About the Role

We are looking for an experienced Senior iOS Engineer to take ownership of a modern native iOS application built with Swift 6, SwiftUI and a modular Swift Package Manager architecture.

This is a hands-on engineering role where you will work closely with product, design, backend, platform and QA teams to deliver high-quality, scalable mobile features across reusable UI components, networking, authentication, real-time communication and secure identity-verification journeys.

You will contribute to both product delivery and the ongoing evolution of the iOS architecture, with a strong focus on modern Swift Concurrency, security, performance, code quality and maintainability.

Key Responsibilities

• Own, develop and maintain the native iOS application using Swift and SwiftUI

• Build modern SwiftUI features using Swift Concurrency, including async/await, actors, actor isolation and MainActor-aware UI development

• Contribute to a modular codebase built with Swift Package Manager, including reusable internal packages for networking, UI components and test mocks

• Integrate backend services through the application networking and identity layers, supporting authentication and API-based customer journeys

• Develop and maintain real-time application features using SignalR

• Integrate and maintain identity-verification capabilities using Jumio, including liveness, NFC and localization modules

• Develop secure device-capability journeys using camera, NFC and biometric authentication such as Face ID

• Build and maintain reusable SwiftUI components aligned with the application design system

• Write and maintain unit and UI tests and contribute to reliable, testable software design

• Support separate DEV, UAT and PROD application configurations, entitlements and environment-specific resources

• Contribute to build, release and App Store distribution processes, including code signing and provisioning

• Participate in code reviews, technical design discussions and continuous improvements to application quality and architecture

• Ensure development activities are carried out in line with applicable regulatory, security and compliance requirements

What We’re Looking For

• University degree in Computer Science, Engineering or a related field

• Minimum 5 years of professional experience in Swift and native iOS development

• Hands-on experience building production iOS features with SwiftUI

• Solid understanding of Swift Concurrency, including async/await, actors and actor isolation

• Experience with Swift Package Manager, modular iOS applications and reusable Swift packages

• Experience integrating backend APIs, authentication or identity services and third-party SDKs

• Knowledge of secure token storage using the iOS Keychain

• Strong experience with Xcode, Instruments and iOS debugging and performance-analysis tools

• Experience writing unit and UI tests using XCTest and XCUITest

• Experience with Xcode build configurations, code signing, provisioning and multiple application environments

• Familiarity with Git-based collaborative development workflows and code reviews

• Experience working in an Agile delivery environment

• Strong communication, ownership and collaboration skills

Nice to Have

• Experience with SignalR or another real-time communication technology

• Experience with Jumio or another KYC / identity-verification SDK

• Experience with NFC, camera, Face ID and secure mobile-onboarding journeys

• Experience developing reusable SwiftUI design systems and component libraries

• Knowledge of localization, image caching and SVG rendering on iOS

• Previous experience in fintech, wallets, payments or financial-services mobile applications

• Knowledge of iOS CI/CD pipelines, particularly in Azure DevOps

• Experience managing App Store builds, signing and distribution

What We Offer

• Fully remote working model within Greece

• Opportunity to take ownership of a modern, production-scale native iOS application

• Hands-on work with Swift 6, SwiftUI and modern Swift Concurrency

• Exposure to complex mobile journeys across authentication, real-time communication, identity verification and financial services

• High level of technical ownership and influence on application architecture and engineering quality

• Collaborative environment working across product, design, backend, platform and QA teams

• Competitive compensation based on experience
