Job Description:

Job Description Job Description About the Role We’re looking for a Generative AI Data Scientist to design, train, and optimize AI models that power next-generation intelligent systems. You’ll work on projects involving large language models (LLMs), NLP, and multimodal data pipelines — helping turn research into production-grade products. Responsibilities - Develop and fine-tune generative AI models (LLMs, diffusion, transformer-based architectures). - Build and manage data pipelines for model training, evaluation, and continuous learning. - Design prompt engineering and retrieval-augmented generation (RAG) frameworks. - Collaborate with engineers and product teams to deploy scalable inference APIs. - Evaluate model performance, bias, and data quality; implement monitoring systems. - Contribute to model interpretability, safety, and responsible AI practices. Qualifications - MS or PhD in Computer Science, Machine Learning, Statistics, or related field. - 3 years of experience in ML/AI, with exposure to generative or transformer-based models. - Strong Python skills (PyTorch, TensorFlow, Hugging Face, LangChain, etc.). - Experience with vector databases, RAG, and fine-tuning open-weight models (e.g., Llama, Mistral). - Familiarity with cloud ML environments (AWS Sagemaker, GCP Vertex, or Azure ML). - Excellent problem-solving and communication skills. Nice to Have - Experience deploying AI systems in production. - Knowledge of multimodal (text, image, audio) model training. - Contributions to open-source AI projects or published research. What We Offer - Competitive compensation - Flexible work environment. - Opportunity to work on frontier AI systems with real-world impact.
