• Take charge of in-app purchase systems and paywall mechanisms, which include managing billing integrations, subscription processes, credit purchase flows, entitlement accuracy, and conducting pricing experiments.
• Develop engaging push notifications and lifecycle messaging that users actively opt into, paying close attention to permission prompts, targeting strategies, timing, deep linking, and evaluating their impact on user retention.
• Collaborate with web and design engineers to ensure a consistent user experience across platforms, including web, iOS, and Android, particularly in areas like onboarding, upselling, and in-task nudges.
• Work alongside the broader Growth team to enhance app store performance and improve attribution metrics.
• Drive improvements in key performance indicators such as install-to-activation rates, retention metrics (D1/D7/D30), notification engagement, paid conversion rates, and user habit formation, leveraging reliable data and experimental results.
• Partner closely with teams in Product, Design, Data Science, Monetization, Marketing, and the core Mobile team to translate user behavior insights into impactful product features.

Requirements

• A minimum of 3 years of experience in mobile engineering, specifically in delivering consumer applications at scale on iOS.

• Demonstrated ability to execute effectively, managing multiple experiments and product enhancements simultaneously while achieving measurable outcomes.
• Familiarity with A/B testing and experimentation platforms like Eppo, Statsig, Optimizely, or similar internal tools, particularly in the context of versioned applications.
• Comfortable making data-driven decisions, with the capability to extract, segment, and analyze funnel data.
• Strong product judgment, with the ability to translate user behavior and growth opportunities into straightforward, effective technical solutions.
• Self-driven with a robust sense of ownership, capable of proposing experiments, delivering features efficiently, and proactively driving improvements.
