Sr. Staff Backend Engineer AI-Native, Devices Cloud

About Life360 Life360's mission is to keep people close to the ones they love. Our category-leading mobile app and Tile tracking devices empower members to protect the people, pets, and things they care about most with a range of services, including location sharing, safe driver reports, and crash detection with emergency dispatch. Life360 serves approximately 91.6 million monthly active users (MAU) across more than 180 countries. Life360 is a Remote First company. All positions, unless otherwise specified, can be performed remotely (within the US and Canada). About the Devices Cloud Team The Devices Cloud team owns the backend services that power Life360's fleet of connected hardware — Tile trackers, Jiobit wearables, Pet GPS trackers, and emerging device categories. We manage real-time device state, high-frequency telemetry ingest, and the cloud infrastructure that translates physical-world signals into reliable, family-facing experiences. Our work sits at the intersection of hardware, firmware, mobile, and platform — and runs at a scale where correctness and reliability aren't optional. We are an AI-Native team. AI isn't an add-on to how we work — it's how we work. We've redesigned our development workflows around AI, using it as a first-class collaborator at every stage: spec writing, code generation, test authoring, incident triage, and system design. We ship faster and go deeper because of it. We're looking for engineers who want to help define what AI-native backend development looks like for complex, hardware-connected systems. About the Job As a Sr. Staff Cloud Engineer on the Devices Cloud team, you will own the technical direction of the cloud systems that power Life360's connected hardware — Tile trackers, Jiobit wearables, and emerging device categories. This is a systems-level leadership role: you are the recognized technical authority for our device cloud infrastructure, spanning real-time state management, high-frequency telemetry ingest, and the integration layer that connects physical hardware to family-facing experiences. At this level, your work extends well beyond implementation. You set technical direction, define architectural standards, mentor Staff and Senior engineers, and partner with engineering and product leadership to align the technical roadmap with company goals. You operate across teams and functional groups — influencing firmware, mobile, platform, and data teams — and your decisions shape systems serving tens of millions of families daily. You are also a leader in AI-native engineering. You don't just use AI — you define how it should be used. You architect agent-driven workflows, codify practices that multiply team output, and partner with engineering leadership to spread these patterns across the broader organization. For candidates based in the US, the salary range for this position is $216,500 to $318,500 USD. For candidates based out of Canada, the salary range is 251,000 to $295,000 CAD. Note: 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 Own the technical architecture and long-term roadmap for Devices Cloud systems — device connectivity, telemetry ingest, state management, command/control, and data pipelines — ensuring they are scalable, secure, and resilient at Life360's scale. Define and drive system-level technical direction across multiple teams, identifying architectural trade-offs, resolving cross-team design conflicts, and aligning engineering efforts with company strategy.
