Mechanical Engineer

About the Role

Join a dynamic, multidisciplinary engineering team where you’ll lead the design and delivery of mechanical building systems across a diverse portfolio of projects, including commercial, life sciences, government, mission critical, and industrial facilities.

As an Engineer III, you’ll take meaningful ownership of projects from concept through construction, combining hands-on mechanical design with project leadership and multidisciplinary coordination. You’ll work alongside experienced engineers and designers to develop practical, high-quality solutions that meet project requirements, applicable codes and standards, and our clients’ operational goals.

This is an opportunity for an experienced mechanical engineer who enjoys solving complex design challenges, collaborating across disciplines, and seeing their work through from early design to successful execution.

• Work under the general administrative direction of the Mechanical Division Manager.
• Support multiple projects and priorities concurrently.
• Provide technical direction to engineers and designers in the preparation of drawings and engineering calculations.
• Apply strong Revit proficiency and hands-on design experience to independently execute engineering designs while working under the guidance and oversight of division leadership.
• Collaborate and coordinate with other engineering disciplines, project stakeholders, and design professionals.
• Research, interpret, and apply applicable building codes, industry standards, and project requirements.
• Prepare engineering analyses and reports, including existing-conditions assessments.
• Develop preliminary and detailed mechanical engineering designs.
• Prepare engineering calculations and review calculations completed by others.
• Develop engineering specifications and control sequences with support from Senior and Chief Engineers.
• Prepare COMcheck calculations.
• Perform design quality control, monitor project progress, and proactively communicate potential scope changes to management.
