Remote Natural Language Processing Engineer Jobs in California

We are seeking a high-impact, visionary Senior Principal AI Engineer to architect, design, and oversee the next generation of our enterprise hardware intelligence platform. In this role, you will be the change agent across our global R&D organization, bridging the gap between advanced Generative AI and complex hardware engineering. Reporting into the Office of the VP of Engineering, you will spearhead the technical development of our "Celestica-Tuned Enterprise LLM," transforming massive, highly complex repositories of global engineering data into active, predictive, and autonomous design intelligence.

This is a high impact, high visibility technology role. You will serve as the lead and technical authority responsible for building the domain-specific data pipelines and architecting the cutting-edge Topological and Spatial Retrieval-Augmented Generation (RAG) frameworks. Your mission is to develop a secure, multi-agent AI system and build a digital twin of the hardware design process, enabling real-time simulation and predictive analysis of board performance. This system enables engineering teams to interact natively with design tools and legacy knowledge. Working closely with hardware Subject Matter Experts (SMEs), you will translate schematics, layouts, board logs, and multi-tool diagrams into an intelligent platform that our designers use daily to eliminate board spins, automate compliance, and drastically accelerate time-to-market.

• Drive Strategic AI Implementation: Set the technical standard for secure LLM applications within Celestica, utilizing advanced proprietary data and secure infrastructure to build a highly reliable, zero-hallucination platform for high-stakes engineering.
• Develop Digital Twin Capabilities: Architect and integrate digital twin models to simulate and validate physical hardware performance, enabling virtual prototyping and early design cycle optimization.
• Architect & Code the Platform: Act as the primary hands-on developer to design, build, and deploy a multi-database, topology-aware RAG system capable of accurately vectorizing complex hardware design data.
• Build End-to-End AI Pipelines: Create specialized parsers and ingestion pipelines that translate dense binary files, netlists, and graphical schematics into high-dimensional graph-based semantic embeddings.
• Develop Multi-Agent Orchestrations: Leverage advanced orchestration frameworks and the Model Context Protocol (MCP) to develop autonomous AI agents that can manage multi-tool workflows across synthesis, physical placement, and manufacturing sign-off.
• Integrate Cross-Domain Data: Engineer data lakes that seamlessly correlate unstructured text (supply chain metadata, manufacturing datasheets, standard compliance checks) with physical engineering physics (layout geometries, pin connectivity).
• Collaborate with Hardware SMEs: Work side-by-side with Principal Hardware, SI/PI, and Thermal Engineers to encode deep domain expertise, design rules, and hardware guardrails directly into the AI system's "Agent Skills."
