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 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 Senior Backend Engineer on the Devices Cloud team, you will design and deliver the core cloud systems that power Life360's connected hardware — Tile trackers, Jiobit wearables, and emerging device categories. You own complete features and subsystems across real-time state management, high-frequency telemetry ingest, and the integration layer that connects physical hardware to family-facing experiences.

You operate with a high degree of autonomy. You participate in technical design, break down complex work, deliver accurate estimates, and lead medium-sized projects end to end. You partner closely with firmware, mobile, platform, and data teams, mentor junior engineers, and help raise the team's engineering standards. Your work shapes systems serving tens of millions of families daily.

You are also a strong practitioner of AI-native engineering. You use AI as a first-class collaborator across spec writing, coding, testing, and incident triage — and you share the practices that work so the whole team moves faster.

For candidates based in the US, the salary range for this position is $148,000 - $216,500 USD. For candidates based out of Canada, the salary range is not mentioned.
