Senior iOS Engineer

Full Time
  • September 13, 2026
  • Employment Info

    What you’ll do

    • 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
    • Mentor mobile engineers and raise the team’s overall engineering and product judgment

    Requirements

    • 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
    Experience
    • 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
    • Kotlin / KMM experience is a plus (but not a requirement)
    Education
    • Bachelor’s degree or above. Shipped work, judgment, and product taste matter more than credentials.
    Nice to have
    • Experience of a fast-growing consumer app, or your own indie app on the App Store
    • Interest in anime, otaku culture, creator communities, or AI image generation
