Mechanical Engineer - Mission Critical

About the role

The Mechanical Engineer is a technical expert and design leader responsible for shaping high-performance, integrated mechanical engineering solutions across major and complex projects. This role sets the standard for technical execution, QAQC rigor, and interdisciplinary coordination across the firm.

Essential Functions

• Lead the design and documentation of complex mechanical systems—such HVAC, plumbing and/or fire protection systems—with minimal oversight.
• Validate and approve key mechanical engineering calculations—such as refrigerant concentration limit calculations, plumbing system sizing, and equipment sizing—and integrate results into system design.
• Oversee setup of mechanical Revit models, including views, sheet organization, system browser strategies, and annotation standards.
• Resolve system conflicts during interdisciplinary coordination by collaborating with architectural, structural, and civil teams.
• Serve as the primary mechanical technical contact across internal and external project teams.
• Review and approve mechanical submittals, RFIs and substitutions; coordinate detailed responses with the broader team.
• Perform site visits, field verification, and punch walks with high autonomy; generate professional-level mechanical field reports.
• Provide mechanical design leadership from early concept through construction administration; inform system selection, performance targets, and documentation strategy.
• Guide QAQC reviews for mechanical deliverables and assist in the development of project-specific mechanical quality plans.
• Mentor junior engineers and mechanical designers through delegation, technical feedback, and one-on-one coaching.
• Participate in fee development, scoping, and resource planning for mechanical scope in project proposals.
• Lead internal and external project meetings by presenting mechanical system concepts, decisions, and trade-offs.

Mission Critical Specific Functions

• Have a strong understanding of mission critical HVAC systems, including but not limited to Fan Coil Walls, MDR/MMR CRAHs, air and water cooled chiller systems, and liquid cooling systems.
• Able to review and interpret CFD reports to understand impacts to equipment performance and use to inform design decisions.
• Able to estimate loads for equipment sizing and work with team members to oversee detailed load calculations.
• Knowledge of IEEC, ASHRAE 90.1 & 90.4 requirements for equipment/system efficiency requirements.
• Knowledge of typical redundancy requirements for data centers and impact on design requirements for specific tier.
• Knowledge of master planning for high level client interaction and support for site planning of future buildings and estimate utility impacts.

Requirements

• Bachelor's degree in Mechanical Engineering, or equivalent, required.
• P.E. licensure required.
• 10+ years in the AEC Industry preferred.
• An understanding of the financial status of projects as they progress, development of cost budgets for projects, value of client relationships and be able to deliver projects with a focus on the quality is required.
• Written and verbal communication skills commensurate with the position required.
• Strong organizational skills required.
• Revit experience required.
• Experience with computers, specifically for word processing, spreadsheet use/creation and email required.
• Detail-oriented, self-motivated, enthusiastic, flexible and curious personalities required.
• Ability to work well with others under deadline situations required.

Physical Requirements

• Prolonged periods of sitting at a desk and working on a computer.
• Must be able to effectively communicate in writing and verbally via phone, video conferencing, and in-person.
• Visual acuity to perform responsibilities.

Work Environment

• We embrace a hybrid model that promotes both autonomy and collaboration, including the freedom to work from home, with regular in-office days to connect with teammates and build culture.
• The office is a professional, open-space environment for collaborative and independent work.
