an intentional “shared middle ground” of foundational questions (e.g., non-human identity & agent authZ, model regression eval frameworks, workflow/agent eval infrastructure, atomic agent-unit definitions, and standards for what an agent can never do). --- ## About the Job — Principal Agentic Engineer, AI Ecosystem Life360 is hiring a **Principal-level Agentic Engineer** to hold the system view across **AI Platforms**, **AI DevX**, and **Agentic PDLC**, and to own the unowned middle ground between them. This is **not** a coordination role. You’ll have **clear, end-to-end ownership** of a defined set of cross-cutting problems—an **architecture-and-build** position where you: - Define what an **“agent”** is as a reusable unit at Life360 - Set standards to make agents **safe and evaluable** - Build an ecosystem that supports agents - Help teams build to that architecture - Craft the vision for how the agent ecosystem evolves **Two altitudes (must be strong at both):** - **Strategic**: set the technical vision for the AI-native developer ecosystem so teams build against shared primitives - **Tactical**: hands-on work in core components (execution frameworks, context/retrieval, eval harnesses, identity/authZ for unattended agents) and ship foundational pieces You’ll partner closely with the three teams and Product leadership, but you won’t report through any single one—your mandate is the **seams** between them. **Compensation (US)** - Salary range: **$247,000–$363,000** (based on background, knowledge, skills, and experience; may vary by geographic tier) - Total compensation includes **RSUs** and a comprehensive benefits package --- ## What You’ll Do ### Architect across the ecosystem - Hold the system view across AI Platforms, AI DevX, and Agentic PDLC so investments compose instead of collide - Drive build-vs-buy decisions for PDLC-critical agents and ecosystem-wide capabilities - Build agent-supporting ecosystem capabil
