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 idóneo 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, and management-plane protection through zero-trust access patterns, bastion hosts, and privileged access controls. You will own the network architecture that separates export-controlled and otherwise sensitive workloads from general-purpose compute, and ensure those controls satisfy the export-control and controlled-information requirements applicable to advanced nuclear technology, working alongside the AI Platform Lead and compliance stakeholders. You will also partner with corporate IT on shared networking and identity infrastructure while maintaining clean boundaries between platform and corporate systems.

Infrastructure as Code and Deployment Automation

Own the infrastructure-as-code for the platform environment, using a declarative and version-controlled toolchain, so that every infrastructure change is version-controlled, reviewed, and reproducible from source. You will build and maintain staging and test environments that mirror production closely enough to catch failures before they reach the live cluster, and implement deployment automation that supports reliable,



auditable releases in coordination with the platform engineers who depend on it.

Reliability, Observability, and Capacity

Define and enforce backup procedures, restore testing cadence, and recovery objectives for the platform, ensuring recovery procedures are documented and verified rather than assumed. You will own the platform observability stack covering metrics, logs, and alerting, building dashboards and alerts that surface problems before they become incidents, and maintain the capacity and cost telemetry for GPU and storage resources that informs infrastructure investment decisions.

You will carry on-call responsibility for the platform infrastructure, respond to incidents with urgency, and conduct blameless post-incident reviews that close the loop on root cause rather than stopping at service restoration.

What We're Looking For

Required Qualifications

- Bachelor's degree in computer science, engineering, or a related technical discipline, or equivalent professional experience.
- 4+ years of professional experience in site reliability engineering, infrastructure engineering, or systems engineering.
- Strong Linux systems administration, networking fundamentals, and firewall and access control list management, with the ability to diagnose a network problem and trace a storage failure independently.
- Production container orchestration experience and demonstrated declarative infrastructure-as-code proficiency.
- Experience operating GPU clusters or comparable high-performance compute infrastructure.
- Hands-on experience with production metrics, logging, and alerting stacks, including building alerts that reflect real failure modes.
- Demonstrated on-call ownership with incident re
