· Collaborate with data engineers, AI engineers, architects, product teams, and business stakeholders to translate requirements into scalable AI solutions.
· Ensure AI solutions follow enterprise security, data governance, responsible AI, and production-readiness standards.
What you need to have to be considered
· 6+ years of experience in Data Science, Machine Learning, AI Engineering, or Advanced Analytics roles.
· Expert knowledge of Exploratory Data Analysis, statistical methods, feature engineering, machine learning algorithms, and model evaluation techniques.
· 3+ years of strong hands-on Machine Learning experience developing and deploying production-grade models.
· Hands-on experience with Generative AI and LLMs, including prompt engineering, RAG, embeddings, vector databases, model tuning, evaluation, and performance optimization.
· Strong proficiency in Python and ML/AI frameworks such as Pandas, NumPy, Scikit-learn, PyTorch, TensorFlow, or equivalent technologies.
· Experience with LLM fine-tuning approaches, model benchmarking, inference optimization, and responsible AI practices.
· Familiarity with AI agents, multi-agent systems, MLOps/LLMOps, model monitoring, and enterprise AI platform architecture.
· Experience with major cloud AI/ML platforms such as Azure, AWS, or GCP and production deployment practices.
