Job Type: Full-time (WFO)

Experience Required: ~1.5 Years

Qualifications

• Bachelor's or Master’s degree in Computer Science, Machine Learning, AI, or a related field.
• Candidates with relevant project experience or certifications in NLP/ML will also be considered.

Responsibilities

• Assist in fine-tuning and deploying LLMs using transformer-based architectures (e.g., BERT, GPT, LLaMA).
• Contribute to the development of simple autonomous agents or chatbots using open-source tools.
• Support integration of vector databases (like FAISS or Milvus) for semantic search and memory storage.
• Work on LLM inference and basic optimization under guidance (e.g., batch inference, prompt tuning).
• Collaborate with the team on RAG pipelines and learn to integrate retrieval mechanisms into LLM workflows.
• Stay up to date with basic advancements in LLMs and NLP tools.
