Requirements
• 5+ years of experience building and operating backend or cloud infrastructure systems, ideally including some IoT, telematics, or hardware-adjacent work. • Track record of owning complete features and subsystems, contributing to technical design, and leading medium-sized projects to delivery. • Strong experience with cloud-native infrastructure (AWS: EKS, Lambda, DynamoDB, SQS, Kinesis, etc.), distributed systems, and data pipelines. • Hands-on experience using AI coding assistants for substantive engineering work, with the judgment to review and own everything you ship. • Experience mentoring junior engineers and helping raise team-wide engineering standards. • Strong communication skills: able to explain technical concepts clearly to peers, partner teams, and managers. • Comfortable navigating ambiguity and managing competing priorities within and across teams. • Experience with high-frequency ingest systems, time-series data, and streaming platforms (Kafka, Kinesis, or similar). • Bachelor’s Degree in a Technical field, or equivalent experience. • Experience with IoT, telematics, embedded, or firmware-adjacent systems. • Background in SRE practices, reliability engineering, and progressive delivery. • Familiarity with observability platforms (Prometheus, Grafana, OpenTelemetry, DataDog). • Experience contributing to industry conversations: open-source projects, conference talks, or technical publications. • Knowledge of hardware/firmware communication protocols (MQTT, BLE, CoAP, etc.). • 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. • Daily use: • Judgment and ownership: AI-generated code gets the same review you'd give any PR. You are accountable for everything you ship. • Judgment and ownership: • 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. • Velocity: • 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. • Team leadership: • Continuous learning: The tooling is changing fast. You stay current and bring recommendations to the team when something would meaningfully improve how we work. • Continuous learning:
Responsibilities
• Design, build, and operate Devices Cloud services — device connectivity, telemetry ingest, state management, command/control, and data pipelines — ensuring they are scalable, secure, and reliable at Life360's scale. • Own complete features and subsystems from technical design through production, breaking down complex work, identifying dependencies, and delivering accurate estimates. • Partner with firmware, mobile, product, and platform teams to define APIs and integration patterns that translate cleanly across the hardware-software boundary. • Lead medium-sized, cross-functional initiatives, coordinating the work of other engineers and keeping delivery on track. • Identify risks, bottlenecks, and security gaps in your areas of ownership, and build in the automation and tests that prevent regressions. • Mentor junior engineers: coach them on structuring changes for review, conduct thorough code reviews, and help grow their skills. • Communicate progress, trade-offs, and technical concepts clearly to peers, partner teams, and your manager. • Write clear, concise technical specifications, and contribute to team documentation and knowledge sharing. • Participate in on-call rotation and contribute to high-severity incident response and post-mortems.
Benefits
