• implementing secure authentication and integration flows between the native application container and external services,
• optimizing application performance, stability and memory efficiency,
• ensuring that newly developed components meet the required performance, stability and quality benchmarks,

Your profile:

• advanced knowledge of the Swift programming language and Apple's iOS SDK,
• strong experience building interfaces using modern frameworks like SwiftUI (and older structures like UIKit),
• strong comprehension of mobile security, networking (REST, JSON), and bridging sessions safely between native views and third-party web portals,
• a track record of shipping and maintaining performance-optimized native applications,
• 4+ years of commercial experience in iOS development,
• good understanding of the iOS SDK and iOS application architecture (MVVM / Clean Architecture),
• experience writing unit tests and E2E/UI tests,
• commitment to code quality through code review and TDD,
• experience with Xcode, Swift Package Manager / CocoaPods, and modern iOS development tools,
• experience publishing apps to the App Store,
• practical experience using AI-powered assistants (e.g. Claude Code, GitHub Copilot, Cursor) to improve productivity, quality, or decision-making in software delivery.

Work from the European Union region and a work permit are required.

Nice to have:

Experience applying GenAI in a more structured way within the SDLC, including defined workflows, prompt patterns, or tool integrations embedded into daily work.

• Interest in and familiarity with emerging AI-driven practices (e.g. agent-based workflows, automation patterns, AI-augmented development), with a willingness to explore and experiment beyond standard approaches.
