Life360 - Senior Software Engineer, II
Requirements
• 5+ years of experience building and operating high-quality, consumer-scale services. • 1+ years of hands-on experience prompting, evaluating, and building with LLMs. • Full-stack proficiency spanning backend services and mobile client development (iOS and/or Android), with the versatility to work across the whole stack as needed. • Deep experience with agentic workflows, prompt engineering, context window management, and MCP/function calling. • A track record of using AI tooling to multiply your own output — not just as autocomplete, but as a genuine development partner. • A strong sense of ownership — you don't wait to be told what to fix, and you follow through past "it works on my machine" to "it works for the member, in production, at scale." • Strong communication and collaboration skills — you work well with product, design, and platform engineers. • A genuine excitement for defining what it means to be AI-Native — you're not waiting for the playbook, you want to write it. • Empathy for the humans behind the product — an aging parent trying to stay independent, or a family member trying to help from afar. • Bachelor's Degree in a Technical field, or equivalent experience. • Nice-to-Have • Experience with IoT, telematics, or embedded/hardware-adjacent systems. • Familiarity with Kafka, Kinesis, or other high-throughput streaming platforms. • Background with observability tooling (Prometheus, Grafana, OpenTelemetry, DataDog). • 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
• Ship end-to-end across the stack — from backend services and APIs through to the iOS and Android surfaces members actually use — moving fluidly between layers as the feature demands. • Work with AI (Claude Code) as a first-class collaborator — your primary workflow involves orchestrating agents to create specs, generate results, and perform reviews. • Help define and codify AI-Native engineering practices for the Verticals team, establishing playbooks the broader org can adopt. • Build across the full stack as needed — shipping polished, performant, and reliable experiences to tens of millions of users. • Collaborate closely with product managers and designers to turn complex user problems into elegant, scalable engineering solutions. • Contribute to architectural decisions, code reviews, and a culture of craft and continuous improvement. • Participate in on-call rotation and incident response. • Use agentic workflows to dramatically increase the delivery of strong outcomes — moving faster without sacrificing quality. • Mentor team members and contribute to team processes, technical standards, and help evolve the team's AI-native engineering practices. • Support performance, reliability, and accessibility across the features you own. • Adapt patterns and services built for Aging in Place to future verticals (Things, Pets) as team scope expands.
