  • Team8 Cyber Fintech
  • Tel Aviv, Israel
About The Position

We are a stealth startup led by experienced founders, backed by Team8, a leading VC firm,  building AI-powered scam prevention solutions, and we’ve just secured seed funding! 

About the Role:

We are looking for an AI & ML Data Scientist with expertise in LLM fine-tuning, retrieval-augmented generation (RAG), and fraud detection models. This role is ideal for a data scientist passionate about deploying AI at scale, optimizing real-time fraud detection, and integrating advanced ML techniques into cutting-edge security solutions.

Key Responsibilities:

  • Develop and optimize AI-driven fraud models, leveraging LLMs, RAG architectures, and classical ML techniques.
  • Fine-tune large language models (LLMs) to enhance scam detection capabilities in real-time environments.
  • Build scalable, real-time fraud prediction pipelines for anomaly detection and transaction risk scoring.
  • Research and apply graph-based fraud detection techniques and network analysis for identifying fraudulent patterns.
  • Optimize AI models for latency, accuracy, and adaptability in high-volume fraud prevention use cases.
  • Work with data engineers and software engineers to deploy AI models efficiently in production.
  • Stay at the forefront of LLM, NLP, and AI research, implementing the latest advancements in fraud prevention.
Requirements:
  •  5+ years of experience in Data Science, AI, or NLP, preferably in fraud detection, security, or fintech.
  • MSc/PhD in Computer Science, Machine Learning, Mathematics, or a related field.
  • Expertise in Python, Classic ML frameworks, and NLP techniques.
  • Hands-on experience fine-tuning LLMs and/or implementing RAG architectures.
  • Experience deploying AI models in cloud-native environments (GCP/AWS, Kubernetes, or serverless architectures).
  • Strong understanding of graph-based fraud detection, anomaly detection, and adversarial ML techniques.
  • Experience with vector databases (e.g., Pinecone, Weaviate) and AI-driven search (advantageous).

Nice to Have

  • Background in cybersecurity, threat intelligence, or financial crime AI applications.
  • Experience with feature stores, data versioning, and MLOps workflows.
  • Familiarity with federated learning and privacy-preserving AI techniques.

This is a unique opportunity to be at the forefront of AI-driven fraud prevention, leveraging cutting-edge machine learning, LLMs, and real-time detection to combat emerging threats. 🚀
