  7. Solid understanding of MLOps practices (model versioning, monitoring, CI/CD pipelines).
  8. Strong analytical, problem-solving, and communication skills.
  9. Ability to work in a fast-paced, collaborative environment.

Preferred Qualifications

  1. Master's/PhD in Computer Science, Data Science, AI/ML, Statistics, or a related field.
  2. Experience in GenAI enterprise use cases (chatbots, content generation, code generation, knowledge retrieval).
  3. Knowledge of big data tools (Spark, Databricks, Hadoop) is a plus.
