Senior iOS Developer

We're building a native iOS SDK that brings Xident's "Verify Once" experience to mobile apps. You'll create a production-grade Swift SDK with camera-based liveness detection, on-device age classification via Core ML, and seamless document capture — all running privately on-device.

Xident is building the future of digital identity verification. Our platform enables businesses to verify users' ages and identities in seconds, while respecting privacy through our unique "Verify Once, Access Everywhere" model.

Founded in 2023, we've already processed over 10M+ verifications processed and serve 500+ businesses. We're a remote-first company with team members across 12 countries.

Our mission is simple:
To make identity verification seamless, private, and accessible for everyone. We believe privacy and convenience shouldn't be mutually exclusive, and we're proving it every day.
