Cloud Infrastructure Support Engineer

Job Summary:

We are seeking a highly skilled Cloud Infrastructure Support Engineer to join our global Customer Support team. The primary goal of this team is to delight our customers worldwide by ensuring that any incident related to Radiant’s Cloud Platform, High Performance Computing (HPC), and AI supercomputer fleet (some of the fastest machines in the world) is resolved swiftly and decisively in collaboration with our engineering teams and third-party suppliers.

The Support team delivers 24/7, 365 on-call support using a “follow the sun” model to handle and resolve customer queries. As a Cloud Support Engineer, you will be a hands-on technical contributor, responsible for triaging, diagnosing, and resolving complex infrastructure issues while providing an exceptional customer experience.

Past HPC or AI experience is not required. However, this role requires a strong background in customer-facing technical support, solid IT infrastructure fundamentals, and a desire to grow expertise in next-generation HPC and AI technologies such as GPUs, InfiniBand, parallel storage, and AI orchestration software.

This is an excellent opportunity for an experienced support engineer to enter the AI infrastructure space and develop cutting-edge technical skills in a fast-growing industry.
