Member of Technical Staff (iOS Engineer, Computer Growth)

We are seeking an experienced iOS Engineer to join our Growth team at Perplexity. You will work on the full mobile funnel, including install, activation, onboarding, push and lifecycle messaging, conversion, retention, and in-app purchase moments. As a mobile growth engineer, you will be responsible for end-to-end projects, such as rebuilding onboarding as a series of experiments, wiring in-app purchase and paywall surfaces to our billing systems, and shipping notification experiences.

The Growth team at Perplexity translates behavioral signals, model outputs, and fast experimentation into durable product surfaces used across consumer and enterprise workflows. You will move fast, run many experiments in parallel, and own the outcome end-to-end, while respecting the constraints mobile brings.

Our culture is built around craftsmanship, ownership, entrepreneurship, scholarship, and partnership. We value high-quality products, and you will have the opportunity to work with a talented team to pursue knowledge and truth.

Responsibilities:

• Design, build, and own growth surfaces across the mobile funnel on iOS.
• Lead experiments end-to-end, from hypothesis and instrumentation through implementation, analysis, and rollout.
• Own in-app purchase and paywall surfaces, including billing integrations and subscription flows.
• Build push and lifecycle notification experiences that earn their opt-in.
• Partner with web and design engineers to ensure cross-platform surfaces feel native.
• Optimize app store performance and attribution.
• Collaborate with Product, Design, Data Science, Monetization, Marketing, and the core Mobile team to translate behavioral signals into durable product surfaces.

Qualifications:

• 3+ years of professional mobile engineering experience shipping consumer apps at meaningful scale on iOS.
• Strong native skills in Swift, SwiftUI, or Objective-C.
• Experience owning a full release cycle, including build and release tooling, phased rollouts, and store review.
• Strong execution and ability to ship many experiments and product improvements in parallel.
• Familiarity with A/B testing and experimentation platforms.
• Comfort with data-informed decision-making and ability to pull, segment, and interpret funnel data.
• Strong product judgment and ability to translate user behavior and growth opportunities into simple, effective technical solutions.

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.
• ASO experience, including store listing experiments and localized metadata.
