The Opportunity

We are transitioning our massive enterprise application into a modern, future-proof codebase. We are looking for a Senior iOS Engineer who specializes in declarative UI to lead this charge. All new feature development is done exclusively in SwiftUI.

You will be working in a sophisticated architecture where modern SwiftUI views are powered by a shared business logic layer written in Kotlin Multiplatform (KMP). If you want to leave UIKit storyboards behind and focus on building reactive, declarative interfaces at scale, this is the role for you.

Our Tech Stack

• Languages: Swift (Advanced), Kotlin (for KMP/Shared Logic).
• UI Framework: SwiftUI (100% for new features).
• Architecture: Clean Architecture + MVVM + Coordinator Pattern.
• Modularization: 100% Swift Package Manager (SPM). We strictly separate our code into feature modules (Logic, DataStore, Models, KotlinCore).
• Testing: XCTest with BDD (Behavior Driven Development) practices.
  
  

What You’ll Do

• Build in SwiftUI: Design and implement complex, data-driven interfaces using purely declarative patterns. You will own the UI/UX for all upcoming roadmap features.
• Architect with MVVM-C: Implement scalable navigation and state management using ViewModels and Coordinators, ensuring your SwiftUI views remain lightweight and testable.
• Interface with KMP: Wire up your SwiftUI views to our shared KotlinCore business logic. You’ll work at the intersection of native UI and cross-platform logic.
• Modularize: Build reusable SwiftUI components and packages that can be shared across our modular architecture.
• Quality First: Write robust unit tests for your ViewModels and Logic, using our custom BDD helpers to ensure reliability.
  
  

Technical Leadership & Influence

Beyond the code, you will act as a bridge between technical strategy and product execution. You will partner closely with Product Managers and Stakeholders to translate business requirements into scalable technical roadmaps, proactively identifying risks. As a senior leader, you’ll mentor junior engineers, drive architectural alignment across feature teams, and champion engineering excellence. You don't just follow a spec; you influence the "how" and the "why," ensuring our technical choices support long-term business goals and organizational velocity.

What We’re Looking For

• SwiftUI Mastery: You aren't just "learning" SwiftUI; you know how to handle complex navigation, PreferenceKeys, strict concurrency, and data flow (@State, @Environment, @Binding) without creating massive re-render cycles.
• Architectural Discipline: You understand Clean Architecture. You know why we separate the "View" from the "UseCase" and how to implement that boundary cleanly.
• Modern Swift Patterns: You are proficient with Swift 5.9+ features, structured concurrency (Async/Await), and generic programming.
• Modular Mindset: You have experience working in a multi-module environment using Swift Package Manager (SPM).
  
  

Bonus Points

• Kotlin Multiplatform (KMP): Experience or a strong interest in how Swift consumers interact with Kotlin-generated shared code.
• On-Device AI & Machine Learning: Experience with Core ML or Apple Intelligence APIs to build "smart" features that leverage on-device processing.
• Computer Vision: Familiarity with Vision framework or integrating ML models into SwiftUI camera/image workflows.
• Deep Linking: Experience architecting navigation flows that support deep linking into specific SwiftUI views.
• Design Systems: Experience building atomic design components in SwiftUI.
  
  

Why Join Us?

• No Legacy Drag: We are committed to writing new features the "right way" using SwiftUI. You won't be stuck maintaining Obj-C or fighting AutoLayout constraints.
• Cutting Edge Architecture: Work on a real-world implementation of KMP + SwiftUI at enterprise scale.
• Impact: Your code will define the visual and functional future of the client’s mobile platform.
