Alliance SI is looking for a motivated Security Technician to join our team. Reporting to management and working as part of an experienced technical team, you'll support the cabling, installation and technical delivery of CCTV, Electronic Access Control Systems (EACS) and security networks.
This is a hands-on role for someone who takes pride in quality workmanship, enjoys solving technical problems and can communicate professionally with clients, builders, site supervisors and other trades.
You'll work across electronic security and communications infrastructure, with opportunities to strengthen your capability across access control, CCTV, cabling, fault-finding and high-security deployment environments.
You're likely already working as a Security Technician and have practical experience installing, configuring and maintaining electronic security systems. You'll be comfortable working independently and as part of a team, interpreting technical information and fault-finding when issues arise.
