Requirements
• 12+ years of experience designing and operating large-scale backend or cloud infrastructure systems — with a strong preference for IoT, telematics, or hardware-adjacent domains. • Demonstrated track record of setting technical direction across teams, driving architectural decisions, and aligning engineering roadmaps with business goals. • Deep expertise with cloud-native infrastructure (AWS: EKS, Lambda, DynamoDB, SQS, Kinesis, etc.), distributed systems design, and high-throughput data pipelines. • Strong hands-on experience with agentic AI workflows — not just prompt engineering, but architecting multi-agent systems, managing context, and building AI-native development practices at a team or org level. • Proven ability to mentor Staff and Senior engineers, elevate team-wide engineering standards, and drive cultural change through influence rather than authority. • Exceptional communication skills: able to distill complex architectural concepts for diverse audiences, from junior engineers to executive leadership. • Ability to navigate ambiguity, manage competing priorities across groups, and lead through influence in a cross-functional environment. • 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. • Nice-to-Have • Nice-to-Have • 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
• 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. • Lead AI-native engineering practices for Devices Cloud: architect agentic workflows, codify patterns for AI-assisted spec writing, code generation, test coverage, and incident response — and partner with org leadership to extend these playbooks broadly. • Partner with firmware, mobile, product, and platform teams to define APIs, integration standards, and device-driven workflows that translate cleanly across the hardware-software boundary. • Drive the architecture and delivery of large-scale, cross-team initiatives — from conception through production — managing dependencies, unblocking teams, and maintaining accountability for outcomes. • Anticipate system bottlenecks, failure modes, and security risks before they materialize; define safeguards and engineering standards that prevent class-of-problem recurrences. • Mentor and grow Staff and Senior engineers across the team: provide architectural guidance, conduct high-quality technical reviews, and act as a force multiplier for team output. • Collaborate with engineering and product leadership to influence organizational priorities, advocate for technical investments, and communicate technical strategy to executive stakeholders. • Represent the team in cross-functional forums; produce clear, concise architectural documentation and roadmap artifacts accessible to both technical and non-technical audiences. • Participate in on-call rotation and lead high-severity incident response, including post-mortems and systemic remediation.
