About You

You have experience working in environments where reliability, safety, and procedure matter - whether that's through an electrical, HVAC, mechanical, or broader critical infrastructure background.

You might be a qualified electrician or HVAC technician looking to move away from a traditional tools‑based role and into operations, or someone earlier in their technical career who is curious about how large‑scale, mission‑critical environments operate.

Regardless of background, we value motivation, strong attention to detail, and a willingness to learn and develop within a growing industry.

• A trade or technical background in Electrical, Refrigeration/HVAC, Mechanical, or a related field (highly desirable)
• Experience working in critical or high-availability environments with strong safety and compliance requirements
• Exposure to monitoring or control systems such as BMS, EMS, or SCADA-type platforms
• Familiarity with complex infrastructure or plant equipment (e.g. HVAC systems, power systems, generators, fire systems)
• Strong fault-finding, problem-solving, and situational awareness skills
• The ability to produce clear documentation, logs, and post-incident reports
  

Australian Citizenship with ability to obtain and maintain a NV1 Security Clearance.

We are committed to fostering a diverse and inclusive workplace where all individuals are valued and respected. We believe that diversity of backgrounds, perspectives, and experiences leads to innovation and success. We actively promote equality and strive to create a welcoming environment for all employees. We are dedicated to building a team that reflects the diversity of our community and we encourage everyone to bring their authentic selves to work.
