iOS Engineer
ABOUT THE ROLE
Mobile is the front door to the Q-ID. Every authentication, whether it’s a customs officer scanning a tax stamp, a partner embedding Q-ID verification into their own app, or a consumer checking a product is genuine, happens on a smartphone. These authentications happen in variable real-world conditions, on a wide range of devices.
The iOS Engineer will be responsible for productising research and development outputs, creating a robust and well-engineered app and SDK. They will bring skills across:
- Native iOS (Swift, SwiftUI, AVFoundation, Core ML, Vision)
- Mobile SDK distribution, for partners embedding Q-ID into their own apps
- Cross-platform integrations like.NET MAUI, React Native, and Flutter
- Integration with our AWS verification APIs
This is an exciting opportunity for someone who is looking to progress in their career and translate cutting-edge scientific research into a tangible, real-world product.
Ideal for a strong early-career or mid-level engineer who wants to grow into deep mobile product ownership.
