Jeg's Automotive, LLC•Delaware, OH

About The Position

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.

Requirements

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.

Cisco experience
Microsoft and/or networking certifications (e.g., MCSA, CCNA, Security+)
