Key Responsibilities
- Advanced Prompt Engineering: Create, test, and refine sophisticated prompts for LLMs, applying techniques such as few-shot learning, chain-of-thought, and self-consistency.
- RAG Systems (Retrieval-Augmented Generation): Design data pipelines, implement embeddings, and optimize retrieval mechanisms integrated with generative models.
- LLM Security: Develop strategies against adversarial attacks (prompt injection, jailbreaking), ensuring input sanitization and output validation.
- Chatbot Development: Build and maintain intelligent virtual assistants using platforms like Google Dialogflow, integrating them with APIs and backend systems.
- NLP and ML Models: Apply advanced NLP techniques, fine-tune pre-trained models (BERT, GPT, T5), and implement MLOps practices for production deployment.
Qualifications & Technical Skills:
- Proven experience with LLMs, NLP, and Prompt Engineering.
- Knowledge of RAG Systems, vector databases (Pinecone, FAISS, Weaviate), and data pipelines.
- Familiarity with AI security and vulnerability mitigation.
- Experience with chatbot platforms (Dialogflow CX/ES) and API integration.
- Proficiency in Python and libraries such as Hugging Face, LangChain, and Transformers.
- Knowledge of MLOps and scalable deployment practices.
- Technical English proficiency for reading research papers and documentation.
Nice To Have Skills
- Experience with serverless architectures (AWS Lambda, API Gateway).
- Knowledge of vector databases and semantic search optimization.
- Participation in projects involving AI security and adversarial attack mitigation.
