Alliance SI is looking for an experienced, hands-on Supervisor to lead electrical and telecommunications works across major data centre and critical infrastructure projects in Sydney and surrounding regions.
This is a dual-discipline leadership role for someone who understands live, high-density data centre environments and can coordinate crews, trades and work fronts across electrical systems, control cabling and communications infrastructure.
You'll work closely with Project Managers and Operations teams, leading from the front to keep delivery safe, organised, productive and to the high standard our customers expect.
You'll already have solid supervisory or leading-hand experience across electrical, telecommunications, data centre or critical infrastructure projects. Strong practical capability across both electrical and communications delivery is important, and candidates who can confidently bridge the two disciplines will stand out.
