• Support, maintain, and optimize HPC systems, including cluster manager, operating system and network fabric installation, servicing, and advanced technical troubleshooting of hardware/software and parallel file systems (e.g., Lustre, GPFS).
• Monitor system performance, availability, and security using industry-standard tools and practices; ensure compliance with organizational policies and external regulations.
• Plan and execute upgrades, patches, enhancements, and migrations to ensure systems are current, secure, and optimized.
• Automate system administration tasks using scripting languages (Bash, Python, Perl, etc.) and configuration management tools (Ansible, Puppet, Chef, Terraform).
• Implement and maintain backup/recovery strategies, disaster recovery plans, and system documentation.
• Collaborate with development, network, and security teams to support application deployments and troubleshoot issues, particularly in multi-technology HPC environments.
• Provide technical consulting, mentoring, and guidance to junior team members and contribute to internal knowledge sharing.
• Ensure compliance with strict security protocols in sensitive environments (e.g., government, research); TSPV clearance will be required.
• Participate in on-call rotation and respond to system incidents and outages.
• Assist with technical proposals, solution design, and enterprise-level architecture for new projects and customer engagements.

About You:

• Bachelor's degree in Computer Science, Information Technology, or related field, or equivalent work experience.
• At least 5 years of hands-on experience managing Linux systems in production environments, including HPC systems.
• Expertise in Linux/Unix operating systems, parallel file systems (Lustre, GPFS), and networking technologies.
• Proficiency in scripting/programming languages (Bash, Python, Perl, C++).
• Experience with automation/configuration management tools (Ansible, Puppet, Chef, Terraform).
• Strong understanding of networking concepts (TCP/IP, DNS, DHCP, firewalls, VPNs).
• Familiarity with monitoring/logging tools (Nagios, Grafana, ELK Stack).
• Experience with containerization technologies (Docker, Kubernetes).
• Excellent problem-solving, analytical, and communication skills; able to diagnose complex technical problems to root cause.
• Demonstrated ability to work independently in multi-technology environments and collaborate across teams.
• Relevant certifications (RHCE, LFCS, AWS Certified SysOps Administrator, etc.) are a plus.
• TSPV Government Security clearance (mandatory).
