IT Infrastructure Specialist

JEGS is looking for a hands-on, all-around IT generalist to serve as the backbone of our internal systems, network, and infrastructure. This role consolidates system administration, network engineering, and infrastructure support into a single specialist position - ideal for someone who wants broad ownership across servers, networking, security, and business-critical systems rather than a narrow slice of any one discipline. You will be the primary owner of our Windows Server environment, network infrastructure, endpoint support, backup/disaster recovery, and day-to-day security operations, while also providing secondary support on our IBMi (AS/400) environment and cloud-connected systems (Azure SQL, Snowflake). You’ll work closely with the Director of IT and cross-functional teams to keep our systems secure, available, and performing at the level our business demands. Systems Administration

• Install, configure, patch, and upgrade Windows Server operating systems, physical/virtual hosts, and core infrastructure services.
• Manage Active Directory, Group Policy, user accounts, permissions, and access controls to ensure secure and efficient operations.
• Administer Microsoft 365 / Exchange Online, Teams, and related productivity and collaboration platforms.
• Monitor system performance and capacity, and proactively troubleshoot server, storage, and virtualization issues.
• Implement and maintain backup and disaster recovery procedures across servers, NAS/SAN, and cloud storage targets.
• Maintain documentation of system configurations, procedures, and technical resolutions in support of internal policy and compliance.

Network Engineering

• Design, configure, and maintain LAN/WAN, wireless, VPN, firewall, and switching infrastructure across on-site and hybrid locations.
• Manage core network services including DNS, DHCP, and network access control.
• Support and help mature edge security tooling (e.g., Cloudflare WAF, rate limiting, bot mitigation) in coordination with the Director of IT.
• Monitor network health, throughput, and uptime; respond to and resolve outages and degraded performance.
• Maintain network diagrams and documentation, and support disaster recovery and failover planning.

Security & Compliance

• Implement and audit security controls across endpoints, servers, and network infrastructure, including antivirus/anti-malware, spam filtering, and patch management.
• Perform routine security reviews, respond to incidents, and support remediation efforts.
• Ensure data integrity through regular backup verification and tested recovery procedures.
• Support access governance - onboarding, offboarding, and periodic access reviews across systems.

Enterprise Systems & Data Support (IBM i / Cloud)

• Provide day-to-day operational support for our IBM i (AS/400) environment, including job monitoring, backups, and basic troubleshooting alongside outside hardware/licensing partners.
• Support connectivity and data integration between IBM i, ERP, ecommerce, and warehouse systems (file feeds in CSV, XML, JSON).
• Provide basic DBA support and troubleshooting for Azure SQL and/or Snowflake environments - monitoring availability, performance, and access.
• Partner with the applications team on integration and automation needs (e.g., Power Automate, PowerApps) where infrastructure or connectivity is involved.

End-User & Desktop Support

• Provide tiered technical support to associates, resolving hardware, software, and connectivity issues with minimal downtime.
• Support desktop/laptop hardware, peripherals, and both Windows and Mac environments.
• Train and onboard new personnel on desktop applications and IT procedures.
• Participate in an on-call rotation to maintain system uptime and business continuity outside business hours.

• 5+ years of experience in system administration, network engineering, or a comparable hands-on infrastructure role.
• Strong knowledge of Windows Server environments - installation, configuration, Active Directory, and Group Policy.
• Solid networking fundamentals: TCP/IP, DNS, DHCP, VPN, firewalls, and switching; Cisco experience a plus.
• Experience with backup and disaster recovery tooling and practices (e.g., Backup Exec, NAS/SAN, cloud backup).
• Exposure to IBM i / AS/400 environments is a strong plus, but not required - willingness to learn a homebrewed ERP environment is essential.
• Working familiarity with SQL and relational databases (Azure SQL, Snowflake, or similar) is a plus.
• Excellent troubleshooting skills and comfort working under deadlines in a fast-paced, business-critical environment.
• Strong interpersonal and communication skills, with comfort interacting with personnel at all levels of the organization.
• Good organizational and time management skills; detail-oriented and self-directed.
• Experience writing and maintaining technical documentation and procedures.
• Microsoft and/or networking certifications (e.g., MCSA, CCNA, Security+) are a plus but not required.
