Staff Software Engineer AI-Native, International

Life360 is a company dedicated to keeping families connected through innovative technology. They are seeking a Staff Software Engineer who will play a crucial role in building AI-native products for international markets, focusing on high-quality services and collaboration with AI tools.

Responsibilities:

• Design and build high-quality API and services for the international adaptation of Life360 — services that are life saving, and genuinely useful
• Build with our global customers in mind by applying internationalization best practices from the start
• Work with AI (Claude Code) as a first-class collaborator — your primary workflow involves orchestrating agents to create specs, generate code and tests, verify results, and perform reviews
• Help define and codify AI-Native engineering practices for the International 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
• Hold a high bar for quality end-to-end: you define what 'done' means, instrument your work for observability, and treat post-launch behavior as part of the job — not someone else's problem
• 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

Requirements:

• 8+ years of experience building and operating high-quality, consumer-scale services
• 1+ years of hands-on experience prompting, evaluating, and building with LLMs
• Strong proficiency in cloud development using modern Java, Kubernetes, AWS and streaming technologies
• 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
• 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 our international members - including those with lower end mobile devices and inconsistent network connectivity. Building highly localized experiences is critical to bringing the value of Life360 to global markets
• Bachelor's Degree in a Technical field, or equivalent experience
