Mechanical Field Engineer IIIPlay an integral role in delivering complex industrial construction projects by providing field engineering expertise that connects engineering design with safe, practical, and high-quality construction execution. As a Mechanical Field Engineer III, you will work directly at the project site to interpret design requirements, evaluate field conditions, resolve technical challenges, and verify that mechanical installations conform to approved engineering specifications.
Working closely with construction, engineering, quality, procurement, commissioning, contractors, and customer stakeholders, you will provide the technical support needed to keep work progressing safely and efficiently. Your expertise and engineering judgment will directly influence constructability, installation quality, schedule performance, system completion, and successful project delivery.
Purpose of the roleThe Mechanical Field Engineer III is responsible for providing advanced mechanical field engineering support throughout the construction phase of industrial projects. This role serves as a key technical interface between engineering design and field execution, ensuring construction teams have timely, technically sound solutions that maintain design integrity and support project objectives.
You will interpret engineering documentation, evaluate site conditions, coordinate field changes, resolve construction-related technical issues, and verify completed work against design requirements. Through strong technical judgment and multidisciplinary collaboration, you will help ensure mechanical systems and equipment are safely installed, completed, and prepared for turnover and commissioning.
You will be responsible for:- Providing mechanical field engineering expertise to support safe, efficient, and high-quality construction execution.
- Interpreting engineering drawings, specifications, calculations, equipment data, vendor documentation, and project requirements for construction teams.
- Evaluating actual field conditions and developing or recommending practical engineering solutions when site conditions differ from design assumptions.
- Supporting installation of rotating equipment, static equipment, packaged systems, vessels, pumps, compressors, heat exchangers, and other mechanical equipment within the assigned project scope.
- Reviewing and responding to Requests for Information (RFIs), technical queries, field changes, drawing discrepancies, and other construction-related engineering issues.
- Coordinating technical resolutions with home-office engineering, construction management, quality, procurement, vendor representatives, and commissioning teams.
- Verifying mechanical construction activities conform to approved drawings, specifications, applicable codes and standards, vendor requirements, and project procedures.
- Supporting constructability reviews, construction readiness assessments, workface planning, and field execution planning.
- Performing field inspections and technical walkdowns to verify installation quality, completion status, and compliance with engineering requirements.
- Identifying technical, constructability, quality, or interface issues that could affect safety, cost, schedule, or system completion and recommending appropriate solutions.
- Reviewing vendor information and coordinating technical issues associated with equipment installation, preservation, alignment, testing, and turnover.
- Supporting dimensional verification, equipment setting, alignment, grouting, mechanical completion, and associated inspection activities.
- Coordinating mechanical interfaces with piping, civil/structural, electrical, instrumentation, controls, quality, and commissioning disciplines.
- Supporting punch-list development, deficiency resolution, mechanical completion, system turnover, pre-commissioning, and commissioning readiness activities.
- Maintaining accurate field engineering records, redlines, technical correspondence, inspection documentation, and engineering change information.
- Preparing technical reports, field engineering assessments, recommendations, and project status information.
- Providing technical guidance to project personnel and assisting others with mechanical field engineering systems, processes, and tools.
- Supporting continuous improvement initiatives that enhance constructability, engineering quality, field productivity, and project execution.
