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).
