Lead Solutions Architect (AI/ML Customer Success)

Seldon has spent over a decade pioneering MLOps, helping enterprises deploy, scale, and govern machine learning and large language model systems safely and efficiently. Our mission is to help organizations take control of AI complexity with real-time, cloud-native serving and monitoring that integrate seamlessly into enterprise workflows.

We combine open-source innovation with enterprise-grade capabilities to give teams the flexibility and control they need to move from experimentation to production with confidence.
