Member of Technical Staff (iOS Engineer, Computer Growth)

Details

The Growth team owns the mobile product loops that help users discover, adopt, and build lasting habits around Perplexity's AI experiences. As a mobile growth engineer, you will work across the full mobile funnel for Perplexity, Comet, and Computer on iOS, including installation, activation, onboarding, push and lifecycle messaging, conversion, retention, and in-app purchases. You will move quickly, run multiple experiments in parallel, and own projects end-to-end while working within mobile release cycles, app store review, and version fragmentation.

Responsibilities

• Design, build, and own growth surfaces across the iOS mobile funnel, including installation, activation, onboarding, lifecycle messaging, conversion, retention, and paid upgrades.
• Lead experiments end-to-end, from hypothesis and instrumentation through implementation, analysis, and rollout.
• Build flag-driven and server-driven patterns that support experimentation without waiting for an App Store release.
• Own in-app purchase and paywall surfaces, including billing integrations, subscription and credit purchase flows, entitlement correctness, and pricing and packaging experiments.
• Build push and lifecycle notification experiences, including permission prompts, targeting, timing, deep links, and retention instrumentation.
• Partner with web and design engineers to make onboarding, upsells, and in-task nudges consistent across web, iOS, and Android.
• Partner with the Growth team to optimize app store performance and attribution.
• Improve install-to-activation, D1/D7/D30 retention, notification opt-in and engagement, paid conversion, and habit formation using clean data and trustworthy experiment readouts.
• Collaborate with Product, Design, Data Science, Monetization, Marketing, and the core Mobile team to translate behavioral signals into durable product surfaces.

Requirements

• 3+ years of professional mobile engineering experience shipping consumer apps at meaningful scale on iOS.
• Strong native iOS skills, such as Swift, SwiftUI, and Objective-C, with the willingness to work across other parts of the stack when needed.
• Experience owning a full release cycle, including build and release tooling, phased rollouts, App Store review, crash and regression monitoring, and safe rollbacks.
• Strong execution skills and the ability to ship multiple experiments and product improvements in parallel.
• Familiarity with A/B testing and experimentation platforms such as Eppo, Statsig, Optimizely, or in-house equivalents, especially in versioned apps.
• Ability to pull, segment, and interpret funnel data for data-informed decision-making.
• Strong product judgment and the ability to translate user behavior and growth opportunities into simple, effective technical solutions.
• Self-motivated, with strong ownership instincts and the ability to propose experiments and drive improvements independently.
• Genuine interest in and adoption of AI products, with a willingness to learn quickly.

Nice to Have

• Experience on a growth or experimentation-heavy team.
• Deep experience with in-app payments.
• Experience with mobile attribution and measurement platforms such as AppsFlyer, Adjust, or Branch, and with paid mobile acquisition.
• ASO experience, including store listing experiments and localized metadata.
• Comfort working with backend or web technologies to unblock end-to-end work.
• Experience at a fast-growing startup or on a high-ownership engineering team.
