• Troubleshoot mechanical, refrigeration, electrical and control system issues during commissioning.
• Monitor commissioning progress, identify technical issues and communicate updates to project stakeholders.
• Travel to project sites as required, including overnight or extended stays.

About You

• Mechanical Trade Qualification in refrigeration, HVAC or a related discipline.
• Refrigerant Handling Licence and relevant Electrical Licence.
• Proven experience commissioning or servicing precision cooling, HVAC or thermal management systems.
• Strong technical understanding of CRAC, CRAH, fan wall and liquid cooling technologies.
