Position Overview

As a Mechanical Designer, you’ll work under the direction of a Mechanical Engineer and Project Manager to design HVAC and mechanical systems that meet high standards of performance, efficiency, and constructability.

This role blends technical design, fieldwork, and cross-discipline collaboration. As you grow, you’ll assume greater independence, lead coordination efforts, mentor junior staff, and handle larger project scopes.

Key Duties & Responsibilities

• Apply mechanical and thermodynamic principles to design and specify HVAC, plumbing, and mechanical systems.

• Perform HVAC load estimation, energy usage calculations, and energy code compliance documentation.

• Coordinate with architects, structural, electrical, and client teams to integrate all MEPT elements.

• Design systems including:

  • Ductwork layout, sizing, routing

  • Air distribution devices (grilles, diffusers, registers)

  • Central & terminal HVAC units (AHUs, FCUs, VAV boxes, etc.)

  • Hydronic piping (sizing, routing, pumps)

  • Central plant equipment (boilers, chillers, pumps, heat exchangers)

  • Control/automation systems (sequences, control strategies, integration)

• Perform field site surveys to document existing conditions, measurements, and constraints.

• Develop conceptual and construction cost estimates (materials, labor, installation).

• Model and detail in Revit/BIM—produce and maintain drawings, views, annotations, and schedules.

• Review vendor submittals, respond to RFIs, track changes, and support commissioning/as-built documentation.

• Visit construction sites to observe installations and flag deviations.

• Mentor junior designers or interns (for higher-level designers).

• Contribute to improving internal standards, templates, and workflows.

Required skills and experience

• Bachelor’s degree in Mechanical or HVAC Engineering (or related field) plus ~2 years of experience
  — OR —

• Associate degree/technical diploma with equivalent field experience.

• Solid understanding of thermodynamics, fluid flow, and heat transfer.

• Proficiency in Revit (non-negotiable).

• Familiarity with HVAC system types (VAV, DOAS, VRF, geothermal, etc.).

• Strong collaboration, communication, and problem-solving skills.

• Attention to detail and a willingness to grow into leadership of project scopes.

Compensation & Benefits

• Base Salary: $60,000 – $80,000 (dependent on experience & level).
