A Snapshot As Senior Mechanical Engineer, you will report to the Principal Mechanical Engineer and be based at our North Sydney headquarters. You will be a senior discipline specialist supporting AirTrunk's global project pipeline and the continuous improvement of our mechanical global standards, reference designs and Owner-Supplied Equipment (OSE). You will work across Design and Engineering, Design and Innovation, Development, Procurement, Construction, Commissioning and Operations. You will make an impact in the following ways:

Provide mechanical engineering input from concept through IFC to ensure designs comply with the AirTrunk Reference Design, Global Minimum Standards - Engineering (GMS-E), approved project requirements and applicable regulations.

Review designs and provide explicit, consistent and practical advice to consultants, AirTrunk Design Management and Site Engineering and Construction teams.





Work with design teams to identify and implement mechanical solutions that are safe, scalable, repeatable and adaptable across multiple regions.

Partner with Design and Innovation to provide a mechanical engineering lens on the development and continuous improvement of AirTrunk reference designs.

Be accountable for the continuous improvement and effective design implementation of assigned mechanical OSE products under the direction and approval of the Principal Mechanical Engineer.

Identify technical risks, non-compliances, interfaces and value opportunities early, recommending proportionate actions and escalating material decisions to the Principal Mechanical Engineer.

Convert lessons from design, delivery, commissioning and operations into practical improvements to global standards, reference designs, OSE products and assurance

Work across multiple regions and projects as required to drive global consistency in mechanical engineering and design solutions

Your Day to Day

Perform risk-based mechanical design reviews across concept, preliminary, schematic, detailed and IFC stages, documenting findings, actions, owners and required closure

Assess designs and technical submissions against the AirTrunk Reference Design, GMS-E, mechanical OSE specifications, approved project requirements, applicable codes and customer commitments.





Provide timely and consistent mechanical guidance to design consultants, Design Management, site engineering, project delivery and commissioning teams, explaining both the requirement and its technical intent.

Support Design Management in resolving technical issues while preserving its ownership of project design coordination and the project design Project delivery teams and their designers remain responsible for developing and coordinating the design.

Support design management in reviews of CFD studies against project requirements and global standards

Identify deviations, non-conformances, assumptions and unresolved risks; recommend technically sound resolution options and elevate departures, waivers or material decisions to the Principal Mechanical Engineer.

Develop scalable mechanical solutions that accommodate regional climate, water availability, regulations, supply-chain constraints and customer needs without unnecessary divergence from the global baseline.

Provide structured mechanical input to Design and Innovation on proposed reference design changes, supported by project evidence, technical analysis, performance data and lessons learned.

Drive assigned mechanical OSE improvement activities, including requirements capture, technical evaluation, product performance reviews, vendor feedback and proposed specification updates, for approval by the Principal Mechanical

Verify that approved mechanical OSE products and their interfaces are correctly incorporated into project designs, and support resolution of product integration

Provide subject matter expertise across cooling and thermal systems, ventilation, hydraulics, fuel systems, fire and life-safety
