We are looking for a Senior iOS Engineer to own Sekai’s iOS app and help us build a fast, polished, AI-native consumer experience. This role is for someone with strong iOS experience, good consumer product taste, and the ability to move quickly in a startup environment. You should keep up with the latest Apple platform updates, understand what great mobile apps feel like, and be excited to use AI to rethink how fast a small team can build.

You will work closely with Product, Design, Backend, and Mobile engineers to improve the iOS app experience, ship new features, and help define our AI-native mobile development workflow.

• Work across native iOS, hybrid mobile, and web-based app experiences when needed
• Partner closely with Product, Design, Backend, and Mobile engineers to move from idea to shipped product quickly
• Use AI development tools to accelerate coding, debugging, refactoring, and product iteration

Qualifications

• Strong professional experience building and shipping iOS apps
• Deep familiarity with Swift, iOS SDK, and modern iOS development practices
• Experience working on consumer mobile apps with high standards for UX, performance, and reliability
• Experience owning projects end-to-end in a startup, 0-to-1 product environment, or similarly fast-moving team
• AI-native mindset: you actively use AI tools to build faster, explore better implementation paths, and improve engineering productivity
• Strong product sense and willingness to work closely with design and product teams

Nice to Have

• Experience with social, entertainment, creator, gaming, UGC, or feed-based consumer products
• Experience with React Native, Flutter, WebView, or other hybrid mobile architecture
• Familiarity with Android, backend systems, or full-stack product development
• Experience working on AI-native products or teams that heavily use AI in day-to-day development

Benefits

• Work with an AI-native team
• Move fast and own meaningful problems
• Flexibility to explore new ideas from an early stage
