Job Description

Description:

The Mechanical Design Engineer III leads substantial portions of discipline design, coordinates complex systems, and independently delivers high-quality engineering work with limited supervision. This role is expected to anticipate issues, guide junior staff, communicate directly with project stakeholders, and contribute to reliable project execution from concept through construction.

• Perform HVAC load calculations, ventilation calculations, system sizing, psychrometric analysis, and equipment selections appropriate to the assigned level.
• Design and coordinate airside, hydronic, refrigeration, exhaust, ventilation, and associated HVAC systems based on project requirements.
• Develop equipment schedules, control sequences, diagrams, details, specifications, and other construction-document content that accurately communicates design intent.
• Coordinate mechanical systems with architectural, structural, electrical, plumbing, fire protection, controls, and equipment requirements.
• Evaluate energy-code requirements, equipment efficiencies, outside-air requirements, zoning, acoustics, maintainability, and constructability during design.
• Coordinate BAS/control requirements and sequences with controls vendors or design partners as required by project scope.
• Lead discipline design for small-to-midsize projects or major portions of larger projects with limited technical supervision.
• Coordinate directly with clients, architects, contractors, and other disciplines and drive closure of open technical issues.
• Prepare or substantially contribute to project narratives, specifications, estimates, studies, and construction-administration responses.
• Review work of junior engineers and designers for technical accuracy, coordination, completeness, and adherence to company standards.
• Assist project managers with scope, schedule, fee awareness, staffing needs, and identification of change conditions.
• Work with a high level of ownership, responsiveness, professionalism, and follow-through; communicate problems early and contribute constructively to team solutions.
• Support a positive, accountable team culture by helping others succeed, accepting feedback professionally, sharing knowledge, and maintaining high standards for quality and effort.
• Meet the role target utilization of 82% net over appropriate measurement periods while maintaining quality, client service, teamwork, and sound professional judgment.
• Some travel is required to document existing conditions, meet with clients and project teams, and perform site observations and punch-list activities.
• Must be comfortable using electronic devices such as iPads to document existing conditions, field observations, and client notes, and must be able, with or without reasonable accommodation, to safely climb ladders and access roofs, mezzanines, equipment rooms, and similar areas as required to perform job duties.

Requirements:

• Bachelor's degree in Mechanical Engineering, Architectural Engineering, or a closely related ABET-accredited engineering program.
• Typically 6-9 years of relevant mechanical building-systems design, consulting engineering, or closely related experience.
• EIT required or strongly preferred depending on discipline; PE licensure preferred or active progress toward licensure expected.
• Demonstrated ability to lead substantial portions of discipline design and review junior staff work.
• Working knowledge of the IMC, energy codes, ASHRAE standards, and common HVAC design practices.
• Autodesk Revit, Bluebeam, Microsoft 365, and applicable HVAC calculation software; familiarity with Carrier HAP, Trane TRACE 3D Plus, or similar tools is beneficial depending on role.
• Strong written and verbal communication, organization, attention to detail, and ability to manage multiple priorities in a remote professional environment.
• Ability to collaborate effectively with engineers, designers, project managers, architects, clients, contractors, and other project stakeholders.
