About The Position

Nuclearn brings modern AI to the nuclear power industry, focusing on improving the safety and efficiency of operations.

The Customer Success Engineer role involves deploying Nuclearn's AI software within nuclear plants. This technical and customer-facing position requires installing and configuring the platform on customer infrastructure, often in air-gapped environments.
