Principal Scientist - Generative AI

Description
Role : Principal Scientist (AI, ML & Generative AI)
Location : Bangalore
Experience : 10 - 15 Years
Job Summary
We are seeking a visionary Principal Scientist to lead our Artificial Intelligence research and implementation strategy. In this role, you will bridge the gap between cutting-edge academic research and large-scale industrial application. You will be the technical authority for our Generative AI roadmap, overseeing the development of LLMs, multimodal systems, and agentic workflows that solve complex, real-world problems.
Responsibilities

• Technical Leadership : Drive the long-term R&D roadmap for AI/ML, focusing on Generative AI, LLMs, and Multimodal models.
• Model Innovation : Lead the end-to-end lifecycle of large-scale model training - from data curation and pre-training to fine-tuning (SFT, RLHF) and optimization for production.
• 
  Architectural Oversight : Design robust, scalable system architectures including RAG pipelines, vector databases, and autonomous agentic frameworks.
• Research & Publication : Maintain the companys technical edge by publishing original research in top-tier venues (e.g., NeurIPS, ICML, ICLR, CVPR) and patenting novel methodologies.
• Strategic Collaboration : Partner with Product and Engineering leadership to translate business requirements into high-impact AI solutions.
• Mentorship : Act as a force multiplier by mentoring Staff and Senior Scientists, fostering a culture of technical excellence and continuous learning.
  

Required Qualifications
