Senior / Staff iOS Engineer

About Utopai StudiosWe're building a cinematic AI storytelling experience that changes how stories get made. Our agentic platform lets creators go from idea to narrative video across formats, audiences, and platforms — fast. We're a small team that ships constantly, thinks from first principles, and believes the best creative tools haven't been built yet.The RoleWe're looking for a Senior or Staff iOS Engineer who builds the interfaces creators actually live in. You'll own the iOS app end-to-end — the capture flow, the editor, the agent interactions, the moments where someone goes from a half-formed idea to a finished scene on their phone — and you'll ship it yourself.This isn't a role where mobile means a thin wrapper around a web view. You'll architect the client, shape the interaction model, work directly with our research and design teams, and turn agent capabilities into responsive, native-feeling creative tools. The hard problems here aren't standard CRUD — you'll be inventing how humans collaborate with models on video, on a phone, at speed.How You WorkEngineering craft. You sweat the details — frame rate, gesture feel, memory pressure, the way a transition lands. You have a high bar and it shows in everything you ship.Ship fast. You'd rather get something in front of users this week than architect it for a month. You know when to refactor and when to land it.AI-native. You're already using Claude Code, Cursor, or similar tools to extend what you can build. AI is part of your workflow, not a novelty.What You Bring5+ years of iOS experience, with at least some of it at the senior or staff levelDeep iOS expertise — Swift, SwiftUI and/or UIKit, the actual mental model, not just the API surfaceExperience shipping and maintaining apps in the App Store at real scaleExperience architecting non-trivial iOS apps — state management, offline behavior, sync, performance on mid-tier devicesA sharp eye for interaction detail — you can tell when a gesture feels 50ms too slow and you know how to fix itExperience with video capture, playback, or media pipelines is a strong plusAndroid experience is a plusWeb/React experience is a plusBS in Computer Science or equivalent experience — we care more about what you've shipped than where you studied
