[Remote] Senior Backend Engineer - AI Native Devices Cloud
Note: The job is a remote job and is open to candidates in USA. Life360 is a company dedicated to keeping families connected through innovative technology. As a Senior Backend Engineer on the Devices Cloud team, you will design and deliver core cloud systems that power connected hardware, ensuring scalability, security, and reliability while mentoring junior engineers and collaborating with cross-functional teams.
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
- 3+ 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.)
