A summer internship should show you how the work actually comes together. MTech's Project Engineer Internship is a 13-week rotation for students who want to understand the full lifecycle of commercial mechanical construction - from engineering and design through field operations, project management, commissioning, and closeout.

You will work alongside engineers, Project Engineers, Project Managers, Field Managers, skilled craft professionals, and other teams across MTech. Rather than observing from the sidelines, you will contribute to active projects, visit jobsites, build technical knowledge, and see how office decisions become installed HVAC and plumbing systems.

The program is designed primarily for students entering their junior or senior year in Mechanical Engineering, Architectural Engineering, Construction Management, or a related discipline. It also serves as an early pathway into MTech's full-time Project Engineer I Rotation Program following graduation.

• Support active project teams with submittals, current drawings, requests for information, change documentation, equipment tracking, and other project records.
• Assist Project Engineers, Project Managers, and Field Managers with material and equipment procurement, delivery coordination, and follow‑up with vendors, subcontractors, and purchasing.
• Learn how project scope, schedule, budget, documentation, communication, and client commitments work together throughout construction.

• Work with MTech's engineering team to understand the design-build process and how mechanical systems are developed for different building types.
• Assist with heating and cooling load calculations, equipment sizing and selection, and introductory HVAC or plumbing‑system design tasks appropriate to your experience.
• Review drawings and technical information to understand design intent, interdisciplinary coordination, constructability, and the connection between design and field installation.

• Spend time on active jobsites with field leadership to observe project planning, installation sequencing, safety expectations, quality standards, and day‑to‑day problem‑solving.
• Shadow pipe fitting, plumbing, and sheet metal teams to learn the purpose, installation methods, and coordination needs of each trade.
• Build relationships with the skilled professionals who install the systems and learn how thoughtful engineering and project decisions support successful field execution.

• Assist with start‑up, commissioning, punch‑list, and closeout activities as project schedules allow.
• Help coordinate operations and maintenance manuals, start‑up information, warranty documentation, as‑built drawings, and other turnover requirements.
• Follow selected project activities from early coordination through completion to understand what successful delivery looks like for MTech and its clients.
• Regular and predictable attendance is expected in order to meet the requirements of this position.
• Other duties as assigned.

• Current enrollment in a bachelor's degree program in Mechanical Engineering, Architectural Engineering, Construction Management, or a related field. Students entering their junior or senior year are preferred.
• Interest in commercial construction, building systems, mechanical design, field operations, or project management.
• A curious, proactive approach…
