Original thinking, deep technical rigor, intellectual agility, and exceptional problem-solving are essential.

Responsibilities:

  • Lead end-to-end Data Science initiatives from problem framing through validation, CI/CD-based production deployment, monitoring, and ongoing operational optimization of AI systems
  • Develop advanced ML capabilities, including predictive modeling, anomaly detection, classification, and behavioral analysis
  • Develop the intelligent capabilities behind security AI agents, combining machine learning, LLMs, statistical methods, and domain-specific algorithms, with a strong understanding of how agents use these capabilities within multi-step workflows
  • Adapt and fine-tune LLM technologies for domain-specific security use cases
  • Define and implement rigorous evaluation methodologies for ML and agentic AI systems, including decision quality, reliability, robustness, uncertainty, and failure modes
  • Partner with Product, Engineering, and Security teams to deliver measurable business impact
  • Provide technical leadership and mentorship across multidisciplinary Data Science initiatives

Requirements:

  • M.Sc. in Data Science, Computer Science, Statistics, Mathematics, or a related quantitative discipline
  • At least 7 years of hands-on Data Science experience, delivering end-to-end solutions into production environments
  • Deep understanding of machine learning theory, statistical reasoning, and practical model behavior
  • Strong expertise in Python and the modern Data Science ecosystem (NumPy, Pandas, Scikit-learn, PyTorch / TensorFlow, etc.)
  • Strong understanding of LLM architectures, adaptation and fine-tuning methodologies
  • Strong understanding of AI agent architectures and concepts, including tool use, context management, memory, planning/reasoning, and multi-step workflows
  • Strong analytical rigor and structured problem-solving capability
  • Excellent interpersonal skills and proven ability to work within multidisciplinary product teams

Advantage:

  • Experience developing or deploying AI agents or multi-step reasoning systems
  • Experience with local/on-premise AI systems, particularly under constrained compute, memory, latency, or security requirements
  • Experience with small language models (SLMs), model quantization, distillation, efficient inference, or other techniques for running AI models locally
  • Experience with Generative AI, RAG, GraphRAG, semantic search, vector databases, or domain-specific LLM adaptation
  • Experience with ML/AI observability, model monitoring, or drift detection
  • Experience with graph technologies, such as Neo4j
  • Background in network security, firewall policies, or compliance analytics
