Project/Client: Banking
Location: Baltic states and Poland (Remote)
Start Date: ASAP
Rate: 30 -38 EUR per hour
Language: English (B2+)
Role Overview:
We are looking for a skilled iOS Developer to join a team working on a native banking application. The role involves building and maintaining features within a highly modularized multi-module architecture using Swift and SwiftUI , following MVVM , RIB , and Clean Architecture principles. The developer will work with RESTful APIs , implement reactive patterns via Combine and Swift Concurrency, and contribute to security-focused modules including authentication, biometrics, and cryptographic signing. Collaboration across teams, code quality, and ownership mindset are key expectations for this role.
Key Responsibilities:
- Develop and maintain a native iOS banking application using Swift and SwiftUI.
- Work with RESTful APIs , networking, and JSON data formats via a modular networking layer.
- Build features within a highly modularized multi-module architecture (Tuist , Swift Package Manager ) following RIB , MVVM , and Clean Architecture principles.
- Implement reactive and asynchronous patterns using Combine and Swift Concurrency (async/await).
- Ensure solutions meet high standards of performance, security, and user experience --- including work on authentication, biometrics, device integrity, fraud checks, and cryptographic signing modules.
- Write and maintain unit tests (SwiftTest) and use generated mocks/test-support frameworks per module.
- Maintain high code quality, perform knowledge sharing, and take end-to-end ownership of delivered solutions.
- Collaborate using Git and contribute to CI/CD pipelines (Fastlane).
Must-Have Requirements:
- Proven experience in native iOS application development.
- Strong proficiency in Swift ; hands-on experience with SwiftUI (UIKit knowledge is a plus).
- Experience with Combine and/or Swift Concurrency (async/await, actors).
- Strong understanding of MVVM and Clean Architecture ; experience working in large, modularized codebases (Tuist , Swift Package Manager, or similar).
- Experience integrating RESTful APIs , handling JSON , and working with URLSession-based networking.
- Understanding of dependency injection patterns and modularization principles.
- Experience with unit testing (SwiftTest) and mocking/test-support tooling.
- Version control proficiency with Git.
- Good command of English (minimum B2).
Nice to Have:
- Experience with CI/CD pipelines (Fastlane).
- Knowledge of cryptography and secure coding practices (e.g. asymmetric cryptography, secure signing, biometric authentication).
- Familiarity with OWASP MASVS (Mobile Application Security Verification Standard).
- Experience with Apple Wallet / PassKit extensions.
- Experience with code generation/templating tools (e.g. Sourcery-style mock generation).
