The Mechanical Engineer supports the delivery of facility engineering projects and the maintenance and operation of critical facility systems. The role spans the full asset lifecycle, from design review, construction, and commissioning, through handover/takeover (HOTO) and operational readiness, to the safe, reliable, and efficient steady-state operation of cleanroom, laboratory, manufacturing, office, and related facility infrastructure. Working closely with Client assigned Project Teams, JLL Project and Development Services (PDS), JLL Integrated Facility Management (IFM), client stakeholders, and contractors, the Engineer helps ensure that systems are designed and built to be operable and maintainable, and are then run to the highest standards of safety, reliability, and efficiency.
Key Responsibilities:
Project Delivery
Support the planning of project scope, schedule, budget, and resources, and help deliver facility projects (including expansions, upgrades, fit-outs, and MEP works) safely, on time, and within the approved budget to support the client's business needs.
Act as the engineering technical and operations interface within the project and multidisciplinary team, from design development through to handover.
Review design documents at each stage for operability, maintainability, redundancy, access, and lifecycle cost, and track design-for-operations comments to close-out.
Review and develop technical specifications, drawings, shop drawings, method statements, equipment selections, and contractor submittals, and prepare project specifications, operating procedures, and work instructions as required.
Provide technical expertise across the facility systems relevant to the role's engineering discipline, which may include HVAC and cleanroom air systems, process cooling and utilities, compressed air and gas systems, electrical power distribution and UPS, water and wastewater, chemical distribution, fire protection, and building management and control systems.
Coordinate the interface between base-build systems and process or production equipment, including utility matrices, points of connection, and equipment hook-up requirements.
Liaise between clients, consultants, contractors, OEMs, and internal teams to ensure project requirements are met, and develop effective vendor and OEM relationships.
Provide construction-phase technical support, including site inspections, quality walkdowns, RFI responses, and non-conformance tracking.
Assist with tracking project costs and capital approvals so that expenditure remains within the approved budget, and support procurement processes and vendor management.
Witness factory and site acceptance tests and participate in all levels of commissioning, including integrated systems testing and, where applicable, testing and balancing and cleanroom certification.
Identify and escalate technical and project risks, support timely resolution of project issues, and contribute to progress reporting for key stakeholders.
Ensure adherence to health and safety regulations on all projects.
Handover (HOTO) and Operational Readiness
Support operational readiness planning so that new or modified facilities and systems are ready to operate on day one.
Support the handover/takeover (HOTO) process, helping secure complete handover documentation, including as-built drawings, O&M manuals, warranties, test certificates, commissioning records, and OEM training, and track snag and punch-list closure from an operations perspective.
Help build the asset register and tagging, configure the computerized maintenance management system (CMMS), and develop planned preventive maintenance (PPM) schedules and job plans based on OEM and statutory requirements.
Draft and help validate site SOPs, MOPs, EOPs, and alarm response procedures before go-live.
Provide input to the critical spares strategy and maintenance vendor scopes, and support procurement of service contracts.
Review BMS/FMS and other monitoring system point lists and alarm priorities to ensure critical systems are monitored and escalated correctly.
Support the defects liability period, warranty claims, and contractor close-out, monitoring post-handover performance until the facility reaches stable steady-state operation, and capture lessons learned for future projects.
Maintenance and Operations
Support the safe, reliable, and efficient operation and maintenance of facility systems within scope, supporting building, cleanroom, laboratory, manufacturing, and office environments.
Plan, organize, and coordinate planned preventive and corrective maintenance, driving PPM compliance, backlog reduction, and equipment reliability.
Prepare MOPs, permits to work (PTWs), and lockout/tagout plans for review and approval, covering all maintenance activities in line with site procedures.
Apply JLL Risk Management and Change Management processes for all work affecting critical systems.
Respond rapidly to critical incidents and abnormal events, maintain incident reports, support root cause analysis and the implementation of corrective actions; participate in the on-call escalation roster.
Promote onsite team compliance with SOPs, MOPs, EOPs, JLL and client HSE requirements, and all applicable local and national legislation, codes, and standards for the country of operation.
Support statutory compliance for facility systems, including licenses, permits, inspections, and test certificates, and track renewals so they are completed on time.
Coordinate service vendors, including scope adherence, input to performance reviews, and service report quality.
Coordinate and deliver daily work and provide technical guidance, coaching, and on-the-job training to technicians and operators.
Conduct regular site and equipment inspections with technicians and operators.
Analyze equipment, maintenance, and operations data to identify trends, improve reliability, and reduce energy consumption.
Contribute to performance reporting against JLL KPIs and SLAs, and act as an engineering point of contact for client stakeholders on day-to-day matters.
Contribute to lifecycle replacement and capital improvement recommendations, and carry operational learning back into future project design and delivery.
Support holistic building operations, maintenance, and management capability with cross-functional teams to ensure strong IFM capability, operational resilience, and robust business continuity planning (BCP) and implementation.
Safely adapt to the speed and pace of change in line with client output demands and scaling.
Flex skills and deploy across multiple locations as required.
Requirements
