About The Position

As a member of Antares’ IT organization, the IT Helpdesk Technician keeps technology used by software, engineering, manufacturing, lab, and business teams reliable, secure, and ready for work. The role provides hands-on support for workspaces, Windows, macOS, and Linux systems, mobile devices, identity and access systems, networks, conference rooms, and internal applications in an onsite, regulated environment.
