Facilities Mechanical Technician – JLL

What this job involves: Join JLL as a Facilities Mechanical Technician supporting a cutting-edge semiconductor Research and Development facility where precision meets innovation. In this critical role, you'll maintain the specialized mechanical systems that keep advanced R&D operations running at peak performance. You'll work with high-purity process systems, monitor critical infrastructure data, and ensure life-safety compliance in a dynamic cleanroom environment. This position offers the opportunity to apply your pipefitting and plumbing expertise in a high-tech setting while contributing to groundbreaking semiconductor research. If you're a versatile technician who thrives on variety, values technical accuracy, and wants to be part of a collaborative team supporting mission-critical operations, this role provides an exceptional opportunity to grow your career in the semiconductor industry.

What your day-to-day will look like:

• Execute diverse mechanical work orders including high-purity piping installations, process system repairs, soldering copper pipe, and maintaining standard building plumbing and drainage systems

• Monitor and log critical system usage data from water and gas meters into the Computerized Maintenance Management System (CMMS), analyzing trends to identify potential failures before they impact operations

• Maintain and inspect life-safety equipment including emergency eyewash stations and safety showers in accordance with ANSI/OSHA standards and facility protocols

• Perform preventive and corrective maintenance on Process Cooling Water (PCW), Deionized (DI) Water systems, and Industrial Waste Neutralization (IWN) systems to ensure continuous R&D operations

• Collaborate with engineers and cross-functional trades to support evolving tool hook-ups, facility improvements, and infrastructure upgrades

• Work in both standard facility areas and controlled cleanroom environments wearing specialized PPE ("bunny suits") while following strict contamination control protocols

• Provide on-call support for critical facility systems to maintain high-uptime operations and respond to urgent maintenance needs

Required Qualifications:

• 3–5+ years of hands-on experience in pipefitting, plumbing, or industrial mechanical maintenance

• Demonstrated proficiency in soldering, brazing, and joining various pipe materials including PVC, CPVC, stainless steel, and copper

• Experience working in semiconductor, high-tech manufacturing, or similar controlled-environment facilities

• Proficiency with Microsoft Office applications and digital work order management systems or CMMS platforms

• Strong technical competence with ability to interpret technical drawings, system schematics, and equipment specifications

Preferred Qualifications:

• Journey-level pipefitting or plumbing certification or equivalent demonstrated technical competency

• Working knowledge of specialized water treatment systems including Process Cooling Water (PCW) and Deionized (DI) Water systems

• Familiarity with Industrial Waste Neutralization (IWN) systems and pH balancing protocols

• Understanding of ANSI Z358.1 standards for emergency eyewash and shower equipment maintenance

• Experience working in cleanroom environments (Class 100/10/1) and comfort wearing specialized cleanroom PPE

• Advanced analytical skills with ability to perform root-cause analysis using system data logs and trend monitoring

• Team-oriented mindset with strong communication skills and willingness to support diverse facility needs
