Job Description

Responsibilities Own major surfaces of a consumer app used by millions, driving them from idea to release and beyond Translate product hypotheses into polished, performant iOS experiences in Swift / S

Key Highlights

  • Own major surfaces of a consumer app used by millions, driving them from idea to release and beyond
  • Translate product hypotheses into polished, performant iOS experiences in Swift / SwiftUI, and set the quality bar for the team
  • Lead UI logic shared across platforms via Kotlin Multiplatform (KMM), collaborating closely with Android and Web frontend
  • Define how features are instrumented, run A/B experiments, and turn data into decisions on activation, retention, and engagement
  • Own user feedback and long term product success for your area, including the key metrics that define it

Qualifications

Required Qualifications

  • Deep iOS engineering skills with a track record of high-impact, user-facing features owned end to end
  • Strong in Swift and SwiftUI; confident with modern concurrency and scalable app architecture
  • Real product sense: you have opinions about UX and can tell good from “technically done”
  • User sympathy - you instinctively notice friction, jank, and confusing flows, and you advocate for the user in every tradeoff
  • Data-driven: you frame hypotheses, define metrics, and let dashboards and experiments guide iteration
  • Clear communicator who can align engineers, design, and leadership, and make tradeoffs explicit
  • Bias toward shipping and learning, while keeping reliability and UX from decaying under growth
  • 5–8+ years building and iterating on mobile products used by real users
  • Experience of leading a small team (2–5 engineers) and/or driving a cross-functional team toward a product goal
  • Experience as a product owner and/or owning key product metrics, not just shipping assigned tickets
  • Proven track record shipping iOS features and improving them based on feedback or metrics
  • Professional experience with B2C / consumer-facing products, presumably in gaming, social, etc. realm
  • Hands-on experience with A/B testing or product experimentation
  • Bachelor’s degree or above. Shipped work, judgment, and product taste matter more than credentials.
  • An interest in anime. When applying, please include the names of your top 5 favorite niche anime at the end of your message.

Preferred Qualifications

  • Kotlin / KMM experience.
  • Experience of a fast-growing consumer app, or your own indie app on the App Store
  • Interest in otaku culture, creator communities, or AI image generation
