Posted on Nov 24, 2025

As a senior member of the R&D team, you will design, train, optimize, and deploy deep learning models for ShareID’s core products:

Document Verification, Face Authentication, Liveness, and Fraud Detection.

You will work on computer vision problems involving images, videos, and temporal sequences in highly adversarial (fraud-prone) environments.

You will:

  • Design and implement advanced computer vision models, with a focus on:

    • identity document analysis,
    • forgery / tampering detection,
    • face authentication and liveness,
    • deepfake / spoofing attack detection,
    • video-based temporal modeling and tracking.
  • Experiment with state-of-the-art architectures:

    • transformer-based models (ViT, DETR-like, SAM, etc.)
    • diffusion / generative models for augmentation or anomaly detection,
    • latency-optimized networks (quantization, pruning, distillation).
  • Own end-to-end research cycles:

    • literature review,
    • prototyping and experimentation,
    • evaluation on large-scale datasets,
    • productization with engineering teams.
  • Collaborate cross-functionally with Product, Risk, Fraud, and Engineering to bring research ideas into production.

  • Contribute to ShareID’s scientific culture:

    • present papers, lead knowledge-sharing sessions,
    • guide junior ML engineers and interns,
    • optionally participate in benchmarks or publications.
