Member of Technical Staff (iOS Engineer, Computer Growth)

Perplexity AI; New York (NY); On-site; USD 140,000 - 190,000; Full time

Job summary

Perplexity AI seeks a mobile growth engineer for iOS to own the full funnel—from install to paid upgrade—across Perplexity, Comet, and Computer. You’ll run experiments end-to-end, wire paywalls to billing, and ship native, durable growth surfaces with cross-functional partners.

You’ll push the boundaries of growth on a fast-moving team, balancing release cycles, store reviews, and platform fragmentation while delivering measurable improvements in activation, retention, and monetization.

Qualifications

• You have 3+ years of professional mobile engineering experience shipping consumer apps on iOS.
• Strong experience with native iOS development and modern Swift/SwiftUI/Obj-C.
• Familiar with A/B testing and experimentation platforms and in-app payment systems.

Responsibilities

• Own end-to-end growth experiments from hypothesis to rollout across iOS.
• Design, build, and own growth surfaces including install, activation, onboarding, lifecycle, and paid upgrades.
• Own in-app purchase and paywall surfaces with billing integrations and pricing experiments.
• Build push and lifecycle notifications to improve retention and engagement.
• Collaborate with Product, Design, Data Science, Monetization, Marketing, and Mobile teams to translate signals into durable product features.
• Move fast: ship many experiments in parallel while managing store release constraints.

Job description

• As a mobile growth engineer at Perplexity, you’ll work across the full mobile funnel — install, activation, onboarding, push and lifecycle messaging, conversion, retention, and in-app purchase moments — for Perplexity, Comet, and Computer on iOS. Engineers are responsible for end-to-end projects: rebuilding onboarding as a series of experiments, wiring in-app purchase and paywall surfaces to our billing systems, shipping notification experiences people actually keep enabled, and turning ASO and deep-link work into measurable adoption
• Growth at Perplexity goes beyond incremental funnel optimization
• The team sits close to the core product — we translate behavioral signals, model outputs, and fast experimentation into durable product surfaces used across consumer and enterprise workflows
• You’ll move fast, run many experiments in parallel, and own the outcome end-to-end, while respecting the constraints mobile brings: release cycles, store review, and version fragmentation
• 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

Strong product judgment; you translate user behavior and growth opportunities into simple, effective technical solutionsFamiliarity with A/B testing and experimentation platforms (Eppo, Statsig, Optimizely, or in-house equivalents) especially inside a versioned appComfort data-informed decision-making — you can pull, segment, and interpret your own funnel dataStrong execution: you ship many experiments and product improvements in parallel and drive them to a clear outcomeExperience owning a full release cycle: build and release tooling, phased rollouts, store review, crash and regression monitoring, and rolling back safelyStrong native skills (eg. Swift/SwiftUI/Objective-C) — and the willingness to flex into other parts of the stack to unblock yourself and othersSelf-motivated with strong ownership instincts; you propose experiments, ship features ahead of schedule, and drive improvements without asking for permission3+ years of professional mobile engineering experience shipping consumer apps at meaningful scale on iOSGenuine interest and adoption of AI products and willingness to learn quicklyDirect experience on a growth or experimentation-heavy teamDeep experience with in-app paymentsExperience with mobile attribution and measurement stacks (AppsFlyer, Adjust, Branch) and paid mobile acquisitionASO experience, including store listing experiments and localized metadataComfort reaching into the backend or web stack to unblock yourself end-to-endTime spent at a fast-growing startup or on a high-ownership engineering team
