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. Mechanical Engineers at this level operate with full autonomy, own major portions of mechanical project design delivery, and mentor cross-functional teams.

Responsibilities

  • 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 submittents, 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.
  • 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.
  • Ability to review and interpret CFD reports to understand impacts to equipment performance and use to inform design decisions.
  • Ability 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.
  • 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.
