About the role
We’re looking for a Platform Engineer to help build an enterprise AI platform for a global enterprise client.

AI Platform Engineering & Operations

Deploy and operate supporting services for LLM applications: model gateways, vector databases, tracing, and evaluation
•
Support GPU workloads, including node pools, scheduling, and cost monitoring
•
Write runbooks and automate day-two operations
AI Engineering
•
Build reference agents and LLM application templates that client teams can start from
•
Help application teams integrate with the platform and debug their workloads
•
Prototype with agent frameworks and LLM APIs to test what the platform needs to support
