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.

Small mobile improvements (e.g., scan speed, false-reject rate, camera handling) have an outsized commercial impact and are often the difference between winning and losing a customer.
