About The Position
This is a new role due to company growth, requiring a well-rounded and technically deep Systems Administrator/Engineer with a minimum of 5 years of hands-on experience. The ideal candidate will be comfortable interacting with vendors, possess strong problem-solving skills, and have a service-oriented and collaborative approach. The role involves 5 days on-site work per week and on-call responsibilities for network issues. This position is not an entry-level helpdesk role and does not lead to management. A strong background in enterprise computer networking with secondary systems administration experience is essential. The company is a security-first organization with a predominantly on-prem technical environment, preferring to keep data on-prem and utilizing cloud services primarily for 3rd-party SaaS. The tech stack includes standardized Windows Server, deep Active Directory knowledge, on-prem Microsoft Exchange, networking (routing & switching), and SQL/DBMS experience. Some Linux/Unix exposure is a plus. Current initiatives include transitioning from Cisco routers to Check Point firewalls with SD-WAN, and ongoing infrastructure upgrades. The company seeks someone from a mature but not siloed work environment.
