Senior Software Engineer II, Mobile (iOS) - Global Monetization (AI Native)

Life360 is hiring a Senior Software Engineer II for its Global Monetization team to build and improve iOS purchase experiences for members in markets around the world. The role owns solutions from proposal through launch, including pricing, packaging, payments, localized purchase flows, staged rollouts, and reliable mobile performance, while helping advance AI-native engineering practices.

Responsibilities:

• Partner with product managers to shape the roadmap: bring proposals and help write the product specs
• Prototype fast: turn rough ideas into something clickable before the spec is final, so the team reacts to a real thing instead of a document, using AI tools to get there in hours, not weeks
• Build the surfaces that carry market-specific pricing, packaging, and positioning: paywalls, plan selection, upsell and upgrade flows, and one-time purchase flows, localized and tested across storefronts and currencies
• Work with product, design, data science, and analytics, and with finance and legal when pricing, payments, or regional rules require it
• Own staged rollouts end-to-end: ramp exposure, monitor guardrails, and decide whether to hold, roll back, or scale
• Ship polished, performant, reliable experiences, with strong attention to launch time, memory, battery, hangs, and crash-free rates
• Contribute to architectural decisions, code reviews, and a culture of craft and continuous improvement across the mobile codebases
• Mentor other engineers and contribute to team processes, technical standards, and the evolution of the team's AI-native engineering practices

Requirements:

• 6+ years of iOS software engineering experience shipping production apps at consumer scale
• Experience owning a problem end-to-end, from deciding what to build through production, with AI coding assistants (Claude Code, Cursor, Codex, etc.) as a daily tool and a result you can point to
• Experience with in-app purchases and subscription platforms, including entitlement handling, receipt/transaction validation, and refund and restore flows
• Experience shipping to multiple App Store storefronts, including regional pricing, localization, and regulatory differences in payment rules
• Strong proficiency with Swift, SwiftUI, and UIKit; deep familiarity with the modern iOS toolchain (Xcode, Swift Concurrency with async/await and actors, Combine)
• Experience with iOS architecture patterns (MVVM, TCA, Clean Architecture, modularization with Swift Package Manager) 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, hang, and crash diagnostics (Instruments, MetricKit, Xcode Organizer, Crashlytics or equivalent)
• Experience with CI/CD for iOS (Fastlane, Xcode Cloud, GitHub Actions, Bitrise, or similar) and App Store Connect release management
• Experience communicating technical trade-offs clearly to product, design, and non-engineering partners
• Bachelor's degree in a technical field, or equivalent experience
• Background in mobile analytics pipelines (Amplitude, Segment, Snowflake/Databricks downstream)
• Experience working with an experimentation platform (Statsig, LaunchDarkly, Optimizely, Eppo, GrowthBook, or similar)
• Experience with mobile ad SDKs and mediation (AdMob, AppLovin MAX, or similar)
• Contributions to mobile open source or internal developer tooling
• AI-assisted Android development experience
