• Build, scale, and maintain Incard’s iOS application using Swift and SwiftUI

• Design and evolve scalable iOS architecture beyond MVP, using modular, feature-based patterns

• Collaborate closely with Product, Backend, iOS and Android teams to deliver high-quality features

• Own performance optimisation, memory management, and stability across the app

• Apply strong product thinking when implementing features — not just engineering execution

• Experience writing unit tests, snapshot tests, and UI tests

• Product-minded engineer with strong attention to detail and edge cases

• Comfortable using AI tools (e.g. Cursor, modern LLMs) to accelerate development responsibly

• Strong communication skills, open to feedback and continuous improvement

• Proactive problem-solver who takes ownership rather than waiting for direction
