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
- Apply AI-native engineering practices day to day: use AI assistants for spec writing, code generation, test coverage, and incident response, and share the prompting strategies that work with the team
- 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
Skills

- 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.)
