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.

This is a hands‑on leadership role. You will set architecture direction, define the contracts between data, semantic, and AI layers, write the patterns the team builds against, and stay close enough to the code to debug a data transform, a GraphQL/policy path, or an agent flow.

• Own the end‑to‑end architecture of the data → semantic → AI stack and the contracts between layers (GraphQL, REST, protobuf, event streams, tool‑calling interfaces).
