• Designing and developing NLP solutions using techniques such as text classification, NER, topic modeling, and text generation.
• Collaborating with data engineers and MLOps teams to ensure clean data pipelines and seamless model integration.
• Applying LLMs (e.g., GPT, BERT, LLaMA2) and knowledge graphs to enhance natural language understanding and reasoning.
• Conducting exploratory data analysis and developing robust pre-processing strategies for unstructured text.
• Evaluating NLP models, algorithms, and architectures to recommend optimal solutions.
• Communicating insights through reports, visualizations, and presentations for both technical and non-technical audiences.
• Mentoring junior team members and staying current with advances in NLP, LLMs, and GenAI.

• A Bachelor\'s or Master\'s degree in Computer Science, Data Science, or a related field (or equivalent combination of education and experience).
• Proven experience as a Data Scientist with a strong focus on NLP and knowledge graphs.
• Practical experience with graph machine learning techniques such as graph neural networks and graph data science.
• Proficiency in Python and experience with key NLP libraries and frameworks (e.g., NLTK, spaCy, Transformers, Hugging Face, BERT, Langchain).
• Hands-on experience with deep learning frameworks like TensorFlow or PyTorch.
• Strong problem-solving skills, particularly in addressing complex NLP challenges.
• Excellent communication and collaboration skills, with the ability to work effectively in cross-functional teams.
