Critical Environment Technician

Role overview

CDC Data Centres is expanding its Melbourne team with a new data centre and is seeking a Critical Environment Technician to support live mission-critical operations in Laverton, Western Australia. This is a site-based position in a 24/7 shift pattern of 2 days, 2 nights, then 4 days off. The business is looking for someone with a background in critical infrastructure, electrical, HVAC, or similar trades, and will provide tailored learning through CDC Academy along with hands-on support.

About the company

CDC Data Centres is a sovereign, secure, world-class data centre operator with headquarters in Canberra and facilities across ACT, NSW, VIC, and New Zealand. Its connected campuses support co-location, containerised, and hyperscale computing environments through high-speed, carrier-grade networks. The organisation places strong emphasis on inclusion, diversity, and developing a committed, careful, and high-performing team.

What the role involves

As a Critical Environment Technician, you will help keep essential infrastructure running safely and reliably inside a live data centre environment. The role focuses on planned work, maintenance, and site reliability during business hours while working closely with the shift team. The work is grounded in procedures, safety, and understanding the impact of every action on power, cooling, fire systems, and monitoring systems that run continuously.

Key duties

• Track alarms and alerts related to electrical power, cooling, and fire protection systems, and respond appropriately.
• Carry out physical checks to confirm equipment and infrastructure remain within expected operating limits.
• Handle faults and incidents by assessing priorities and deciding when to escalate or involve contractors.
• Perform operational switching and control tasks to reduce the risk of unplanned outages.
• Assist with scheduled maintenance and supervise contractors on site to ensure approved methods and safety procedures are followed.
• Record incidents, maintenance work, and site observations to support continuous improvement.

Training and support

The company offers a tailored onboarding and training pathway through CDC Academy for people starting in this role. Learning is practical and hands-on, with opportunities to shadow and work alongside experienced Service Technicians to build capability over time.

Benefits and workplace support

• CDC Academy training to strengthen technical and professional development.
• CDC Day, which adds one paid leave day for health and wellbeing.
• Parental leave above minimum legal entitlements, supporting family life.
• Two days of volunteer leave for a cause or charity of your choice.
• Employee Assistance Program for employees and their families.
• Social events for staff and families, including BBQs, picnics, and community activities.

What the employer is looking for

The ideal candidate has worked in environments where reliability, process, and safety are essential, such as electrical, HVAC, mechanical, or broader critical infrastructure settings. This role may suit a qualified electrician or HVAC technician seeking a move away from a traditional hands-on trade position into operations, as well as someone earlier in their technical career who wants to learn how large-scale mission-critical facilities work. Strong motivation, attention to detail, and a willingness to learn are highly valued.

Desired background

• A trade or technical background in electrical, refrigeration/HVAC, mechanical, or a related discipline.
• Experience in critical or high-availability settings with strong compliance and safety expectations.
• Exposure to monitoring or control systems such as BMS, EMS, or SCADA.
• Familiarity with complex plant and infrastructure, including HVAC systems, power systems, generators, and fire systems.
• Strong troubleshooting, problem-solving, and situational awareness.
• Ability to prepare clear logs, reports, and documentation after incidents or maintenance work.

Essential requirement

Applicants must be Australian citizens and able to obtain and maintain an NV1 security clearance.
