Lead Mechanical Engineer (MCF/Data Centres)

Our Mission Critical Facilities (MCF) team is internationally recognised for delivering high-performance, resilient and sustainable data centre solutions for hyperscale, colocation and enterprise clients. As Southeast Asia continues to experience rapid digital infrastructure growth, we are strengthening our regional MCF leadership capability and are seeking an experienced Lead Electrical Engineer to drive technical excellence and delivery performance across major developments in APAC. We welcome both international and local candidates. The successful candidate will be based in either Ho Chi Minh City or Jakarta. Given the regional scope of the position, periodic travel between these locations will be required.

The Lead Mechanical Engineer will guide the design and delivery of resilient, high‑performance mechanical systems for mission‑critical data centres across Southeast Asia. As the mechanical technical authority, you will lead all design stages—from concept through detailed engineering and construction support—ensuring robust cooling and thermal management solutions that meet Tier and global MCF standards. You will work closely with the MEP Design Manager, Project Manager, and multidisciplinary teams, while mentoring regional engineers and upholding strong technical governance. Serve as the mechanical technical authority for data centre projects, ensuring resilience, compliance, and technical excellence. Lead the design and coordination of critical cooling systems: chilled water plants, cooling towers/dry coolers, CRAH/CRAC units, pumps, and heat‑rejection systems. Develop and review cooling plant capacity calculations, load assessments, diversity strategies, and energy‑efficiency approaches (PUE/WUE). Oversee thermal modelling and coordinate CFD analysis. Collaborate with the MEP Design Manager, Project Manager, and Controls teams to ensure integrated mechanical‑controls functionality. Lead mechanical design reviews to ensure quality, constructability, maintainability, and compliance with local codes and global mission‑critical standards (Uptime Institute, TIA‑942, ASHRAE). Establish mechanical standards, best practices, and QA/QC processes for the MCF team. Prepare and review technical specifications, reports, and employer’s requirements. Review contractor submissions, shop drawings, and proposals; support procurement and tender evaluations. Represent the company in client meetings, workshops, FATs, and site testing & commissioning. Mentor and develop mechanical engineers, supporting capability building across the APAC MCF team. Contribute to business development through technical input, presentations, and strategic initiatives. Maintain strong collaboration with global teams (NL, GER & UK). Manage and deliver mechanical work packages across multiple projects.

Technical Competencies Bachelor’s or Master’s in Mechanical Engineering or related field. 10+ years of multidisciplinary design and project delivery experience. Proven experience in mission‑critical facilities, ideally hyperscale or colocation data centres. Expertise in chilled water plant design (chillers, cooling towers/dry coolers, pumps, expansion systems, distribution networks). Strong knowledge of CRAH/CRAC systems, in‑row cooling, airflow management, and white‑space thermal performance. Demonstrated understanding of redundancy strategies (N+1, 2N, 2N+1). Solid knowledge of ASHRAE guidelines, Uptime Institute and TIA‑942 standards. Familiarity with energy‑efficiency optimisation (PUE, WUE). Experience coordinating thermal modelling and CFD analysis. Ability to develop mechanical control philosophies in collaboration with Controls Engineers. Experience preparing technical specifications, employer’s requirements, and tender documentation. Proficiency with relevant design tools (e.g., IES, Revit or equivalent). Strong understanding of international standards for mechanical systems in mission‑critical environments. Experience reviewing contractor submissions and supporting procurement, FAT, SAT, and commissioning. Experience working with international clients and multidisciplinary teams. Fluent in English, with strong communication skills. Uptime Institute ATD/ATS certification (or similar) is an advantage. Personal Attributes Strong technical authority with sound engineering judgement. Strategic, solutions‑oriented mindset. Commercially aware and able to balance project constraints. Confident communicator who can influence senior stakeholders. Collaborative leader with mentoring ability. Calm, decisive, and effective under pressure.
