Linux System Engineer

Role Summary We are hiring a Linux Systems Engineer (L2/L3) to support the VDI platform layer in a distributed environment spanning ~20 hypervisors. The customer Linux team maintains the hypervisors (monitoring and vulnerability management). The Service Provider focuses on the VDI layer, including user issue resolution, Linux OS troubleshooting, patching/hardening support, automation/config management, scientific runtime enablement (limited scope), and container/VDI operational support. VDI core technologies include: SLURM + AWS DCV Docker + Kasm Workspaces Key Responsibilities A) Integrated Advanced Support (L2/L3) – Linux Systems (Core) Resolve incidents and service requests from researchers, faculty, and students. Perform OS troubleshooting including:  boot/kernel/service failures  package management and dependency failures  OS upgrades and migrations  Drive vulnerability management, OS patching, and OS hardening in alignment with security requirements.  Deliver performance tuning for CPU/memory/disk and GPU-related tuning as applicable. Support and maintain configuration management, including:  ongoing support and updates to Ansible and Puppet playbooks  Administer and manage OS-level agents for visibility and compliance, including tooling such as:  Nessus, Automox, Puppet, and related systems/agents  Contribute to Root Cause Analysis (RCA) using diagnostics and log analysis.  Support incident prevention via automation and lifecycle improvements. B) Scientific Environment (Limited Scope)  Configure environment modules (e.g., Lmod/Modules) and ensure correct runtime behavior.  Perform dependency resolution and enablement of application runtime environments.  Ensure users can load and run scientific toolchains reliably. C) VDI Platform Layer Support  Troubleshoot session access and performance issues.  Support scheduling and workload management interactions at the VDI layer.  Perform container platform operations at the VDI layer.  Handle multi-component troubleshooting for cases like:  VDI + scheduler + containers (within scope)  Coordinate with relevant teams when issues cross into hypervisor-level responsibilities. D) Engineering / Automation Functions  Provide automation-first operational practices using:  advanced scripting (bash, Python)  Ansible and Puppet (automation/config management)  Use IaC and CI/CD practices (including GitLab CI/CD) where applicable.  Maintain infrastructure lifecycle workflows using automation rather than manual steps. Mandatory Requirements (Must-Have) Linux administration expertise (mandatory):  Ubuntu LTS  Rocky Linux  NVIDIA GPU-enabled compute management experience (required).  Experience with scientific software (required; runtime/module enablement level).  Environment module management and dependency orchestration proficiency (required).  Experience with network-attached storage (NFS/SMB) configuration and support (required).  Ability to provide on-site / physical infrastructure support as per Section 3.2 (required).  Mandatory hands-on automation/IaC and configuration management experience including: o Ansible o Puppet o Automox o GitLab CI/CD  Demonstrated automation-first operations with bash/Python, systems integration, and infrastructure lifecycle management capabilities (required).  VDI context and troubleshooting exposure strongly preferred (aligned to SLURM + AWS DCV and Docker + Kasm Workspaces). Technologies (In Scope) VDI core: SLURM + AWS DCV, Docker + Kasm Workspaces Linux: Ubuntu LTS, Rocky Linux, system/service troubleshooting, OS patching/hardening, performance tuning Automation: Ansible, Puppet, IaC mindset, GitLab CI/CD, Automox Scientific runtime (limited): modules + dependency orchestration Storage: NFS/SMB Agents/Compliance: Nessus, Automox, Puppet/related tooling Candidate Profile You are a strong Linux engineer who can:  troubleshoot confidently at L2/L3,  patch and harden responsibly,  improve reliability via automation,  enable scientific environments without doing deep application debugging,  support VDI layer user issues and containerized workflows.
