Senior Mobile iOS Engineer

As deepfakes and synthetic identities become mainstream, protecting personal identity has never been more challenging. At Microblink, we’re building the biometric infrastructure to meet that challenge—and we’re looking for a Senior iOS Engineer to help lead the way.

As part of our Biometrics team, you’ll take ownership of our iOS SDK development, working alongside backend, ML, product, and security experts to build seamless connections between iOS apps and our identity verification systems. Your work will enable customers to embed advanced fraud prevention tools into their apps easily, reliably, and at scale.

We’re looking for an experienced iOS developer with a strong foundation in native development and the curiosity to work across layers, including occasional C++ integration. You’ll help architect high-performance SDKs from the ground up and contribute to launching innovative identity products that protect millions of users worldwide.

If you're passionate about iOS and care deeply about building technology that safeguards people’s identities, we’d love to hear from you.
