About the Role

We are looking for an expert in biometric recognition and computer vision to help us build a proprietary contactless fingerprint recognition SDK. The core objective is to turn raw images of a hand/finger captured by a smartphone camera into standards-compliant fingerprint templates that can be submitted to government or enterprise APIs for verification. This is not about integrating an existing SDK - we need someone who can architect and deliver the underlying technology.

Responsibilities

• Fingerprint Template Generation: Develop algorithms to extract usable fingerprint templates from camera-based fingerphotos.
• Image Processing Pipeline: Implement preprocessing (segmentation, enhancement, normalization) to make captures usable across lighting, angles, and devices.
• Liveness Detection: Integrate Presentation Attack Detection (PAD) to prevent spoofing, aligned with ISO/IEC 30107-3.
• Standards Compliance: Ensure outputs meet ISO/IEC 19794-2, ANSI/NIST ITL, WSQ formats so they can be recognized by government/enterprise systems.
• SDK/API Delivery: Package the solution into a developer-friendly SDK or API with full documentation, sample code, and integration support.
• Performance & Benchmarking: Test against NIST/NFIQ 2 quality scores and benchmark accuracy, latency, and robustness in real-world conditions.
• Integration Support: Work with mobile developers to integrate into iOS/Android apps and with backend teams for API submission.

Qualifications

• Proven experience building fingerprint or palm recognition algorithms (minutiae extraction, ridge analysis, template generation).
• Strong background in computer vision and image processing (segmentation, denoising, feature extraction).
• Hands-on with OpenCV, TensorFlow, PyTorch, CUDA, and mobile deployment (TensorFlow Lite, Core ML).
• Familiar with biometric standards: ISO/IEC 19794-2, ANSI/NIST ITL, WSQ compression, NFIQ 2 image quality.
• Knowledge of liveness detection / PAD (ISO/IEC 30107-3).
• Track record of building SDKs/APIs with developer documentation and integration support.
• Experience working with secure systems (root of trust, data encryption, secure provisioning) is a plus.
• Advanced degree (MS/PhD) in Computer Vision, Machine Learning, or related field preferred.

What Success Looks Like

• A working SDK/API that can take a smartphone-captured fingerphoto and generate a standards-compliant fingerprint template.
• Templates are accepted by a government verification API and pass quality scoring (NFIQ 2).
• The pipeline is robust to real-world conditions (different devices, lighting, angles).
• Liveness detection is integrated and resilient against common spoofing methods.
• Deliverables include SDK/API, documentation, sample integration code, and performance benchmarks.
