Building Systems & Sustainability Engineer

Job Description 1. Role Overview The Building Systems & Sustainability Engineer plays a pivotal role in bridging ACMV engineering, Building Management Systems (BMS),and data-driven optimisation. This role is responsible for enhancing building performance through system integration, analytics, and continuous improvement initiatives. You will support the company’s transition from traditional engineering delivery to intelligent, sustainable, and digitally enabled building solutions, working across project teams, service operations, and R&D platforms (e.g. Zeggo ecosystem). 2. Key Responsibilities A. Building Systems Integration & Engineering Support integration of ACMV systems with BMS and smart control platforms Review HVAC schematics, control logic, and system sequences to ensure optimal operability Coordinate with project and service teams on installation, testing, and commissioning of BMS-related works Work with multi-disciplinary systems including ACMV, electrical, and fire systems where applicable B. Data Monitoring & Performance Analysis Monitor building performance through BMS, IoT devices, and digital platforms Validate data points, communication protocols (e.g. Modbus, BACnet), and system connectivity Analyse operational data (temperature, energy consumption, equipment runtime) to identify inefficiencies Develop dashboards and reports to track system performance and energy trends C. Energy Optimisation & Sustainability Initiatives Identify opportunities for energy savings and operational improvements Support implementation of optimisation strategies (e.g. scheduling, setpoint tuning, load balancing) Contribute to sustainability initiatives such as Green Mark, energy audits, and ESG reporting Assist in developing outcome-based solutions (e.g. energy performance improvement programs) D. Digitalisation & Platform Support Support deployment and validation of digital solutions (e.g. Zeggo platform, IoT gateways, analytics tools) Ensure accurate data flow from field devices to cloud or central monitoring systems Work with R&D and software teams to refine system logic, analytics models, and user interfaces Participate in pilot projects for smart building and hybrid cooling solutions E. Troubleshooting & Continuous Improvement Perform root cause analysis for system faults and performance gaps (e.g. 5-Why, trend analysis) Work with operations teams to resolve issues and improve system reliability Recommend system enhancements and retrofits to improve long-term performance Document learnings and contribute to internal knowledge base 3. Requirements A. Education & Experience Diploma/Degree in Mechanical Engineering, Electrical Engineering, Building Services, or related field 2–5 years of experience in ACMV, BMS, or building services engineering Experience with HVAC systems, controls, or facility management is preferred B. Technical Competencies Basic understanding of BMS systems and control strategies Familiarity with communication protocols (e.g. Modbus, BACnet) is an advantage Ability to read and interpret HVAC drawings and control schematics Exposure to data analysis tools, dashboards, or digital platforms is a plus C. Core Skills Analytical thinking and problem-solving capability Ability to translate technical data into actionable insights Strong coordination and communication skills across teams Willingness to learn and adapt in a digital and evolving environment 4. Preferred Attributes (High-Value Candidates) Experience in energy optimisation or energy audits Exposure to IoT platforms, Niagara Framework, or smart building systems Familiarity with ESG, sustainability frameworks, or Green Mark requirements Interest in digital transformation, automation, and AI-driven optimisation
