iOS Growth Engineer (Growth & Experimentation)

Perplexity; San Francisco (CA); On-site; USD 220,000 - 405,000; Full time

Job summary

Perplexity's Growth team is seeking a mobile growth engineer to own the end-to-end iOS funnel across Perplexity, Comet, and Computer. You will design and run experiments, implement onboarding, in-app purchases, and push notifications, and collaborate with product, design, data science, monetization, marketing, and mobile engineering.

You will ship multiple experiments in parallel within release cycles, work with ASO and deep-linking, and ensure measurement with trustworthy readouts.

Qualifications

• 3+ years of professional mobile engineering experience shipping consumer apps at meaningful scale on iOS.
• Strong native skills (eg. 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.

Responsibilities

• 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.
• 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.
