Ready to lead the job across both electrical and communications infrastructure?

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.

WHAT YOU'LL DO

• Run day-to-day electrical and telecommunications works on site across data centre and critical infrastructure projects.

• Coordinate electrical installation, control cabling and communications workstreams, including structured cabling and fibre infrastructure.

• Lead and support crews to deliver safe, tidy and high-quality work in live, secure and high-density environments.

• Work closely with Project Managers and Operations teams to keep works on programme and respond quickly to changing site priorities.

• Read and interpret drawings, specifications, scopes and work packs to plan activities properly and minimise rework.

• Coordinate trades, subcontractors, materials and site access so teams have what they need to complete work efficiently.

• Engage professionally with clients and site stakeholders, keeping communication clear and raising issues early.

• Drive strong HSEQ, quality, workmanship and documentation standards across the site team.

• Coach Technicians and Apprentices, set clear expectations and help build capability and accountability within the crew.

• Identify delivery risks, technical issues and productivity constraints early and work with the project team to resolve them.

WHO WE'RE HOPING TO MEET

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.

• Proven experience leading crews on data centre, commercial construction or other technically complex infrastructure projects.

• Strong practical understanding of electrical installation, control cabling and telecommunications infrastructure.

• Confidence coordinating multiple trades and work fronts in live or high-pressure project environments.

• Ability to read and interpret drawings, specifications and scopes and turn them into a clear site plan.

• Strong understanding of data cabling standards, quality expectations and best-practice installation.

• Safety-first leadership with a strong focus on compliance, workmanship and doing the job properly.

• Clear communication skills and confidence working with Project Managers, clients, subcontractors and site teams.

• A proactive, self-motivated approach with the ability to solve problems and keep teams productive.

LICENCES & EXPERIENCE THAT WILL HELP YOU STAND OUT

• A current NSW Electrical Licence is highly regarded.

• Current ACMA registration, ideally with Structured, Coaxial and Fibre Optic endorsements, is highly regarded.

• Candidates with both electrical and telecommunications licences/registrations and hands-on experience across both disciplines will be particularly well suited.

• Previous data centre, hyperscale, AI infrastructure or mission-critical project experience is highly regarded.

• Hands-on experience delivering control cabling such as ECMS, EMS and BMS in live project environments.





• Experience across structured cabling, fibre infrastructure and high-density communications environments.

• Construction White Card and relevant site tickets such as EWP or Working at Heights.

• Experience supervising Technicians, Apprentices, subcontractors and multi-trade site teams.

WHAT'S IN IT FOR YOU?

• Secure, permanent work on industry-leading data centre, AI, cloud and critical infrastructure projects.

• A genuine dual-discipline role across electrical and telecommunications delivery.

• Accrued RDOs and two pay reviews each year.

• Company-provided uniform and PPE.

• Salary packaging and novated leasing options.

• Ongoing training and career development through our Learn, Empower & Grow program.

• Opportunities to grow your leadership capability and progress across larger, more complex projects.

• Regular social events and access to discounted health and wellbeing benefits.

• Employee Assistance Program and wellbeing support.
