  • MLOps & Deployment: Docker, Kubernetes, CI/CD pipelines
  • Mathematical & Statistical Skills: Probability, Linear Algebra, Optimization
  • Deep Learning & Neural Networks: CNN, RNN, Transformers, GANs

Good-to-Have Skills:

  • Experience with vector databases (FAISS, Pinecone, Weaviate) for AI search and retrieval.
  • Hands-on experience with AutoML tools like H2O.ai, Google AutoML, or DataRobot.
  • Familiarity with reinforcement learning and multi-agent systems.
  • Exposure to AI ethics, model interpretability, and explainable AI (XAI).
  • Knowledge of Graph Neural Networks (GNNs) and Knowledge Graphs.

Education & Experience:

  • Bachelor's/Masters degree in Computer Science, Data Science, AI/ML, Mathematics, or a related field.
  • 4-7 years of hands-on experience in AI/ML, cognitive computing, and NLP.

Why Join Us?

  • Work on cutting-edge AI projects with a team of experts.
  • Opportunity to develop and deploy generative AI models for real-world applications.

If you're passionate about cognitive AI, Abuse Management, LLMs, fraud detection, and data science, apply now!
