Mechanical Field Engineer

LotusWorks is seeking an experienced Project Coordinator – Mechanical (Cx Engineer) to support Construction PMs on a large-scale semiconductor fab build in New Albany, Ohio, before transitioning into our Quality and Commissioning team as a Mechanical Commissioning Engineer.

This role is designed as a two-phase position, providing an opportunity to gain ownership of mechanical and process utility systems during construction before leading those same systems through quality, commissioning, and turnover activities. The successful candidate will balance schedule tracking, trade partner coordination, field quality oversight, and commissioning execution while maintaining a strong commitment to safety and clear, timely reporting.

Phase One: Construction Support (Project Coordinator)

During the construction phase, you will support Project Managers and field teams by coordinating mechanical scope, tracking project progress, and helping drive successful installation activities.

• Track mechanical scope against the project schedule, including look-aheads, constraints, and trade partner progress.
• Manage submittals, RFIs, and design change follow-up between Project Managers, design teams, and trade partners.
• Track inspection requests and issues through the project issues log to closure.
• Coordinate directly with trade foremen and field teams to resolve installation and construction issues.
• Conduct daily field walks to monitor installation status, safety compliance, housekeeping, and quality observations.
• Prepare weekly status reports, action-item logs, and progress updates for Project Managers.
• Support project planning and coordination activities to ensure mechanical systems remain on schedule and ready for quality and commissioning turnover.

Following construction activities, you will transition into the Quality and Commissioning team, taking ownership of systems you have supported through installation and leading them through testing, commissioning, and turnover.

• Execute QA/QC and commissioning inspections on semiconductor facility mechanical systems, including HVAC and make-up air systems, exhaust and abatement systems, PCW, UPW, hot and chilled water systems, CDA, process vacuum, and bulk gas systems.
• Witness pressure testing, flushing, and cleaning activities and verify compliance with P&IDs, project specifications, and ASME B31.3 requirements where applicable.
• Generate, track, and close punch-list items and support compilation of turnover documentation for Owner acceptance.
• Execute and document functional testing activities and support integrated system testing.
• Support system start-up, final turnover, and O&M readiness activities.
• Coordinate with contractors, vendors, and client stakeholders to ensure successful commissioning and handover of mechanical systems.

• Minimum 3 years of construction site experience, with previous experience supporting construction, commissioning, quality assurance, or quality control activities on mechanical systems.
• Working knowledge of mechanical and process utility systems such as HVAC and make-up air, exhaust and abatement, PCW, UPW, CDA, process vacuum, and bulk gas systems.
• Ability to read and interpret P&IDs, isometrics, and mechanical layouts.
• Familiarity with pressure testing, flushing, cleaning, and commissioning requirements, including ASME B31.3 standards.Experience managing submittals, RFIs, look-aheads, and issue logs through project close-out.
• Proficiency in Microsoft Excel and Smartsheet; experience with Procore, Autodesk Construction Cloud (BIM360), or commissioning software is an advantage.
• Strong organizational skills with the ability to manage multiple priorities and deliver clear written status reporting.
• Commitment to a strong safety culture and willingness to work in both construction and cleanroom environments.
• Semiconductor, pharmaceutical, data center, or other mission-critical facility experience is preferred.
• Experience with process piping systems, including orbital welded stainless steel, PVDF/PP piping, or UPW systems, is advantageous.

• Bachelor's Degree in Mechanical Engineering, Chemical Engineering, Building Services Engineering, or a related technical discipline preferred; equivalent construction, trade, or field experience will also be considered.
• Proof of education, licenses, and certifications required where applicable.
