Senior Software Engineer

Life360’s mission is to keep people close to the ones they love. Our category-leading mobile app,Tile tracking devices, and Pet GPS tracker empower members to protect the people, pets, and things they care about most with a range of services, including location sharing, safe driver reports, and crash detection with emergency dispatch. Life360 serves approximately 97.8 million monthly active users (MAU), as of March 31, 2026, across more than 180 countries. 

Life360 delivers peace of mind and enhances everyday family life with seamless coordination for all the moments that matter, big and small. By continuing to innovate and deliver for our customers, we have become a household name and the must-have mobile-based membership for families (and those friends who are basically family).

Life360 has more than 500 (and growing!) remote-first employees. For more information, please visit life360.com.

We are building an AI native company where AI is an integral part of how we build and operate. AI tool usage during interviews varies by role. You may be asked to demonstrate proficiency with AI tools, discuss how you leverage AI, or complete interview exercises without AI assistance. Your Recruiter will provide clear guidance as you move through the interview process.

Undisclosed use of AI not previously discussed with or approved by your Recruiter may impact your candidacy.

The International team at Life360 is building the next frontier of meaningful connection — bringing Life360's peace-of-mind platform to families everywhere, regardless of where in the world they live. Our mission is to make the product feel native to every market we enter: localized experiences, regionally relevant features, and the kind of trust that only comes from truly understanding how families in different cultures stay safe, connected, and close. We're expanding Life360's reach beyond its home market so that every family — whether in São Paulo, Berlin, or beyond — has access to the tools that help them navigate the beautiful, chaotic reality of everyday life together.

We are a product-minded, AI-Native engineering team. That means AI isn’t just a tool we use — it’s how we work. We’ve redesigned our team workflows around AI, treating it as a first-class collaborator at every stage: ideation, coding, testing, review, and iteration. We ship faster and go deeper because of it, and we’re looking for someone who wants to help define what that looks like at scale.

You'll own the feature layer that makes Life360 feel native to the markets we're expanding into — starting with Brazil and eventually expanding throughout LATAM. That means taking existing Life360 capabilities and adapting them for local reality: safety-first features tailored to how families in Brazil actually live, alternate payment integrations (think carrier billing and local payment rails alongside the app stores), and the UX decisions that make the product feel built in São Paulo, not exported from San Francisco.

You'll work directly with the International Features PM and report into the Senior Director of International. The roadmap is early and yours to help shape — you'll be one of the first engineers on the ground, partnering closely with products to define what adaptation actually means market by market.

You'll also build and evolve our AI-Native engineering workflows — from how we write code to how we think about team velocity. You'll evolve the standard others follow.

Mobile experience is strongly preferred (iOS or Android), though exceptional full-stack engineers are also encouraged to apply.

This role is a full-time CLT position, employed through our Employer of Record (EOR) partner in Brazil.

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.
• Judgment and ownership: AI-generated code gets the same review you'd give any PR. You are accountable for everything you ship.
• 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.
• 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.
• Continuous learning: The tooling is changing fast. You stay current and bring recommendations to the team when something would meaningfully improve how we work.

• →Design and build high-quality features for our Latin American members — experiences that are safe, intuitive, 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 Circle Expansion team, establishing playbooks the broader org can adopt.
• →Build across the full stack (iOS, Android, Cloud) 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.

• 5+ years of experience building high-quality, consumer-scale software products.
• At least 1 year of hands-on experience prompting, evaluating, and building with LLMs.
• Strong proficiency in mobile development (iOS or Android) — you know what great mobile UX feels like and how to build it. Web and backend experience (Java, Kubernetes, AWS) are valued alternatives.
• 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.
• You don't wait for the playbook — you write it. Defining what AI-Native engineering looks like in practice, for this team and the broader org, is part of the job.
• Empathy for the humans behind the product — an aging parent trying to stay independent, a parent tracking their pre-teen, a coach wrangling 20 families on game day.
• Bachelor’s Degree in a Technical field, or equivalent experience.

• Full stack mobile and cloud development experience.
• Experience localizing a product for non-US markets, including integrating market specific payment types.
• Experience tuning app performance for low-end mobile devices.

Our company’s mission-driven culture is guided by our shared values to create a trusted work environment where you can bring your authentic self to work and make a positive difference 

• Be a Good Person - We have a team of high integrity people you can trust. 
• Be Direct With Respect - We communicate directly, even when it’s hard.
• Members Before Metrics - We focus on building an exceptional experience for families. 
• High Intensity, High Impact - We do whatever it takes to get the job done.
