iOS Developer

We are looking for a Senior iOS Engineer to design and develop high-traffic iOS applications in the context of digital banking, supporting critical experiences such as payments, benefits, cashback, and financial management. This role will have a direct impact on the product quality, performance, security, and architectural evolution of the app.

Responsibilities (Expected Experience)

• Design and develop high-traffic iOS applications for digital banking, supporting critical experiences such as payments, benefits, cashback, and financial management.

• Develop advanced interfaces with UIKit (and soon SwiftUI), optimizing performance, rendering, and compatibility with multiple iOS versions.
• Integrate backend services using REST/URLSession, ensuring robustness against errors, timeouts, and adverse network conditions.
• Manage the state and lifecycle of views in UIKit, avoiding memory leaks and retention issues (closures, delegates, observers).
• Implement banking-grade security mechanisms: Keychain, biometrics, certificate pinning, and protection against MITM.
• Optimize performance and resource consumption (CPU, memory, network), ensuring a smooth experience even on demanding devices.
• Develop and integrate front agents with Kiro in the iOS app, enabling conversational experiences, smart recommendations, and journey automation on the front end, focusing on UX, performance, and compliance.
