System Administrator—Customer Deployments

Conexus is a veteran-owned small business established in 1994. We develop and support asset management solutions using our proprietary software platform with RFID and RTLS technologies. Our customers include the Department of Defense (DoD) along with other government organizations and corporations.

Conexus is seeking a system administrator to deploy, maintain, and support secure, on-premises systems in customer environments. This is primarily a field-focused role, and the system administrator serves as the technical link between Conexus and customer IT teams, ensuring our solutions are successfully deployed and supported throughout their lifecycle. Between deployments, the system administrator supports Conexus's internal IT infrastructure and cybersecurity operations.

A successful system administrator is technically fluent, self-directed, and able to turn loosely defined requirements into practical solutions with minimal oversight. They are comfortable working independently across internal and customer environments and communicate effectively with technical teams, stakeholders, and end users.
