DevOps Cloud Engineer

We are seeking a DevOps Cloud Engineer to help design deploy and maintain our multi-cloud high-performance computing (HPC) infrastructure. This role will collaborate closely with our managed service partner and our in-house scientific and engineering teams to establish and manage our cloud-based compute environment. Over time this engineer will assume full ownership of our cloud operations automation pipelines and HPC cluster management.

Realta Fusion is a rapidly growing start-up developing compact magnetic mirror fusion energy systems to address the biggest challenge of our time tackling global climate change while ensuring a sufficient energy supply for at least ten billion people on (and off) earth. Realta is targeting the need to decarbonize industrial process heat as the fastest path to full-scale deployment of our technology.We are building a team with diverse talents dedicated to making fusion energy a real solution to humanitys most pressing problem.

Position Responsibilities:

Cloud Infrastructure Development

• Work alongside our managed service provider to deploy and configure Realta Fusions HPC cluster in modern cloud compute environments using scalable virtual networks compute instances and object-storage services.
• Support and manage secure cloud compute infrastructure for export-controlled projects ensuring compliance and data protection.
• Automate provisioning and scaling of HPC resources using Infrastructure-as-Code tools (e.g. Terraform CloudFormation etc.).

System Administration & Operations

• Manage and monitor performance of compute clusters virtual machines and storage solutions.
• Develop and maintain CI/CD pipelines to support simulation software builds and deployments.
• Implement identity management security controls and role-based access across cloud environments.

Software Environment Management

• Install configure and maintain key simulation software such as SolidWorks ANSYS OpenMC and related dependencies.
• Collaborate with scientists and engineers to optimize workloads for cloud-based HPC environments.

Automation & Monitoring

• Build observability tools for resource usage cost management and job scheduling.
• Integrate with container orchestration platforms (e.g. Kubernetes AWS Batch Slurm) for simulation jobs.

Compliance & Governance

• Work with Business Ops Manager and Engineering teams to maintain export control boundaries.
• Document infrastructure designs network architecture and operational procedures.
