James Tan

Electrical engineering professional contributing to the development and evolution of AirTrunk’s global reference data centre designs, with a focus on scalable, innovative, and customer-aligned electrical solutions for hyperscale environments. I support the establishment and continuous improvement of AirTrunk’s global electrical reference design, applying a strong understanding of hyperscale customer requirements, regional delivery needs, and emerging electrical technologies. My role involves conducting feasibility studies, technical reviews, and research into new electrical design concepts to support product development, customer solutions, and strategic roadmap decisions. As an electrical subject matter expert, I provide technical oversight across multiple regions, including Australia, Singapore, Malaysia, India, and Saudi Arabia. I work closely with internal teams, cross-functional disciplines, and direct-procured electrical equipment suppliers to ensure electrical systems are effectively integrated into reference designs and aligned with product, operational, commercial, and sustainability objectives. Key responsibilities and contributions include: • Developing and refining electrical concepts for hyperscale data centre customers. • Supporting the creation and governance of AirTrunk’s global electrical reference design. • Conducting feasibility analyses, studies, and reviews of new electrical technologies. • Managing and updating key technical documentation for electrical systems, ensuring alignment with evolving product requirements, other disciplines, and OSE specifications. • Communicating the electrical product roadmap, customer requirements, and research outcomes to business stakeholders. • Contributing to internal technical learning, knowledge sharing, and strategic initiatives across the electrical domain. • Providing flexible and adaptable technical support in response to changing project needs, priorities, and regional requirements.

+++Achievements • Ability to handle large workloads and work under pressure. Worked as the sole member of the product development team for a year before the team scaled up. Managed projects across 10 APAC sites spanning Sydney, Melbourne, Singapore, Johor Bahru, Hong Kong, Tokyo and Osaka during this period. • Prefab expert skilled at developing scalable solutions to meet regulatory and customer requirements. • Pioneered the development of AirTrunk’s first CDU for AirTrunk’s first Liquid Cooling campus. • Led a breakthrough in product development efforts to use Japanese equipment suppliers for Japan projects. This is a huge breakthrough as AirTrunk is an Australian company with procurement efforts led out of Australia. • Produced internal white papers on engineering topics to evaluate product technologies and optimize procurement strategies. • Conducted internal engineering podcasts to help drive innovation and spread knowledge. • Developed new IP for different BESS deployment strategies • Research and evaluate emerging technologies and equipment suppliers. • Research and develop new solutions to mitigate emerging policies and regulations. • Developed streamline work processes (internal and external) • Coordinate between customer design requirements and AirTrunk Technical Specification upgrades • Provide support for strategic customer accounts by developing bespoke products to meet their unique requirements. • Provide oversight and training for Design team to ensure design is scalable and of a consistent quality across all regions. +++Experience • 10 years of MEP technical experience – Contractor, Consulting engineer, Owner engineering representative • 8 years MEP systems design experience for data centers including AWS, Microsoft, Digital Realty, Equinix and AirTrunk. • Technical support for sales, engineering and procurement initiatives through participation in proposals and technical writing • Experience with AutoCAD and Revit
