Job Duties and Responsibilities:

• Candidate shall have extensive experience with development and implementation of mechanical and electrical system projects in customer facilities. Responsibilities include site investigations, analyzing energy use, finalizing savings calculations, finalizing cost estimates and written reports. In addition, the engineer manages engineering and design for implementation of design-build projects. Candidate has extensive familiarity with facility systems including chilled and hot water systems, air handling systems, building controls, and electrical distribution systems. The engineer works with other team members, and interfaces with customers, subconsultants, product vendors, subcontractors, and others to lead projects through development. Candidate

must have excellent written and verbal communication skills, analytical skills, and experience with building mechanical and electrical systems.

• In addition to the above, the Principal Mechanical Engineer is expected to provide senior-level technical leadership and oversight, acting as a subject matter expert in mechanical system design, optimization, and integration. Candidate must demonstrate deep expertise in advanced mechanical engineering principles, complex system modeling, and cross-disciplinary

engineering coordination. Experience leading multi-disciplinary engineering teams, conducting high-level technical reviews, establishing engineering standards, and mentoring junior staff is essential. Candidate must have a proven track record of guiding largescale or technically complex projects, advising stakeholders at all levels, and ensuring engineering excellence throughout project lifecycles. Strong strategic thinking abilities and the capacity to influence technical direction across programs and initiatives are required. Provide senior level technical oversight, review, and approval of mechanical engineering deliverables across multiple projects.

• Represent engineering leadership in customer meetings, cross functional coordination sessions, and executive level discussions.
• Coordinate mechanical engineering integration with electrical, controls, and construction teams to ensure cohesive system designs.
• Serve as the senior technical point of contact for high priority or complex customer engagements.
• Provide oversight and direction during project scoping, feasibility assessments, and early stage conceptual engineering.
• Support quality assurance processes, ensuring accuracy, completeness, and technical excellence in all mechanical engineering output.
• Support sales team as required with customer interactions.
• Lead and oversee the design engineering process for both new project development initiatives and projects progressing through full design and construction.
• Prepare and finalize reports and other documentation required for project work.
• Comply with safety requirements in the workplace and at customer sites.

Working Conditions:

• This position is remote.
• Travel required to customer facilities to conduct field surveys as needed.
• Must be able to work flexible hours to accommodate different time zones (Central/Eastern/Mountain/Pacific), if necessary.
