We are looking for a Senior Solution Architect to own the technical vision and lead an engineering team building a modern data, semantic, and AI platform. You will be the technical authority for how data flows, gains semantic structure, trains models, and powers AI agents — leading a multidisciplinary team (data engineers, ML engineers, semantic/ontology engineers, backend) from design to production.
