About the Assignment
We are looking for an experienced Linux System Administrator with a strong focus on automation, architecture, and platform engineering 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 such as simulation, visualization, and rendering. You will work with a Rocky Linux/RHEL-based stack and collaborate closely with HPC and infrastructure engineering teams to ensure a secure, scalable, and maintainable service.
Job Description
- Design, deploy, and maintain a Linux-based GPU-enabled Remote Desktop environment (Rocky Linux/RHEL, X11, Xfce4, NICE DCV, EF Portal/EnginFrame, SLURM).
- Build automation and Infrastructure-as-Code to enable consistent, repeatable deployments (primarily using Ansible).
- Drive improvements in security, scalability, performance, and long-term maintainability of the platform.
- Collaborate with HPC and infrastructure engineering teams to align platform capabilities with workload needs.
- Maintain clear documentation of architecture, configuration, deployment workflows, and operational procedures.
Requirements
- Solid experience as a Linux System Administrator, ideally on Rocky Linux or RHEL.
- Strong automation and Infrastructure-as-Code skills (Ansible or similar).
- Scripting proficiency, 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 tools (Prometheus-based observability preferred).
- Architectural mindset with the ability to design scalable and maintainable systems.
- Ability to work independently and take ownership of complex environments.
Nice to have
- 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) and monitoring/observability tooling.

Om Avaron AB
Avaron grundades med visionen om att skapa ett konsultbolag där kompetens och livskvalitet går hand i hand. Vi är ett nischat team som idag verkar inom komplexa miljöer såsom bank, finans och storskalig industri.
Som konsult hos oss får du det bästa av två världar: tryggheten och de spännande uppdragen hos stora, etablerade uppdragsgivare, kombinerat med det lilla bolagets snabbhet, transparens och personliga kontakt.
Vi tror inte på krångliga hierarkier eller onödig administration. Istället lägger vi kraften på det som faktiskt betyder något – att leverera värde i våra projekt och att se till att våra medarbetare trivs, utvecklas och har en balans i livet som fungerar på riktigt.
