Life360 - Senior Software Engineer II, Mobile (iOS) - Global Monetization (AI Native)
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. • Nice-to-Have: • 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. • AI-Native Expectations • We use AI coding tools as a professional standard on this team. In practice: • Daily use — You use AI coding assistants for real, substantive tasks: analysis, coding, refactoring, testing, navigating codebases, and documentation, not just research or autocomplete. • Daily use • Judgment and ownership — AI-generated code gets the same review you'd give any PR. You are accountable for everything you ship. • Judgment and ownership • Velocity — We expect senior engineers who use AI well to operate with meaningful leverage, taking on problems that would otherwise require a larger team. • Velocity • Team leadership — You share what works, automate prompting strategies others can build on, and help teammates earlier in their AI workflow adoption get up to speed. • Team leadership • Continuous learning — The tooling changes fast. You stay current and bring recommendations to the team when something would meaningfully improve how we work. • Continuous learning
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.
