The Opportunity:

UST is looking for LLM Engineer – On-Prem Deployment & Domain Tuning (Semiconductor Focus)

Key Roles & Responsibilities:

·       Design and implement secure, scalable, and efficient on-premises LLM infrastructure. Integrate LLMs with existing enterprise IT and data systems while maintaining compliance with internal data policies. Collaborate with DevOps to containerize and optimize LLM deployments (Docker, Kubernetes, etc.).

·        Ensure high availability and performance of deployed models. Fine-tune foundation models (e.g., LLaMA, Mistral, Falcon, etc.) using semiconductor-specific datasets.

·       Apply supervised fine-tuning (SFT), reinforcement learning from human feedback (RLHF), and retrieval-augmented generation (RAG) as appropriate.

·       Develop pipelines for domain adaptation using clean, labeled, and structured data from semiconductor sources (e.g., RTL, test benches, datasheets, logs).

Required Skills:

·       LLM Deployment & Tuning: Hands-on experience with deploying open-source LLMs (e.g., LLaMA, Mistral, SemiKong etc) using tools like Ollama, vLLM, or containerized stacks on GPU-based on-prem infrastructure.

·       RAG Implementation: Strong expertise in building Retrieval-Augmented Generation (RAG) pipelines using vector databases such as FAISS, Qdrant, or Weaviate, integrated with tools like LangChain or LlamaIndex.

·       Model Fine-Tuning: Proficiency in instruction tuning, LoRA/QLoRA, or full fine-tuning using frameworks like HuggingFace Transformers, PEFT, and DeepSpeed.

·        Training Data Creation: Proven experience in collecting, curating, cleaning, and annotating domain-specific datasets, including document chunking, prompt engineering, and formatting data for supervised fine-tuning.

·       Evaluation & Benchmarking: Ability to benchmark multiple LLMs (e.g., SemiKong, Falcon, MPT) and quantify performance on tasks like Q&A, summarization, and domain comprehension.

·       Semiconductor Domain Understanding: Working familiarity with semiconductor industry terminology, documents (e.g., datasheets, specs), or workflows is highly desirable.

·       GPU & Infra Proficiency: Solid understanding of CUDA, PyTorch, model parallelism, and performance optimization on multi-GPU environments.

·       Proficient in Python, Git, and containerization (Docker) Desired Skills:

·        Experience with Kubernetes or MLOps is a bonus.

Qualification:

·       BTech in Computer Science · 3 to 6 Years of experience.
