Hello,
We are called People More because we treat our employees with respect, but also because the projects we work on are for people and should be easy and pleasant to use. We are technological, but we look at the bigger picture :)
The company is made up of people with a huge client base in the country and abroad, for whom we build projects from scratch (UX, UI, frontend, backend, mobile) or in part. We work directly for our clients and also support our partners in their own solutions. This ensures a wide range of projects and the ability to change! We work with clients all over the world.
For the project that we are working on with our partner, we are looking for Senior iOS Engineer – FinTech Platform (Swift / SwiftUI / UIKit).
Your duties will include
- Design, develop, and maintain the architecture of a production-grade iOS application, ensuring clear module boundaries, layered structures, and well-managed dependencies.
- Build and enhance native iOS applications using Swift, SwiftUI, and UIKit.
- Implement asynchronous and reactive programming patterns with async/await, Actors, and Combine.
- Develop data persistence and security mechanisms using Core Data, SwiftData, and Keychain Services.
- Contribute to the entire software development lifecycle, including PRD preparation, technical specifications, testing, feature-flag-based releases, and structured event tracking.
- Create and maintain automated unit and UI tests using XCTest and XCUITest.
- Analyze and optimize application performance with Instruments, including Time Profiler, Allocations, Leaks, and Core Animation.
- Ensure production stability by monitoring application crashes, investigating issues, and preventing regressions using tools such as Crashlytics.
- Build, improve, and maintain CI/CD pipelines with Fastlane, Xcode Cloud, or equivalent technologies.
- Develop integrations between native mobile functionality and web-based components, including WKWebView, Universal Links, Deep Linking, and Handoff.
- Work closely with Engineering and Product Managers to shape requirements, prioritize the backlog, and propose effective native iOS solutions.
- Collaborate with backend development teams on API contracts, authentication mechanisms, and event schemas.
- Support production incident resolution and participate in post-incident reviews when necessary
Requirements that must be met

- Solid production experience with SwiftUI and UIKit, including a good understanding of their rendering lifecycles.
- Practical knowledge of architectural approaches such as Clean Architecture, MVVM, and/or MVI, with an understanding of modular design and separation of concerns.
- Experience managing dependencies with Swift Package Manager and/or CocoaPods.
- Good understanding of dependency inversion principles and designing maintainable, testable code.
- Hands-on experience with Core Data, SwiftData, and Keychain Services
- Knowledge of URLSession, certificate pinning, and structured error-handling mechanisms.
