Senior Specialist, Digital Reg Docs Tech Lead

Merck Merck · Pharma · Telangana, India

Senior Specialist, Digital Reg Docs Tech Lead at Merck, focusing on developing and integrating Generative AI solutions within R&D enterprise applications. The role involves designing, building, and maintaining production GenAI systems and data pipelines, with a strong emphasis on end-to-end model integration, data engineering, and application development in a regulated healthcare environment. Responsibilities include prompt engineering, fine-tuning, implementing retrieval approaches, building data pipelines, integrating models into applications, and establishing ML Ops workflows, while mentoring team members and ensuring compliance.

What you'd actually do

  1. Design, implement, and maintain generative AI solutions (LLMs, retrieval-augmented generation, embeddings, instruction-following models) to support regulatory document authoring use cases.
  2. Apply prompt engineering, instruction design, template strategies, and fine-tuning/adapter approaches to improve model performance and safety.
  3. Implement retrieval approaches (vector stores, semantic search) and optimize embeddings, index strategies, and relevance tuning.
  4. Build and maintain data pipelines, ETL processes.
  5. Integrate models and AI services into web applications and backend systems (APIs, microservices).
