[Hiring] Senior Backend Cloud Developer II, Developer Experience @Life360

Role Description

You’ll join a team that values autonomy, high craft, and direct impact on every engineer at Life360. As a Senior Developer II on the Cloud Success team, you’ll work at the intersection of cloud infrastructure and internal platform engineering. You’ll design, build, and evolve systems that improve the reliability, scalability, and developer experience of our internal platform — from CI/CD pipelines to Kubernetes tooling to AI-powered developer agents. This is a hands-on role: you’ll balance deep technical execution with cross-team collaboration, directly shaping how engineers across Life360 build and ship software. You’ll be a key contributor to our AI-native engineering transformation, building automation that accelerates the pace of development across the entire engineering org.

What You’ll Do

• Design and implement CI/CD pipeline infrastructure using GitHub Actions, Argo Rollouts, or similar tools, optimizing for developer velocity and reliability.
• Build and maintain internal developer tooling, SDKs, and self-service platform capabilities on top of Kubernetes (EKS) and GitOps workflows (ArgoCD).
• Own infrastructure-as-code (Terraform/Atmos) for shared developer platform resources across multiple AWS accounts.
• Work with developers and operations engineers to define clear, helpful guidelines for rolling production changes out safely.
• Track metrics on organization tools like Cortex to validate that our changes are having the intended effect.
• Mentor junior and mid-level engineers on cloud-native development, platform patterns, and AI engineering practices.
• Contribute to incident response and postmortem processes, including building AI-driven tooling for detection, triage, and prevention.

Qualifications

• 5+ years in software or platform engineering, with at least 2 years in infrastructure- or tooling-focused roles.
• Strong experience with Kubernetes (EKS preferred), Helm, and GitOps workflows (ArgoCD).
• Proficiency designing and operating CI/CD pipelines (GitHub Actions, Harness, CodeFresh, or similar).
• Hands-on experience with infrastructure-as-code (Terraform, Atmos).
• Solid understanding of AWS services, networking, IAM, and distributed system patterns.
• Strong programming skills in Go, Python, or Java, with demonstrated ability to ship production-grade internal tooling.
• Fluent AI-native engineer: uses Claude Code, Copilot, or similar agents daily; has built or deployed at least one AI-powered automation in a production context.
• Proven ability to drive cross-team platform initiatives and communicate technical tradeoffs to non-technical stakeholders.
