Descripción de la vacante

Meitner Energy seeks a Site Reliability/Infrastructure Engineer to own the GPU cluster and security boundary for its regulated nuclear AI platform. You will operate bare-metal GPU infrastructure, enforce zero-trust access, and manage deployment automation with IaC, staging, and incident response.

You'll collaborate with the AI Platform Lead and corporate IT, build observable systems, and maintain backups, capacity, and cost telemetry. This role is based in Dallas and requires on-site presence.

Formación

• 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 response and post‑incident review practice, including verified restore testing rather than backup reports alone.
• Experience implementing network segmentation, default‑deny policies, and privileged access controls in a production environment, and the ability to work on‑site in Dallas.

Responsabilidades

• 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.
• 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.
• 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.
