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 humanity’s most pressing problem. 

Position Responsibilities: 

Cloud Infrastructure Development 

• Work alongside our managed service provider to deploy and configure Realta Fusion’s 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. 

Qualifications 

Required: 

• 5+ years of experience in DevOps, Cloud Infrastructure, or Systems Engineering roles. 
• Proven experience managing cloud-based compute environments using VPCs, EC2-like compute instances, S3-style object storage, and container orchestration platforms 
• Proficiency in scripting and automation (C/C++, Python, Bash, PowerShell, PHP/SQL).
• Experience in managing JupyterHub or similar multi-user environments.
• Knowledge of HPC systems, parallel computing, and simulation software environments. 
• Familiarity deploying and managing workloads across large-scale cloud environments with capabilities such as virtual networking, resource grouping, object/blob storage, and identity management services. 
• Exposure to IaC tools such as Terraform, Ansible, or CloudFormation. 
• Understanding of networking, VPNs, and secure data exchange between cloud and on-prem environments. 

Preferred

• Experience working with export-controlled or regulated data environments. 
• Familiarity with CAD/CAE software support (SolidWorks, ANSYS). 
• Knowledge of container orchestration, CI/CD, and HPC schedulers (Slurm, PBS, etc.). 

 Compensation & Benefits 

What we are working on is hard… and hugely important. Realta Fusion is assembling a talented team bound together by a passion to solve humanity’s biggest challenge with first-of-a-kind technology.  Additionally, Realta offers:  

• Competitive compensation package, including equity stock options. 
• Comprehensive benefits including health, dental, and vision insurance, plus a retirement savings plan. 
• Flexible paid time off (PTO) to support work-life balance. 
• Work and live in Madison, Wisconsin — one of America’s most livable and vibrant cities. 

We value diversity as a critical factor in innovation and believe a diverse team is necessary to solve the toughest problems. We aim to create an inclusive environment that unleashes the full creativity of our team members from a wide variety of backgrounds and experiences. We provide equal employment opportunities to all individuals based on merit and without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, veteran status, or any other protected status under applicable laws.
