Senior Software Engineer II, Mobile - Revenue Experimentation (AI Native)

Life360

3d • $118,500 - $216,500 • Remote

About The Position

Life360 is hiring an AI-Native Senior Software Engineer II to join the Revenue Experimentation team. This role is central to designing and shipping growth and monetization experiments across the Life360 app and advancing AI-native development. The engineer will take hypotheses and turn them into running, safely-instrumented experiments, defaulting to shipping and iterating quickly. They will manage dozens of concurrent tests, evolve AI-native engineering workflows, and contribute playbooks for the broader mobile organization. The role is Android-first but open to candidates willing to build across iOS, web, or backend. Success in the first year includes owning end-to-end delivery of multiple experiment surfaces, shipping improvements without a fully scoped spec, and having an introduced 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.
• 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.
• Agency — You don't wait to be told what to do. Given a rough hypothesis or a half-finished doc, you can get a working version in front of users without needing a fully-specced ticket first, and you take responsibility for the outcome, not just the task.
• Ownership mentality — You own your work from design through production and beyond, including what happens when the experiment doesn't go as planned.
• Taste and craft — You have opinions about what a good experiment, a good rollout, and a good user experience look like, and you can articulate why — not just execute a spec.
• Growth mindset — You structure problems precisely, learn quickly, show interest outside "your lane," and are always happy to try something new.
• 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.
• Collaborative approach — You communicate clearly, work well across teams, and value diverse perspectives; you give and take feedback well.

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, pricing, or onboarding surfaces at consumer scale.
• Deep in at least one of Kotlin/Android, Swift, or React, and comfortable shipping in another.
• Contributions to mobile open source or internal developer tooling.

Responsibilities

• Design and build high-quality Android growth and monetization features and experiments — subscription paywalls and pricing tests, ad placement and mediation experiments, one-time purchase (IAP) flows, and upsell/upgrade surfaces — 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 — pushing back when a hypothesis or plan doesn't hold up.
• Work with AI (Claude Code or equivalent) as a first-class collaborator — your primary workflow involves orchestrating agents to create specs, generate 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, reliable Android experiences to tens of millions of users, with strong attention to startup time, memory, battery, ANR, and crash-free rates.
• Take ambiguous or partially-specced ideas and get a working version in front of real users fast — treating the first cut as a learning tool, not a final answer.
• 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.
• Mentor other engineers and contribute to team processes, technical standards, and the evolution of the team's AI-native engineering practices.

Benefits

• Medical, dental, vision, life and disability insurance plans (100% paid for US employees). We offer life and disability as well as supplemental plans for medical and dental for Canadian employees.
• 401(k) plan with company matching program in the US and RRSP with DPSP plan for Canadian employees.
• Paid parental leave.
• Mental Wellness Program & Employee Assistance Program (EAP) for mental well-being.
• Generous time off: flexible PTO, companywide holidays throughout the year plus summer and winter shutdowns.
• Learning & Development programs.
• Equipment, tools, and reimbursement support for a productive remote environment.
• Free Life360 Platinum Membership and Tile trackers.
