Experience in deploying models using REST APIs, Docker, and cloud platforms such as AWS/GCP/Azure is required. Familiarity with MLOps and version control tools like Git, MLflow, etc., and knowledge of LLMOps platforms such as LangSmith, Weights & Biases will be advantageous. Strong problem-solving skills, attention to detail, and the ability to work in an agile environment are key attributes for this role. A Bachelors or Masters degree in Computer Science, Artificial Intelligence, Data Science, or a related field is preferred.
