Senior Applied AI Engineer - Production Systems & Cloud

EY is seeking an Applied AI Engineer to own the AI stack end-to-end—from cloud infrastructure it runs on, through the model layer, to the systems that keep it in production. This builder role alternates between solo delivery and small-team leadership as projects demand.

You’ll work across frontier APIs and open‑source models, deploying, fine‑tuning, and operating them on cost‑aware, secure cloud platforms at scale.
