Swift/SwiftUI/Objective-C) - and the willingness to flex into other parts of the stack to unblock yourself and others. * Experience owning a full release cycle: build and release tooling, phased rollouts, store review, crash and regression monitoring, and rolling back safely. * Strong execution: you ship many experiments and product improvements in parallel and drive them to a clear outcome. * Familiarity with A/B testing and experimentation platforms (Eppo, Statsig, Optimizely, or in-house equivalents) especially inside a versioned app. * Comfort data-informed decision-making - you can pull, segment, and interpret your own funnel data. * Strong product judgment; you translate user behavior and growth opportunities into simple, effective technical solutions. * Self-motivated with strong ownership instincts; you propose experiments, ship features ahead of schedule, and drive improvements without asking for permission. * Genuine interest and adoption of AI products and willingness to learn quickly. Nice to have * Direct experience on a growth or experimentation-heavy team * Deep experience with in-app payments * Experience with mobile attribution and measurement stacks (AppsFlyer, Adjust, Branch) and paid mobile acquisition. * ASO experience, including store listing experiments and localized metadata. * Comfort reaching into the backend or web stack to unblock yourself end-to-end. * Time spent at a fast-growing startup or on a high-ownership engineering team. ## Description * Design, build, and own growth surfaces across the mobile funnel - install, activation, onboarding, lifecycle, conversion, retention, and paid upgrade moments - on iOS. * Lead experiments end-to-end, from hypothesis and instrumentation through implementation, analysis, and rollout, shipping many in parallel despite app release cadence. Build the flag-driven and server-driven patterns that let us test without waiting on a store release. * Own in-app purchase and paywall surfaces: billing integrations, subscription and credit purchase flows, entitlement correctness, and pricing and packaging experiments. * Build push and lifecycle notification experiences that earn their opt-in - permission prompts, targeting, timing, deep links back into the right task, and the instrumentation to prove they drive retention rather than churn. * Make cross-platform surfaces feel native. Partner with web and design engineers so onboarding, upsells, and in-task nudges are consistent across web, iOS, and Android * Partner with rest of Growth to optimize app store performance and attribution * Hill-climb on the metrics that matter: install-to-activation, D1/D7/D30 retention, notification opt-in and engagement, paid conversion, and habit formation, instrumented with clean data and trustworthy experiment readouts. * Partner closely with Product, Design, Data Science, Monetization, Marketing, and the core Mobile team to translate behavioral signals into durable product surfaces. ## Related Videos - [Xcode development redefAIned](https://www.wearedevelopers.com/videos/100195-xcode-development-redefained) - [Quantum computing for developers: Solving optimization problems with Qiskit](https://www.wearedevelopers.com/videos/777-quantum-computing-for-developers-solving-optimization-problems-with-qiskit) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [From Zero to Mobile Developer in 45 Minutes With SwiftUI](https://www.wearedevelopers.com/videos/183-from-zero-to-mobile-developer-in-45-minutes-with-swiftui) - [SwiftUI In Production](https://www.wearedevelopers.com/videos/134-swiftui-in-production) - [Edge AI on iOS: Beyond the Cloud, Designing the Next Generation of Intelligent On-Device Apps](https://www.wearedevelopers.com/videos/100225-edge-ai-on-ios-beyond-the-cloud-designing-the-next-generation-of-intelligent-on-device-apps) ## Related Articles - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [A Guide to Choosing the Right Tools for App Developers](https://www.wearedevelopers.com/magazine/391-a-guide-to-choosing-the-right-tools-for-app-developers) - [Dev Digest 118 - not a total recall](https://www.wearedevelopers.com/magazine/452-dev-digest-118-not-a-total-recall) - [Dev Digest 139 - Soft and hard queries](https://www.wearedevelopers.com/magazine/487-dev-digest-139-soft-and-hard-queries) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline)
