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, Tensor Flow, Hugging Face, Lang Chain, 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.
