Senior Data Science - Integrity

Protect millions of buyers and sellers as our Senior Data Scientist for Integrity & Trust. You'll lead building the AI defense systems that detect fraud, eliminate counterfeit products, and maintain marketplace quality across our platform. In MENA's high-COD environment (75% of transactions), trust is everything. Your models will be the difference between platform growth and reputation damage.

• • Build and deploy supervised and unsupervised ML models for policy violation detection, counterfeit detection, and fraud detection.
  • Build and grow the Integrity, Safety & Trust pod, mentor applied data scientists and deliver end-to-end projects with measurable business outcomes.
  • Design feature pipelines that leverage product text, images, seller behavior, and transaction data.
  • Apply NLP models for text classification, entity extraction, and multi-lingual moderation (Arabic + English).
  • Utilize multimodal architectures (CLIP, ViT + BERT) for image–text cross-validation.
  • Develop graph-based and anomaly detection models to identify coordinated or suspicious merchant activity.
  • Collaborate with product, legal, and operations teams to define integrity policies and feedback loops.
  • Implement dashboards and monitoring for real-time detection and escalation (e.g., Elastic, Grafana).
  • Optimize model precision/recall tradeoffs based on enforcement and user experience goals.
  • Familiarity with graph learning, anomaly detection, and multimodal data pipelines.
