We are looking for a high-impact Principal AI Engineer to architect, design, and code the next generation of our engineering intelligence platform. In this role, you will bridge the gap between advanced Generative AI and complex hardware engineering. Reporting to the Office of the VP of Engineering, you will lead the technical development of our "Celestica-tuned Enterprise LLM," transforming massive repositories of global engineering data into active, predictive intelligence.

This is a
hands-on development role
. You will be the lead developer responsible for building the data pipelines, RAG architectures, and multimodal models that allow our engineers to "talk" to their design tools and legacy data. You will work closely with hardware Subject Matter Experts (SMEs) to transform schematics, logs, and diagrams into a high-performance tool that our designers use daily to reduce board spins and accelerate time-to-market.
