Please beware of scammers

As an international platform, Globalplacement is prone to attract those who try to scam people out of their money. For example by promising an internship abroad, but requiring a payment up front for their services. In some cases this might be for legitamite reasons, but always be very very vigilant.

Even though we try our very best to keep our platform free of abuse, we can't garantuee we'll never miss anything. If you see any suspicious vacancies on our website, please do report them by reaching out to us. Never transfer money or share your bank account/credit card details with anyone unless you're absolutely sure it is safe to do so (in which case it is always at your own risk).

Job description

We are seeking a highly motivated AI/ML Intern with a focus on Large Language Models (LLMs) and Retrieval-Augmented Generation (RAG).  You will be working at the frontier of generative AI, helping us explore, build, and optimize systems that bridge the gap between static models and dynamic, private data.

This role is ideal for a student looking for a six(6) month opportunity to apply theoretical knowledge to a production-grade environment and build a significant portfolio piece.

Activities

Architect & Optimize RAG Pipelines: Improve retrieval accuracy using vector databases (e.g., Pinecone, Milvus, or Weaviate).

LLM Implementation: Experiment with and fine-tune prompts and workflows using models like GPT-4, Claude, or Llama 3.

Data Engineering: Assist in the cleaning, chunking, and embedding of proprietary datasets.

Evaluation: Implement benchmarking frameworks to measure hallucinations, faithfulness, and relevancy of model outputs.

Preferred profile

Academic Standing:  Graduate student (Masters/PhD) in Computer Science, Data Science, or a related technical field.

GPA: 3.5 (or equivalent) or higher preferred.

Technical Skills: Proficiency in Python and experience with AI frameworks (e.g., LangChain, LlamaIndex, PyTorch, or TensorFlow).

Domain Knowledge: A solid understanding of transformer architectures and the mechanics of RAG.

Soft Skills: A research-oriented mindset with the ability to troubleshoot complex, non-deterministic systems.
