● Drive Digital Strategy: Implement frameworks and policies to advance the "Smart Building" portfolio, ensuring all systems meet Client Digital Building standards.
● System Integration: Oversee the onboarding of buildings to the BOS platform, including ontology mapping, data validation, and the seamless integration of BMS and IoT devices.
● Performance Optimization: Analyze real-time operational data to identify inefficiencies, recommending solutions that enhance energy performance and reduce costs.
● Project & Vendor Management: Lead system enhancement projects and coordinate with OEMs/vendors for hardware upgrades, software integration, and defect resolution.
● Cybersecurity & Infrastructure: Manage building ICT networks and ensure strict cyber compliance for all connected devices and digital assets.
● Technical Support: Act as the primary escalation point for troubleshooting BOS integration issues, ensuring the resiliency and uptime of critical equipment.
● Asset Management: Regularly audit and manage the inventory of all digital hardware, software, and associated licensing.

Desired or preferred experience and technical skills:
● Education & Experience: Bachelor’s degree in Engineering or IT with a minimum of 8 years of experience, including at least 3 years in a specialized BOS, BMS, or Smart Building role.
● Smart Building Expertise: Deep understanding of IoT ecosystems, cloud integration, and BOS platform technology stacks (e.g., Clearblade, UDMI, Data Ontology).
● Building Systems Knowledge: Strong technical grasp of BMS, HVAC, Lighting (LMS), and Fire Alarm Systems, including how devices communicate to the cloud.
● Network Proficiency: Solid understanding of IT infrastructure and network protocols such as BACnet, Modbus, and KNX.
● Data & Analytics: Experience with data mapping, database management (SQL is a plus), and visualization tools like Power BI to drive data-driven decisions.
● Project Management: Proven ability to manage cross-functional projects, coordinate with OEMs/vendors, and oversee system handovers.
● Digital Proficiency: Advanced literacy in Google Workspace (Docs, Sheets, Slides) or MS Off ice, with the ability to create high-quality technical presentations.

Required Skills and Experience:
● Education & Professional Background: A Bachelor’s degree in Engineering, or Information Technology is preferred; however, we strongly encourage applicants with equivalent practical experience and relevant certifications to apply.
● Industry Experience: Minimum of 5 years of professional experience, with a specific focus on smart building technologies, BMS integration, or facility IT operations.
● Core Technical Expertise: Demonstrated proficiency in the BOS technology stack, including IoT device integration, cloud communication (e.g., Clearblade, UDMI), and data ontology mapping.
● Systems Knowledge: Strong working knowledge of Building Management Systems (BMS), HVAC, and Lighting Control Systems, including familiarity with standard protocols like BACnet, Modbus, and KNX.
● Data & Analytics: Ability to work with database concepts and visualization tools (e.g., Power BI, SQL) to interpret complex operational data.
● Project & Vendor Management: Proven experience managing technical projects, overseeing OEM vendors, and coordinating system deployments in a live facility environment.
● Cybersecurity Awareness: Solid understanding of cybersecurity principles as they apply to Operational Technology (OT) and IoT networks.
