About The Team

The Infrastructure Team is a small, high-leverage team with a large footprint - supporting over 200 backend services running on Kubernetes clusters with 40,000+ cores, processing 70B+ requests per day at the edge, and handling 200B+ internal messages daily. We run the platforms that every engineering team at Life360 depends on, including AWS, Kubernetes, ArgoCD, Jenkins, HAProxy, Cloudflare, and more.

Because of our scale and team size, we lean heavily on AI to multiply what a small team can do - from autonomous incident response workflows to AI-powered infrastructure scripting and self-healing platform automation. This isn't AI as a productivity add-on; it's AI as how we build. Engineers joining this team will contribute directly to agentic systems that operate our infrastructure with less toil and more intelligence.
About the Job

Life360 is hiring an AI-Native Site Reliability Engineer - a senior engineer who doesn't just use AI tools, but thinks natively in them. You'll be central to how the Infrastructure team builds its products, develops its services and tools, and how we use AI for scaling our infrastructure in the future.

As a Senior Site Reliable Engineer II - Infrastructure (AI Native), you will help build and maintain the infrastructure platforms that over 200 backend services run on. You will be responsible for solving complex problems and designing and building scalable and resilient Platform Infrastructure to support services that run on Kubernetes clusters with over 40,000 cores, receive over 70Bn requests per day at the edge, process ~200B messages per day internally, and have databases that process over 200k queries per second. You are comfortable exposing compute, data stores, and messaging as Platform as a Service to Life360 Cloud teams.

The Canada-based salary range for this position is 163,000 CAD to 194,000 CAD. We take into consideration an individual's background and experience in determining final salary; therefore, base pay offered may vary considerably depending on geographic location, job-related knowledge, skills, and experience. The compensation package includes a wide range of medical, dental, vision, financial, and other benefits, as well as equity.
What You'll Do

As a Senior Site Reliable Engineer II - Infrastructure (AI Native), you will be responsible for

• Scaling and maintaining our infrastructure and services using AI (Claude Code) as a first-class collaborator in your daily development workflow.
• Being opinionated on technical direction and strategy (and documenting those opinions for others to be able to follow).
• Leading and mentoring other engineers on the team
• Owning and resolving the most complex infrastructure failures - Kubernetes scheduling edge cases, networking degradation, cross-service cascading failures, and AWS platform issues that other engineers escalate
• Participating in a shared on-call rotation (roughly one week every six to eight weeks on call)
• Estimating schedules, breaking tasks down to reasonable 1-3 day tasks.
• Driving cloud cost efficiency by identifying over-provisioned resources, rightsizing EC2 and container workloads, and building tooling to surface cost anomalies before they compound

What We're Looking For

• Bachelor's in Computer Science, Engineering, related field, or equivalent practical experience
• Expert-level experience (5+ years) managing medium to large-scale deployments on AWS (~5000 instances, 50+ accounts), or equivalent.
• 3+ years of experience programming in Java, Python, or other formal programming languages
• Strong Kubernetes experience (3+ years) deploying and managing at scale (100s of Deployments,10k+ containers, 20k+ Cores).
  • Understanding of container orchestration and microservices
  • Experience with service discovery/service mesh
• Strong Linux administration experience, shell/bash scripting.
• Expert-level experience with Infrastructure as code tools: Terraform, CloudFormation; config management/provisioning tools: Ansible, Chef, etc.
• Strong Build / Automation / CI/CD experience.
• Strong Knowledge/experience with networking and load-balancer technologies.
• Experience with existing open-source projects such as Consul, Docker, ArgoCD, Nexus, Jenkins
• Experience with large-scale Kafka deployments
• Database knowledge is a plus.
• Excellent troubleshooting skills, expertise with any monitoring tools, and attention to detail
• Excellent interpersonal skills and highly collaborative working style
• Hands-on experience with AI coding tools (Claude Code, Cursor, or equivalent) used for infrastructure scripting, incident response automation, or tooling development

We value having a diverse and inclusive community from many backgrounds, so even if you don't meet 100% of the above qualifications, you should still seriously consider applying!
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.
• Agentic thinking: We are actively building multi-agent systems that automate operational work - from incident response pipelines to infrastructure remediation. You don't need to have built a production agentic system, but you should be curious about this space, have opinions on where it works and where it breaks, and be ready to contribute to it.
• 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.
• Continuous learning: The tooling is changing fast. You stay current and bring recommendations to the team.

Our Benefits

• Competitive pay and benefits

• Winter and Summer Week-long Synchronized Company Shutdowns
• Learning & Development programs
• Equipment, tools, and reimbursement support for a productive remote environment
• Free Life360 Platinum Membership for your preferred circle
