About the Role :
We're seeking a seasoned Lead Data Scientist to lead NLP/ML research efforts and architect end-to-end solutions.
You will be instrumental in driving innovation, mentoring junior team members, and working closely with stakeholders to align AI capabilities with strategic goals.
Key Responsibilities :
- Lead the development and deployment of production-grade NLP and ML models.
- Work with large language models (LLMs), RoBERTa, GPT APIs, and hybrid architectures.
- Guide and review the work of junior scientists and interns.
- Develop pipelines for training, evaluation, and continuous model monitoring.
- Collaborate with cross-functional teams to scope new projects and define success metrics.
- Write technical papers, PoCs, and support patentable innovations when applicable.
Required Skills :
- 5+ Years of relevant experience along with prior exposure to team leadership responsibilities.
- 5+ Years of deep knowledge of modern NLP architectures (transformers, LLMs, embeddings).
- Design, build, and deploy Generative AI models (e.g., LLMs, Diffusion Models) into production systems.
- Strong understanding of Neural Networks, Transformer models (e.g., BERT, GPT), and deep learning frameworks (e.g., TensorFlow, PyTorch).
- Proficiency in Python and ML libraries (e.g., Scikit-learn, Hugging Face, Keras, OpenCV).
- Proficiency in data pipelines, MLOps, model versioning, and evaluation frameworks.
- Ability to distill complex problems and explain them clearly to technical and non-technical audiences.
Preferred Qualifications :
- Published work in conferences/journals or experience contributing to open-source projects.
- Familiarity with vector databases (Pinecone, FAISS), LangChain, or prompt engineering.
- Experience in managing research interns or small AI/ML teams.
Education :
- Master's or PhD in Computer Science, Machine Learning, or a related field.
