Type: Full-Time

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 excelle
