About Meitner Energy
Meitner Energy is developing advanced nuclear energy solutions intended to deliver reliable, scalable, and carbon-free electricity for industrial and grid applications.
Our international team brings together nuclear, engineering, commercial, regulatory, and project-development experience. We are building an organization focused on disciplined engineering, responsible execution, and the deployment of nuclear energy at meaningful scale.

The Opportunity
Meitner’s AI platform runs on infrastructure that has to be right, and this role owns it. You will operate the bare-metal GPU cluster, the private networking and storage beneath it, and the compliance boundary that keeps regulated nuclear material separated from general-purpose workloads. You will also own the deployment automation and staging environments that other platform engineers rely on to ship reliably, which makes this the layer everything else is built on.
The work rewards someone who treats uptime and security posture as fixed requirements,



can implement a default-deny network architecture and explain every exception in it, and has the discipline to automate and document rather than carry the environment in their head. You will work directly with the AI Platform Lead and partner with corporate IT on shared networking and identity where that makes sense.
This role is adecuado for someone who:
• Takes personal ownership of uptime and treats incidents as failures of process rather than bad luck.
• Builds infrastructure through code and automation instead of one-off manual changes.
• Is comfortable in regulated, security-conscious environments where the network boundary is a hard requirement.
• Wants to be the person the rest of the engineering team relies on when the cluster is the constraint.

What You'll Do
Cluster Operations and Security Boundaries
Operate and maintain the GPU cluster serving both the regulated and the non-regulated tiers, enforcing default-deny egress, network segmentation
