[CIS] Senior iOS Software Engineer

Project – the aim you’ll have
This project is for a global leader in medical and travel security risk services, helping organisations protect their people wherever they work and travel. You’ll join a dedicated mobile team rebuilding the client’s traveller-facing apps, part of the Subscriber Portal, as fully native iOS and Android applications to replace the existing React Native versions. Travellers and expatriates use these apps to receive location-based medical and security alerts, access country risk information, check in, and contact 24/7 assistance centres with a single tap. The backend is already in place, allowing the team to focus on building a fast, secure and accessible native experience. When someone faces a crisis abroad, the app needs to work reliably when it matters most.

Role – how you’ll contribute​​​​​​​

• Develop and maintain the native iOS application using the latest Swift and SwiftUI. Write clean, scalable, and well-documented code;
• Collaborate with product managers, backend developers, designers, and other stakeholders on requirements review, suggest solutions and estimate efforts to build user-friendly applications;
