Senior Sustainable Design Engineer (Energy Modelling)

JDA WMS PTE. LTD.; Singapore; On-site; SGD 90,000 - 170,000; Full time

Job summary

JDA WMS Pte Ltd is seeking a Lead Energy Modeller to lead end-to-end energy modelling for design-stage and compliance-stage assessments across complex building typologies and large-scale projects in Singapore and the region. You will develop, review, and refine energy models to support sustainability objectives, decarbonization strategies, high-performance building design, and regulatory submissions.

Collaborate with project directors, sustainability consultants, and MEP/design teams to

Qualifications

• Bachelor’s or Master’s degree in Building Science, Mechanical Engineering, Architectural Engineering, Sustainable Design, Integrated Building Design, or related field.
• Proven experience in building energy modelling and sustainable building design, preferably within consulting environments delivering complex non-residential or mixed-use developments.
• Hands-on proficiency with energy modelling software such as IES VE, EnergyPlus, DesignBuilder, OpenStudio, or equivalent platforms.
• Strong skills in geometry and model development using Rhino, SketchUp, Revit, or similar software.
• Experience interpreting architectural, ACMV/MEP, and construction documentation to define simulation inputs and validate modelling assumptions.
• Working knowledge of Green Mark, LEED, PRM/code compliance processes, energy auditing, high-performance building design, zero-energy/zero-carbon studies, or comparable frameworks.
• Ability to conduct or supervise supporting analyses, including daylighting, glare, thermal comfort, passive design optimisation, and building envelope sensitivity studies.
• Excellent communication, interpersonal, and stakeholder management skills, with the ability to clearly present technical findings to both internal teams and clients.
• Self-motivated, detail-oriented, and capable of managing multiple projects effectively within tight deadlines.

Responsibilities

• Lead end-to-end whole-building energy modelling for both design-stage and compliance-stage assessments across complex building typologies and large-scale projects.
• Develop, review, and refine energy models to support sustainability objectives, decarbonization strategies, high-performance building design, and regulatory/certification submissions.
• Conduct parametric, sensitivity, and scenario-based analyses to guide passive and active design decisions throughout concept, schematic, and detailed design phases.
• Perform or oversee complementary building performance simulations, including thermal comfort, daylight, glare, passive design, and related studies where required.
• Review and interpret architectural, façade, MEP/ACMV, and controls documentation to ensure project-specific and technically robust modelling assumptions.
• Collaborate closely with project directors, sustainability consultants, and MEP/design teams to translate simulation results into practical design recommendations.
• Establish and maintain modelling QA/QC procedures to improve consistency, enhance delivery efficiency, and mitigate project risks.
• Serve as the primary technical expert and client-facing specialist for energy modelling projects in Singapore and across the region.
• Provide mentorship to junior analysts and modellers while strengthening technical expertise across SRO, Atelier Ten, and related teams.
• Coordinate with offshore/GDC teams as needed and act as the technical liaison between local and remote project delivery teams.
