Role Overview We are seeking a highly skilled AI Developer with a strong backend and machine learning engineering background to design, train, optimize, and deploy LLM models in on-prem and offline environments. This role is deeply technical and hands-on, requiring expertise across Python ML stacks, model optimization, local inference frameworks, RAG (Retrieval-Augmented Generation) architectures, MCP (Model Context Protocol) integrations, and DevOps workflows tailored for offline systems. You will work closely with our engineering and product teams to build end-to-end LLM pipelines — including data preprocessing, supervised fine-tuning, model quantization, evaluation, RAG pipeline design, and deployment using local or air-gapped infrastructure. If you enjoy working with cutting-edge open-source LLMs, building context-aware AI systems, and designing reliable backend pipelines, this role is for you.

Key Responsibilities Core LLM Development • Train and fine-tune LLMs using supervised fine-tuning (SFT). • Work with open-source models such as LLaMA, Mistral, Qwen, and similar architectures. • Build LoRA / Q-LoRA pipelines for efficient fine-tuning. • Implement and optimize data preprocessing workflows, including tokenization and long-context handling. • Use and extend Hugging Face Transformers & Datasets for training and inference. • Parse and process structured and semi-structured data, including XML/XSD files. • Implement document parsing solutions for Office formats (python-docx, OpenXML). RAG & Context-Aware Systems • Design and implement end-to-end Retrieval-Augmented Generation (RAG) pipelines for document-grounded question answering and knowledge retrieval. • Build and maintain vector stores and embedding pipelines using tools such as FAISS, Chroma, Weaviate, or pgvector. • Optimize retrieval strategies including hybrid search, re-ranking, and chunking approaches tailored for domain-specific corpora. • Develop and maintain MCP (Model Context Protocol) server integrations to enable LLMs to interact dynamically with tools, APIs, and external data sources. • Design agentic workflows that leverage MCP to give models structured access to internal systems and context in a controlled, auditable manner. Offline / On-Prem Model Expertise • Deploy, run, and maintain models fully offline and in air-gapped environments. • Perform model optimization and quantization (GGUF, GPTQ, AWQ, bitsandbytes). • Build and maintain inference systems using frameworks like vLLM, TGI, and Ollama. • Optimize GPU usage (CUDA, cuDNN, VRAM-aware batching). • Maintain local CI/CD pipelines for ML models without cloud dependencies. • Manage local model registries, versioning, and artifacts. • Ensure RAG and MCP components are fully operational in offline and restricted network environments. Backend & DevOps • Build backend services in Python for ML training and inference workflows. • Work with relational databases (Postgres/MySQL) and vector databases for RAG storage layers. • Use Docker and Git for reliable development and deployment pipelines. • Use Azure DevOps for CI/CD, including local runners when applicable.

Requirements Technical Skills • Strong experience in Python for backend and ML development. • Expertise with ML frameworks such as PyTorch or TensorFlow, scikit-learn, and pandas. • Solid knowledge of Postgres or MySQL for data storage. • Experience with Docker, Git, and DevOps best practices. • Hands-on expertise with LLM training, fine-tuning, and optimization. • Experience with Hugging Face Transformers & Datasets. • Familiarity with XML/XSD and Office document parsing tools. • Experience deploying models with vLLM, TGI, or Ollama. • Understanding of quantization techniques (GGUF/GPTQ/AWQ). • Experience working with GPU optimization and the CUDA stack. • Ability to build solutions for offline, on-prem, and air-gapped environments. • Hands-on experience designing and implementing RAG pipelines, including embedding models, vector stores (FAISS, Chroma, Weaviate, or pgvector), and retrieval optimization strategies. • Experience building or integrating MCP (Model Context Protocol) servers to connect LLMs with external tools, APIs, and structured data sources. Nice to Have • Experience building agentic systems using MCP in production or near-production environments. • Familiarity with advanced RAG techniques such as HyDE, re-ranking, or multi-hop retrieval. • Experience managing ML model registries in offline environments. • Familiarity with AWS for hybrid deployments. • Experience with secure environments, restricted networks, or enterprise compliance requirements. Soft Skills • Strong ownership mindset and problem-solving ability. • Ability to work effectively in distributed teams across time zones. • Clear communication when discussing complex technical topics with both technical and non-technical stakeholders.
