The National Academic Infrastructure for Supercomputing in Sweden (NAISS) operates large-scale parallel computing systems and data storage systems. We offer training in the use of high performance computing (HPC), provide user support/helpdesk services, and collaborate directly with research and development projects within the HPC domain. Our goal is to provide Sweden’s most attractive research environment for scientific fields that rely on large-scale computing and other e-science. Our systems are available 24/7. At the supercomputing center, several major computing and storage systems are operated. Examples include the national AI supercomputer Berzelius, dedicated to large-scale research in artificial intelligence and machine learning, and Arrhenius, Sweden’s largest academic HPC resource. These systems are used by researchers across Sweden and support advanced GPU‑accelerated workloads, distributed training, and data‑intensive AI workflows. Some of the systems are also part of EuroHPC and are used by researchers throughout Europe. As demand continues to grow in both scale and complexity, we are now expanding the systems group to strengthen system reliability, usability, and user‑focused services.

About the position

At NAISS, you will be part of a small systems team of 2–6 people responsible for the design, deployment, operation, and continuous development of a computing system throughout its entire lifecycle. The team builds, installs, tests, documents, monitors, and maintains the cluster and its associated storage and software environment. You will also contribute to the development and maintenance of internally developed software components and automation tools used in daily operations.

The systems team works largely independently. As a result, you will have a high degree of personal responsibility and be actively involved in decisions regarding system design, architectural improvements, and operational planning. The role also involves close collaboration with users through helpdesk support and direct dialogue with research groups, ensuring that the systems evolve in line with emerging needs in HPC, AI, and machine learning.

About you

To succeed in this role, the following qualifications are required:

• A relevant university degree in IT or Computer Science (e.g. information systems or computer engineering), or equivalent competence.
• Experience in Linux system administration.
• As most user support and documentation are conducted in English, you must be able to communicate clearly both in writing and orally in English and Swedish
• Experience with at least one of the programming languages we use (Python, Bash, C, Ruby, Lua)

The following qualifications are also considered advantageous:

• Experience in team leadership, project management, or task coordination
• Experience deploying and maintaining web‑based HPC access solutions (e.g., Open OnDemand)
• Experience with virtualization solutions (Proxmox, VMware, or similar)
• Experience with configuration management (Puppet/OpenVox, Ansible, or similar)
• Experience with version control systems (Git or similar)
• Experience with logging and monitoring systems.

Additional qualifications that strengthen your application include one or more of the following:

• A master’s degree in computer science and engineering, computer science, or a related field
• Experience with cloud technologies for large-scale containerization (OpenNebula, OpenStack, Kubernetes, or similar)
• Experience with system administration in large-scale environments (compute clusters or cloud services)
• Experience in direct user support or helpdesk work
• Experience with scientific simulations or data analysis (HPC workloads or machine learning)

You need to be independent, responsible, detail‑oriented, and well‑structured to function effectively within the group, while also being sociable and possessing strong collaboration skills. You will work with state‑of‑the‑art technologies and specially developed solutions, where creativity and strong problem‑solving abilities are important assets.

The workplace

Operations teams at NAISS are organized by functional areas. In this position, you will be part of the team responsible for large scale computing systems, within which smaller subgroups are assigned responsibility for specific systems.

The operations team handles the following areas:

• Operations – The team consists of 2–6 people per group. Each group is responsible for one or several systems of a similar type.
• Software development – Mostly done in Python and Bash. The entire team oversees and participates in development work. Some system-specific components are also developed within the operations groups.
• Building new systems – A couple of times each year, NAISS deploys a new large computing or storage system that is then operated by one of the operations teams.
• User support and communication with users – This involves more than just problem solving. We also strive to make complex topics understandable and to anticipate and ideally resolve users’ next problem before it even arises.

At NAISS in Linköping, around 50 technically minded individuals work together, of whom just over 20 are involved in the technical operation of computing systems. We share the ambition of being among the best at developing and operating high performance computing and storage services with high availability, excellent usability, and first-class user support. Here, you will have the opportunity to deepen your technical expertise and learn from leading experts in the field. You will also be involved in shaping our future services within an organization characterized by short decision making paths.
