About The Position

Life360 is seeking an AI-Native Senior Software Engineer II, Mobile. This role is central to the Experimentation & ML Intelligence team, focusing on designing and shipping growth experiments across the Life360 app and leveraging AI for development. The engineer will design and build features, flows, and experiments to drive activation, conversion, and retention, running dozens of concurrent tests. They will also evolve AI-Native engineering workflows and publish playbooks for the broader mobile organization. The role is Android-first but encourages cross-platform development (iOS, web, backend) when needed. Success in the first year involves owning end-to-end delivery of multiple experiment surfaces and having at least one AI-native workflow adopted beyond the team.

Requirements

6+ years of Android software engineering experience shipping production apps at consumer scale.
At least 1 year of hands-on experience prompting, evaluating, and building with LLMs.
Strong proficiency with Kotlin and Jetpack Compose (and the Android View system); deep familiarity with the modern Android toolchain (Android Studio, Kotlin Coroutines, Flow).
Experience with Android architecture patterns (MVVM, MVI, Clean Architecture, Jetpack/ViewModel/Navigation, Hilt or Dagger) in a large, multi-team codebase.
Comfort with mobile experimentation concepts: feature flagging, A/B testing, exposure logging, holdouts, and guardrail metrics.
Solid grounding in mobile performance, memory, battery, ANR, and crash diagnostics (Android Studio Profiler, Perfetto/Systrace, Macrobenchmark, Crashlytics or equivalent).
Experience with CI/CD for Android (Gradle, Fastlane, GitHub Actions, Bitrise, or similar) and modular build systems (Gradle modules, Maven).
Deep experience with agentic workflows, prompt engineering, context-window management, and MCP/function calling — you understand the research-plan-implement cycle but don't outsource thinking to agents.
Bachelor's degree in a technical field, or equivalent experience.
Growth mindset - You structure problems precisely, you learn quickly, you can show interest outside “your lane”, and you are always happy to try something new
Collaborative approach - You communicate clearly, work well across teams, and value diverse perspectives
Ownership mentality - You take responsibility for your work from design through production and beyond
AI-native working style - You use AI tooling (Claude Code or equivalent) as a genuine development partner: delegating discrete tasks, reviewing outputs critically, and running parallel workstreams rather than hand-holding one agent at a time
Thoughtful communication - You can explain technical tradeoffs and articulate ideas effectively

Nice To Haves

Experience working with an experimentation platform (Statsig, LaunchDarkly, Optimizely, Eppo, GrowthBook, or similar).
Background in mobile analytics pipelines (Amplitude, Segment, Snowflake/Databricks downstream).
Familiarity with Bayesian or sequential testing methods and how they affect client-side implementation.
Previous work on subscription, paywall, or onboarding surfaces at consumer scale.
Contributions to mobile open source or internal developer tooling.

Responsibilities

Design and build high-quality Android growth features and experiments — across onboarding, activation, feature awareness, subscription conversion, and retention — running dozens of concurrent tests across the Life360 app.
Partner with product, design, data science, and analytics to translate hypotheses into shippable experiments, and turn results into the next decision.
Work with AI (Claude Code) as a first-class collaborator — your primary workflow involves orchestrating agents to create specs, generate Kotlin code and tests, verify results, and perform reviews.
Instrument experiments accurately — exposure logging and analytics — so the results downstream teams rely on are trustworthy.
Ship polished, performant, and reliable Android experiences to tens of millions of users — with strong attention to startup time, memory, battery, ANR, and crash-free rates.
Help define and codify AI-Native Android engineering practices for the team, establishing playbooks the broader mobile org can adopt.
Contribute to architectural decisions, code reviews, and a culture of craft and continuous improvement on the Android codebase.
Participate in on-call rotation and incident response for mobile experiments and releases.
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 Android features you own.
