#### We are AI Native
We are building an AI native company where AI is an integral part of how we build and operate. AI tool usage during interviews varies by role. You may be asked to demonstrate proficiency with AI tools, discuss how you leverage AI, or complete interview exercises without AI assistance. Your Recruiter will provide clear guidance as you move through the interview process.
Undisclosed use of AI not previously discussed with or approved by your Recruiter may impact your candidacy.
### About The Team
The AI Platforms team builds the shared foundation that lets Life360 use AI quickly and safely: model access and routing, MCP gateway and connectors, the agent runtime and orchestration platform, memory and knowledge infrastructure, evals and observability, and cost controls. We work alongside AI Dev Tooling and Agentic PDLC, the teams reshaping how Life360 builds with agents, and we're extending the same foundations to power AI features for our members.
### About the Job
The AI Platforms team at Life360 builds the shared foundation that enables the rapid and safe use of AI across the organization. This includes model access and routing, the MCP gateway and connectors, the agent runtime and orchestration platform, memory and knowledge infrastructure, evaluations and observability, as well as cost controls. As an AI Platform Engineer, you will play a crucial role in developing the infrastructure that supports every engineer and agent at Life360, extending it from internal productivity to member-facing product features.
In this role, you will own production components end to end, setting the technical direction for your area and transforming early momentum into established pathways that other teams will adopt. You are a builder at heart, responsible for shipping code, reviewing designs, and making pragmatic build-vs-buy decisions as the model and tooling landscape evolves. You will collaborate closely with the AI Dev Tooling and Agentic PDLC teams, which are reshaping how Life360 builds with agents, while also extending the same foundational capabilities to power AI features for our members. You will report to the Director of AI Platforms.
*The US-based salary range for this position is $149,000 to $271,500 USD. We take into consideration an individual's background, job-related knowledge, skills, and experience in determining final salary. Base pay may also vary based on geographic location, with US work locations falling into one of three geographic tiers.*
*Total compensation is inclusive of equity compensation in the form of* Restricted Stock Units (RSUs), as well as a comprehensive benefits package, including medical, dental, vision, financial, and other benefits.
### What You’ll Do
- Establish the overarching vision and paved paths that enable teams across Life360 to adopt AI-native engineering best practices
- Build the agent runtime and orchestration platform, including identity, authorization, and audit for scheduled and unattended agents
- Operate the MCP gateway and connector infrastructure: secure brokering so agents reach internal data, APIs, repos, and SaaS tools through managed, auditable connections rather than unmanaged direct access
- Support the LLM gateway: model access and routing, authentication, rate limits, token budgets, and per-team cost attribution
- Build eval and regression infrastructure: golden datasets, offline evals, CI hooks, and result storage, with quality regression treated as a first-class alert
- Setup observability: prompt and response tracing, cost per request, quality signals, and drift detection
- Work with Security, Privacy, and Legal to build data handling, tenant isolation, and auditability into the platform from day one
- Define how product teams access, run, and monitor AI inference in production at member scale: serving, latency, reliability, and provider management
- Own what you build in production: SLOs, dashboards, deployment pipelines, and incident response
- Enable memory, retrieval, and knowledge infrastructure that agents can share
- Make the right way the easy way: SDKs, templates, reusable skills, docs, and internal champions that engineers and their agents choose to use
- Partner with AI DevX and Agentic PDLC to turn their needs into shared primitives instead of one-off builds
- Mentor engineers on agent architecture and evaluation rigor, and write design docs and standards other teams can build against
- Explore foundational memory, retrieval, and shared knowledge capabilities for agents as longer-term platform needs evolve
### What We’re Looking For
- 8+ years of engineering experience, including 3+ years building platforms or infrastructure used by other engineers
- Experience building and operating production AI systems, such as agentic workflows, LLM integrations, retrieval, and evaluation
- Working knowledge of MCP and agent orchestration, including how agents connect to internal systems with appropriate controls
- Strong backend and cloud fundamentals: distributed systems, APIs, infrastructure as code, and reliability and observability practices
- Experience running AI inference in production, including latency, reliability, provider management, and cost tradeoffs
- Sound judgment on what deserves a shared platform investment and what doesn't
- Clear written communication: design docs and standards precise enough for other engineers (and their agents) to build against
#### Bonus Experience
- Experience with non-human identity, service-account, or agent authZ models
- Experience building or operating an agent orchestration or deployment platform, or an MCP-style connector gateway
- Familiarity with SOC 2, GDPR, or similar compliance frameworks
- Background in ML infrastructure or model observability
- Experience with consumer-scale products or privacy-sensitive data
#### AI-Native Expectations
We use AI coding tools as a professional standard on this team. Here's what that means in practice:
- Daily use: You use AI coding assistants (we support Claude Code, Cursor, and GitHub Copilot) for real, substantive tasks: analysis, coding, refactoring, testing, navigating codebases, and documentation. Not just research or autocomplete.
- Judgment and ownership: AI-generated code gets the same review you'd give any PR. You are accountable for everything you ship.
- Velocity: We expect senior engineers who use AI well to operate with meaningful leverage — doing more with the same time, taking on problems that would otherwise require a larger team.
- Team leadership: You share what works. You automate prompting strategies that others can build on and help teammates earlier in their AI workflow adoption get up to speed.
- Continuous learning: The tooling is changing fast. You stay current and bring recommendations to the team when something would meaningfully improve how we work.
### Our Benefits
- Medical, dental, vision, life and disability insurance plans (100% paid for employees)
- Paid parental leave
- 401(k) plan with company matching program
- Mental Wellness Program & Employee Assistance Program (EAP) for mental well-being
- Generous time off: flexible PTO, companywide holidays throughout the year plus summer and winter shutdowns
- Learning & Development programs
- Equipment, tools, and reimbursement support for a productive remote environment
- Free Life360 Platinum Membership and Tile trackers
AI Usage: We use AI to help make our hiring process efficient. That said, every hiring decision is made by real Life360 hiring teams
### Life360 Values
Our company’s mission-driven culture is guided by our shared values to create a trusted work environment where you can bring your authentic self to work and make a positive difference
- Be a Good Person - We have a team of high integrity people you can trust.
