AI Architect - Foundation Models

AI Architect - Foundation Models(Full-time, onsite in El Segundo, CA - U.S. citizenship required due to the nature of our work)About CambiumCambium is an advanced materials startup building next generation polymer and composite systems for aerospace, defense, and critical industries. We combine physics-based modeling, experimentation, and cutting-edge AI-including multimodal foundation models-to accelerate materials discovery and deployment.Role SummaryWe are looking for a senior AI Architect to own the technical direction, architecture, and hands-on development of Cambium's multimodal polymer/materials foundation models, including their augmentation with frontier LLMs and general science AI models developed by collaborators.This role is responsible for building up Cambium's foundational AI capabilities used in advanced material design, rapid product development, and manufacturing. You will push the envelope on generative AI models that integrate chemistry, physics, structure, and process data, and scientific knowledge - while honing them in real-world R&D and manufacturing environments.This role is ideal for someone who wants to build full stack AI-from deep model design to experimental data ingestion pipelines to live deployment-without bureaucracy or silos.Key Responsibilities• Own Cambium's foundation model architecture and long-term technical direction.• Design multimodal models combining molecular, physical, experimental, and knowledge data.• Define and implement workflows for continuous training, development, and benchmarking.• Lead scaling strategy for distributed training and cloud compute (GCP and/or Azure).• Collaborate closely with the AI team, materials scientists, product engineers, and operations.Qualifications• Deep experience (7+ years) designing and training large scale neural network models (multimodal, scientific, or foundation models).• 10+ years in industry in a software, data science, or related role.• Expert in model training, distributed training, ML systems, and model infrastructure.• Ability to translate ambiguous scientific and operational problems into model driven solutions.• Experience working across data, engineering, scientific, and/or business operational teamPreferred• Experience in large scale chemical synthesis laboratories• CIH, CSP, CHMM, or similar certification• Experience implementing EHS management systems (ISO 14001 / ISO 45001)BenefitsCambium offers a highly competitive compensation and benefits plan.This includes excellent medical/dental/vision benefits, and a matching 401(k) plan.
