- Manage projects and commissioning staff in current and upcoming data centre developments, including all commissioning-related contractual and financial aspects in consultation with STACK management.
- Direct the development and review of detailed test scripts for mechanical and electrical systems, ensuring compliance with mechanical engineering standards and operational benchmarks.
- Ensure all systems are commissioned in accordance with relevant mechanical engineering codes, Australian Standards, and international best practices.
- Review and approve commissioning documentation, including Cx Levels 4 and 5 test scripts, equipment functional performance tests, and vendor submittals.
- Attend customer factory witness tests (FWT) and factory acceptance tests (FAT) to verify equipment functionality against mechanical specifications.
- Oversee vendor coordination and equipment installation with a focus on mechanical system integration and performance.
- Perform inspections and lead QA/QC efforts to ensure all installed mechanical systems conform to approved design documentation.
- Supervise mechanical and process plant assembly, erection, testing, and commissioning to ensure adherence to mechanical engineering principles.
- Liaise with the Operations team to ensure mechanical systems are correctly handed over, operational, and compliant with maintenance standards.
- Review and interpret mechanical design documentation, including P&IDs, mechanical layouts, and single-line diagrams.
- Manage commissioning reporting, documentation, and record-keeping consistent with mechanical engineering requirements.
- Identify and investigate mechanical performance issues or failures during commissioning; implement corrective actions in coordination with design and construction teams.
- Support the development and continuous improvement of mechanical system specifications and standard commissioning practices across the business.
- Ensure safe work practices are adhered to in line with mechanical safety and design risk assessments.
- Act as the key point of contact for clients regarding mechanical system performance and compliance throughout the commissioning lifecycle.
- Provide mentoring and guidance to internal staff and consultants on mechanical systems and commissioning best practices.
- Support design documentation reviews including mechanical specification validation, operational sequence reviews, and equipment compatibility analysis.
- Contribute to sustainability and energy efficiency efforts by integrating LEED/Greenstar mechanical compliance criteria into commissioning and system performance benchmarks.
- Provide support to other regional data centre projects as needed.

**Requirements**:

- Bachelor’s degree in **Mechanical Engineering** or a closely related field.
- 3+ years of experience in mechanical system design, commissioning, or facility engineering within regulated or mission-critical industries (e.g., data centres, hospitals, energy facilities).
- Demonstrated understanding of thermodynamics, fluid dynamics, and mechanical system performance criteria.
- Experience with MEP design interpretation, commissioning planning, and mechanical systems integration.
- Strong knowledge of Australian mechanical engineering standards and regulatory frameworks.
- Proficiency in the use of Automated Commissioning Management Systems (ACxMS) and standard engineering software tools (AutoCAD, Bluebeam, MS Project, Excel).
- Ability to lead technical discussions with stakeholders, contractors, and design teams.
- Excellent written and verbal communication skills in English.
- Ability to travel as required (0-25%).
