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. What your day-to-day will look like: * Provide technical oversight for daily operation of critical mechanical, electrical, HVAC, and controls systems while maintaining awareness of system capacity, redundancy, and operational risk * Serve as the senior technical escalation point for abnormal system conditions and equipment failures, leading complex troubleshooting and providing direction during startups, shutdowns, load transfers, and emergency response * Lead and mentor operating engineers, plant technicians, electricians, and maintenance personnel by establishing work priorities, providing technical coaching, and reinforcing expectations for safety and operational discipline * Oversee preventive, predictive, and corrective maintenance programs by validating procedures, reviewing equipment performance and system trends, and ensuring maintenance activities are properly planned and risk-assessed * Champion safe work practices and ensure compliance with OSHA, NFPA, EPA, and local requirements including proper application of Lockout/Tagout, NFPA 70E electrical safety, confined space protocols, and hot work procedures * Review recurring equipment failures to support root-cause analysis, identify equipment requiring lifecycle replacement or capital investment, and drive continuous improvement initiatives * Ensure accurate documentation of maintenance activities within the CMMS and maintain appropriate SOPs, MOPs, EOPs, and engineering procedures that support operational readiness ## Related Videos - [What makes Cybersecurity different for critical infrastructure?](https://www.wearedevelopers.com/videos/571-what-makes-cybersecurity-different-for-critical-infrastructure) - [Designing Reliable Distributed Systems: Failures, Retries & Idempotency](https://www.wearedevelopers.com/videos/1963-designing-reliable-distributed-systems-failures-retries-idempotency) - [The Sustainability Race: AI's Promises, Pitfalls and Potential](https://www.wearedevelopers.com/videos/100155-the-sustainability-race-ai-s-promises-pitfalls-and-potential) - [Engineering/Manager Pendulum: Generating compound interest on your career](https://www.wearedevelopers.com/videos/100348-engineering-manager-pendulum-generating-compound-interest-on-your-career) - [From Space to Software: Reliability Lessons 40 Years After Challenger](https://www.wearedevelopers.com/videos/100283-from-space-to-software-reliability-lessons-40-years-after-challenger) - [Building the Nervous System of AI - Michael Kagan (NVIDIA)](https://www.wearedevelopers.com/videos/2133-building-the-nervous-system-of-ai-michael-kagan-nvidia) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [A Guide to Green Tech and Green IT Careers](https://www.wearedevelopers.com/magazine/374-a-guide-to-green-tech-and-green-it-careers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer)
