About this role

BrightAI is searching for a Senior AI Engineer specializing in LLMs and RAG to design advanced retrieval-augmented generation systems in Palo Alto, California. This role suits an experienced machine learning professional ready to transform industrial operations through conversational AI.

Role Overview

The Senior AI Engineer will spearhead the creation of Retrieval-Augmented Generation architectures that merge large language models with real-world knowledge repositories. Operating at the intersection of natural language processing, foundational models, and real-time systems, this position builds intelligent assistants to guide operators and technicians through complex industrial troubleshooting. The professional in this role collaborates closely with product, data, and cloud departments to engineer scalable, privacy-conscious, and low-latency artificial intelligence applications.

Key Responsibilities

Architect and build comprehensive RAG pipelines that integrate models like GPT, Claude, Mistral, and LLAMA with external structured and unstructured data sources.
Create AI assistants designed to help technicians diagnose and solve equipment anomalies within industrial, plant, and factory environments.
Construct data ingestion, preprocessing, and indexing pipelines for massive document libraries, enabling precise semantic search and grounding.
Fine-tune and customize foundational models to reflect domain-specific language and industrial logic.
Establish evaluation frameworks to track system performance, production accuracy, and overall user experience.
Research current breakthroughs in retrieval methods, prompt engineering, and LLM structures for integration into the product roadmap.

Requirements

Hold an M.S. or Ph.D. in Artificial Intelligence, Computer Science, Machine Learning, or a closely related discipline, with a focus on deep learning or NLP.
Bring five or more years of machine learning or artificial intelligence experience centered on conversational AI, LLMs, or natural language processing.
Demonstrate proficiency with modern foundational models, open-source models, prompt engineering, and instruction tuning.
Possess proven experience building RAG pipelines using custom vector stores or frameworks like LangChain, including at least one production-grade system launch.
Understand document retrieval principles thoroughly, covering semantic search, embedding creation, similarity metrics, and vector databases like Pinecone, Weaviate, or FAISS.
Maintain a strong grounding in core machine learning techniques, such as reinforcement learning or decision-making models.
Exhibit robust Python programming capabilities and familiarity with development frameworks including PyTorch and Hugging Face Transformers.
Show a track record of embedding artificial intelligence into user-facing real-world applications under operational constraints.

Nice to Have

Experience with agentic RAG systems.
Background applying large language models within physical infrastructure or industrial domains like manufacturing, utilities, energy, or logistics.
Familiarity with maintenance workflows, industrial control systems, or technician assistance processes.
Exposure to multimodal models or combining text with time-series and sensor data.
Prior startup or fast-paced environment experience developing LLM products from the beginning.
