Senior Infrastructure Engineer

Avaron AB is a growing consultancy focused on technology, finance, and business support. We match your expertise with the market's most interesting assignments, offering a platform where your professional development is central.

We are looking for an experienced Linux System Administrator with a strong platform engineering mindset to design, build, and maintain a GPU-accelerated Remote Desktop (VDI) environment. The platform enables high-performance graphical remote sessions used for pre- and post-processing of HPC workloads, including simulation, visualization, and rendering. You will work with Rocky Linux/RHEL, X11 and Xfce4, and technologies such as NICE DCV, EF Portal (EnginFrame), and SLURM to deliver a stable, secure, and scalable solution.

• Design, deploy, and operate a Linux-based GPU-enabled Remote Desktop environment (Rocky Linux/RHEL, X11, Xfce4, NICE DCV, EnginFrame, SLURM).
• Build automation and Infrastructure-as-Code to enable consistent, repeatable deployments (primarily Ansible).
• Drive security, scalability, performance, and long-term maintainability of the platform.
• Collaborate closely with HPC and infrastructure engineering teams to align platform needs and improvements.
• Create and maintain documentation for architecture, configuration, deployment workflows, and operational routines.

• Solid experience as a Linux System Administrator, ideally with Rocky Linux or RHEL.
• Strong automation and Infrastructure-as-Code skills (Ansible or similar tools).
• Strong scripting skills, primarily Bash.
• Familiarity with CI/CD pipelines and version control (Git, GitLab).
• Understanding of X11, desktop environments (Xfce4, GNOME), and remote rendering/display protocols.
• Good knowledge of networking, security, and monitoring/observability tools (Prometheus-based preferred).
• Ability to design scalable and maintainable systems with an architectural perspective.
• Ability to work independently and take ownership of complex environments.

• Experience with HPC environments and SLURM workload manager.
• Experience with NICE DCV, EnginFrame (EF Portal), Open OnDemand, or similar remote visualization platforms.
• Familiarity with container technologies (Docker, Podman).
• Experience with monitoring/observability tooling.
• Python scripting experience.

Selections are made on an ongoing basis, so we recommend that you apply as soon as possible.
