Job description

We are seeking a Senior Energy Analyst/Modeler to join the SJ’s Sustainability & Resilience Office, in Singapore. This is a specialist technical role focused on advanced building performance simulation, energy modelling, decarbonization strategy support, and quality assurance for high-performance building and infrastructure projects. The role is intended to strengthen local modelling capability, provide responsive support to project teams and clients, and bridge delivery between Singapore and the broader regional/GDC team.

Position purpose

Lead the development and execution of robust building energy models and related building performance simulations to support sustainable design, Green Mark / LEED / other certification pathways, decarbonization studies, and high-performance building outcomes.

Key Responsibilities

• Lead whole-building energy modelling for design-stage and compliance-stage studies across complex building types and major projects.
• Develop, review, and optimize energy models to support sustainability targets, decarbonization pathways, high-performance design, and authority/certification submissions.
• Carry out parametric, sensitivity, and scenario analysis to inform passive and active design decisions at concept, schematic, and detailed design stages.
• Support or lead complementary simulations where needed, including thermal comfort, daylight, glare, passive design, and related building performance studies.
• Interpret architectural, façade, MEP/ACMV, and controls documentation to ensure modelling assumptions are technically sound and project-specific.
• Work closely with project directors, sustainability consultants, and MEP/design teams to translate modelling outputs into actionable design recommendations.
• Establish and uphold modelling QA/QC standards, improve consistency and speed of delivery, and reduce project delivery risk.
• Act as a client-facing technical specialist for energy modelling matters in Singapore and the region. Mentor junior analysts/modelers and help build technical capability across the SRO & Atelier Ten and interfacing teams.
• Coordinate with offshore/GDC resources where relevant and serve as the technical interface between local and remote delivery teams.
• Bachelor’s or Master’s degree in Building Science, Mechanical Engineering, Architectural Engineering, Sustainable Design, Integrated Building Design, or a related discipline.
• Strong experience in building energy modelling and sustainable building design, ideally in consulting environments handling complex non-residential or mixed-use projects.
• Demonstrated experience with recognised modelling platforms such as IES VE, EnergyPlus, DesignBuilder, OpenStudio, or equivalent.
• Strong capability in geometry/model preparation using tools such as Rhino, SketchUp, Revit, or similar platforms.
• Experience in interpreting architectural, ACMV/MEP, and construction documentation for simulation inputs and calibration of design assumptions.
• Familiarity with Green Mark, LEED, PRM/code compliance workflows, energy audits, high-performance buildings, zero-energy / zero-carbon studies, or equivalent frameworks.
• Ability to perform or guide supporting studies such as daylighting, glare, thermal comfort, passive design optimization, and envelope-related sensitivity analysis.
• Strong interpersonal, communication, and stakeholder management skills, with the ability to explain technical findings clearly to internal teams and clients.
• Self-driven, quality-focused, and comfortable working under project deadlines across multiple concurrent assignments.

Singapore or regional project experience, especially with local submission workflows and authority expectations.
