Assist in monitoring, maintaining, and troubleshooting Ubuntu 24.04 LTS servers to ensure reliability and performance for internal use
Perform routine system tasks such as patching/updates, user account management, backups, and log reviews
Help install, configure, and support common internal services (e.g., Nginx, Apache, PostgreSQL/MariaDB, file shares, basic DNS)
Support basic networking and security tasks (firewall rules with nftables/iptables, basic access controls, security patching)
Participate in container basics (Docker/Podman) under guidance, including running and monitoring containers
Contribute to simple automation scripts (Bash or Python) and configuration management (Ansible preferred) with supervision
Assist with monitoring tools (e.g., setting up alerts in Prometheus/Grafana or similar) and reporting
Document procedures, configurations, and issue resolutions to build team knowledge
Participate in on-call rotation (with senior support) and help resolve incidents
Learn and apply best practices for Ubuntu Server, virtualization, and internal infrastructure
Other support duties as assigned to keep internal systems running smoothly

Qualifications:

Basic to intermediate hands-on experience with Linux (Ubuntu/Debian preferred; can come from personal projects, homelab, internships, help desk, or entry-level IT roles)
Familiarity with Ubuntu Server fundamentals (command line, package management with apt, file permissions, processes/services via systemd)
Comfort with Linux scripting basics (Bash required; Python a plus)
Understanding of core services (web servers like Nginx/Apache, databases like PostgreSQL/MySQL, SSH, basic networking)
Willingness to learn configuration management (Ansible strongly preferred) and containers (Docker/Podman)
Basic knowledge of virtualization (e.g., VirtualBox, KVM, or cloud VMs) and networking concepts (TCP/IP, firewalls)
Strong problem-solving skills, attention to detail, and eagerness to learn new tools/technologies
Excellent communication and teamwork— you’ll collaborate daily with the team
US citizenship required
Capability to obtain US security clearance (if needed for certain projects)
Local candidates in/near Pittsburgh area only (hybrid flexibility possible after onboarding)

Preferred Skills (not required):

CompTIA Linux+, RHCSA, or similar certification (or working toward one)
Experience with monitoring/alerting tools (Prometheus, Grafana, Zabbix)
Exposure to Ansible, Git, or basic infrastructure-as-code concepts
Any prior help desk, IT support, or junior sysadmin experience
Homelab or personal projects running Ubuntu 24.04 (mention these in your application!)

Education:

Associate’s or Bachelor’s degree in Computer Science, IT, or related field (or equivalent self-taught experience/projects)
Recent graduates or those with relevant certifications encouraged to apply
