About The Position

As Chief Engineer for Critical Systems, you'll serve as the senior technical and operational leader ensuring the safe, reliable, and efficient operation of mission-critical building infrastructure. This role places you at the heart of maintaining systems where equipment reliability, environmental conditions, and continuity of operations are absolutely essential — from central chilled water and heating systems to electrical distribution, emergency generators, and building automation platforms. At JLL, we are collectively shaping a brighter way — for our clients, ourselves and our fellow employees — and you'll do exactly that by providing technical leadership and strategic direction that keeps operations running seamlessly. You'll oversee engineering personnel while serving as the escalation point for complex system issues, abnormal operating conditions, planned shutdowns, and infrastructure risks. What sets JLL apart is our culture of collaboration, locally and across the globe, which you'll experience firsthand as you work closely with Facilities Management, Engineering leadership, project teams, vendors, and client stakeholders to maintain operational continuity and drive consistent engineering standards across your assigned facilities.
