• Global OCR & ID Understanding – Create scalable OCR and document‑parsing pipelines for passports, driver’s licenses, and national IDs across multiple languages.
• AIGC for Image & Video Generation – Exploring generative AI (diffusion/transformer models) for synthetic data creation, media augmentation, and visual manipulation.
• Multi‑Modality Security – Leveraging a combination of images, videos, and user behaviors to enhance security through cross‑modal AI techniques.

The ideal candidate will contribute to the development of innovative solutions to safeguard biometric processing systems and enhance security across multiple AI‑driven applications.

What You’ll Be Doing

• Design, train, and deploy state‑of‑the‑art deep‑learning models for computer vision, multimodal fusion, and AI agent applications.
• Develop production‑ready pipelines for OCR text extraction, biometric matching, fraud pattern recognition, and AIGC generation.
• Collaborate with backend, product, and infrastructure teams to integrate AI solutions seamlessly into large‑scale systems with high availability and low latency.
• Drive experimentation and R&D in vision‑LLM and multimodal representation learning to advance AI security capabilities.
• Stay current with academic and industry advances in deep learning, AI agents, and generative security technologies, and translate them into practical solutions.
• Contribute to internal knowledge sharing and mentor junior engineers in applied AI development best practices.

What We Look For In You

Bachelor’s degree (or higher) in Computer Science, Electrical Engineering, or a related field, with a focus on computer vision, deep learning, and multimodal.

8+ years of hands‑on experience developing AI/ML solutions in areas such as computer vision, AI agents, multimodal learning, vision‑LLM, or generative video/image modeling.

Proficiency in deep learning frameworks such as TensorFlow, PyTorch, or OpenCV.

Strong analytical and problem‑solving skills.

Nice to Haves
