Lotus Works is seeking an experienced Mechanical Commissioning Lead to oversee and execute commissioning activities for mechanical systems within a mission-critical environment. The Mechanical Commissioning Lead will be responsible for developing commissioning plans, verifying installation and system performance, leading testing activities, managing deficiencies, and ensuring systems are ready for safe and reliable operation.

The ideal candidate will have 3+ years of mechanical commissioning experience, preferably within semiconductor facilities such as semiconductor manufacturing, data centers, pharmaceutical facilities, or other highly regulated environments. This individual should have strong knowledge of commissioning processes, mechanical systems, construction documentation, testing procedures, and industry standards.

• Develop and implement detailed mechanical commissioning plans aligned with ASHRAE, LEED, project specifications, and client-specific standards.
• Review construction documents, specifications, IFC drawings, sequences of operations, and design documentation to verify design intent and ensure adequate testing coverage.
• Lead and perform installation verification and field inspections of mechanical systems, ensuring equipment is installed correctly and complies with applicable codes, specifications, and design requirements.
• Lead Mechanical Operational Acceptance Testing (OAT) and Functional Acceptance Testing (FAT) to verify equipment and systems operate in accordance with approved sequences and project requirements.
• Complete and issue Green Tag certifications upon successful completion of applicable commissioning activities.
• Participate in Integrated Systems Testing (IST) to validate interaction between mechanical systems and other facility systems and confirm proper operation under integrated conditions.
• Support load testing, sequence validation, controls verification, and other performance testing activities as required.
• Identify, document, track, and resolve commissioning deficiencies and corrective actions throughout the project lifecycle.
• Maintain accurate commissioning records and project documentation using CxAlloy, Procore, and other project management or commissioning platforms.
