Original job description

Job Title: Mechanical HVAC Engineer

Job Description

This role offers the opportunity to contribute to a major infrastructure expansion for a highly innovative aerospace-focused environment. As a Mechanical HVAC Engineer, you will play a key role in the design, construction, commissioning, and startup of large-scale HVAC and chilled water systems that support power distribution, substations, mission-critical facilities, and industrial operations. You will work in a hands-on capacity, solving complex technical problems, collaborating closely with construction teams, and seeing projects through from initial design to full activation. The position supports multiple facility projects running in parallel, with significant construction activity and ongoing efforts in system activation, startup, tuning, and optimization. You will join a deliberately small, high-visibility team where motivated engineers have meaningful ownership of systems and solutions.

Responsibilities

Support the design and implementation of industrial HVAC and chilled water systems for mission-critical facilities.
Assist with HVAC infrastructure that supports power substations and electrical distribution equipment.
Collaborate with third-party engineering consultants serving as owners representatives to align design and implementation with project goals.
Help develop technical requirements, specifications, and Requests for Proposal (RFPs) for mechanical construction contractors.
Participate in contractor selection processes, design reviews, and overall project execution activities.
Support commissioning efforts for HVAC, chilled water, and mechanical utility systems to ensure reliable and efficient operation.
Coordinate closely with design, construction, and operations teams throughout the full project lifecycle.
Analyze facility cooling loads and contribute to equipment sizing activities to meet operational and efficiency requirements.
Assist in startup, troubleshooting, tuning, balancing, and optimization of installed HVAC and chilled water systems.
Evaluate engineering solutions and recommend improvements to meet evolving operational, reliability, and efficiency targets.
Interface directly with internal stakeholders, contractors, and commissioning teams to maintain clear communication and alignment.
Apply knowledge of chilled water plant design, industrial HVAC systems, central utility plants, air handlers, and large air movement systems.
Support work related to variable-speed pumping systems, power distribution facility cooling, building mechanical infrastructure, and controls integration.
Contribute to energy and thermal management strategies for large-scale cooling systems, including multiple 100-ton chilled water systems and high-capacity power hub cooling approaching 180 tons.
Assist with systems that include chiller plants utilizing variable-speed pumping, large industrial air handling units, cooling infrastructure for 4160V and 480V electrical equipment, and VRF/VRV systems.

Essential Skills

Bachelors degree in Mechanical Engineering or a closely related engineering discipline.
25 years of engineering experience in HVAC, facilities, mechanical systems, or chilled water infrastructure.
Practical experience with HVAC system design, installation, construction support, or commissioning.
Solid understanding of chilled water systems, air handlers, pumps, and associated mechanical equipment.
Familiarity with ASHRAE standards and industry best practices for HVAC and mechanical systems.
Strong problem-solving abilities with a high level of engineering curiosity and initiative.
Ability to work effectively in a fast-paced construction and operational environment with multiple projects running in parallel.
Experience working with or around VRF and VRV systems in industrial or mission-critical settings.
Ability to collaborate with cross-functional teams including design, construction, operations, and external consultants.
Effective communication skills for interfacing with stakeholders, contractors, and commissioning teams.

Additional Skills & Qualifications

Experience in mission-critical facilities, industrial facilities, utility infrastructure, manufacturing plants, aerospace, semiconductor, data center, or power generation environments.
Hands-on VRF/VRV design experience for complex facilities and cooling applications.
Experience supporting commissioning, startup, balancing, and system optimization for HVAC and chilled water systems.
Familiarity with HVAC controls and building automation systems, including integration with central utility plants.
Experience reviewing contractor submittals, technical specifications, and construction drawings for mechanical systems.
Proficiency with AutoCAD and/or Revit for mechanical and HVAC design and documentation.
Active participation in ASHRAE or other professional engineering organizations, demonstrating ongoing professional development.
Exposure to chilled water plant design, central utility plants, large industrial air handling units, and power distribution facility cooling.
Understanding of energy and thermal management strategies in large-scale industrial or mission-critical environments.

Work Environment

The work environment centers on large-scale industrial and mission-critical facilities, including power distribution hubs, substations, and advanced aerospace-related operations. You will work closely with design, construction, and operations teams in a fast-paced setting that moves from conceptual design through heavy construction, commissioning, startup, and system optimization. The role involves frequent interaction with third-party engineering consultants, mechanical contractors, and commissioning specialists, and requires comfort with active construction sites and complex mechanical infrastructure. You will work with technologies such as chilled water plants with variable-speed pumping, industrial HVAC systems, central utility plants, large air handling units, high-capacity power hub cooling systems, cooling infrastructure for high-voltage electrical equipment, and VRF/VRV systems, often integrated with sophisticated controls and building automation platforms. The team structure is intentionally small, promoting high visibility, significant ownership of projects, and close collaboration. Standard professional attire is expected in office and meeting settings, with appropriate safety gear required when visiting construction or industrial areas.
