In today's world, crime is pervasive and increasingly sophisticated, leveraging both virtual and invisible means. Traditional methods of preventing and investigating crime and terror are no longer sufficient. As technology evolves rapidly, so do the tactics of criminals, and we must keep pace. For nearly three decades, the brilliant minds at Cognyte have collaborated globally to stay ahead of technological and criminal trends, delivering leading investigative analytics software solutions that help make the world a safer place. Our commitment to doing good translates into business success, meaningful work relationships, a can-do attitude, and deep curiosity.

  • Collaborate cross-functionally with development, product, and architecture teams to deliver high-quality solutions.

  • Ensure team adoption of best practices in research, experimentation, and engineering, including reproducibility, scalability, and model governance.

  • Contribute hands-on when needed, designing experiments, writing reusable code, evaluating models, and interpreting results.

  • Take an active leadership role in agile processes, design reviews, brainstorming sessions, and knowledge-sharing forums.

  • Familiarity with GenAI tools and frameworks: LangChain, RAG, vector databases, transformers, vLLM.
