• Select appropriate mechanical and HVAC equipment and develop clear, accurate specifications.
• Ensure all designs and documentation comply with applicable building codes, HCAI requirements, industry standards and internal quality standards.
• Review engineering drawings, calculations and specifications to verify accuracy, completeness and adherence to project requirements.
• Oversee design quality, coordination and technical deliverables across project teams.
• Collaborate closely with multidisciplinary engineering teams across multiple offices to support integrated building design.
• Provide technical guidance, coaching and mentorship to junior designers and engineers.
• Contribute to continuous improvement initiatives, knowledge sharing and technical excellence within the mechanical discipline.
• Participate in coordination and review processes related to HCAI requirements and construction administration, as applicable.
• Communicate design concepts, technical decisions and project updates clearly to internal teams and project stakeholders.

• Advanced knowledge of HVAC and mechanical building systems design.
• Strong understanding of applicable building codes, industry standards and integrated building design principles.
• Advanced proficiency with Revit for mechanical and HVAC system modeling and documentation.
• Proficiency with AutoCAD for mechanical design and drafting.
• Proficiency with Bluebeam for drawing review, markups and coordination.
• Experience overseeing design quality, coordination and technical deliverables on complex projects.
• Working knowledge of HCAI requirements, codes, review processes and construction administration (strongly preferred).
• Familiarity with sustainable, resilient and high-performance building design principles.
• Strong communication and presentation skills, with the ability to convey technical information clearly to diverse audiences.
• Mechanical engineering experience with demonstrated experience in design and analysis of building systems.

• Experience working on healthcare facilities, hospitals, medical centers or other HCAI-regulated projects.
• Experience collaborating with multidisciplinary engineering and design teams across multiple locations.
• Experience providing technical guidance and mentorship to junior designers and engineers.
• Interest in contributing to continuous improvement, knowledge sharing and development of best practices within the mechanical discipline.
• Exposure to sustainable and high-performance building design strategies and their application in real projects.
• Interest in working within an employee‑owned benefit corporation structure with opportunities to share in company success.

The role offers remote and hybrid work flexibility, allowing a mix of work-from-home and office-based collaboration depending on project and team needs. The engineer works closely with multidisciplinary teams using digital design and coordination tools such as Revit, AutoCAD and Bluebeam in a highly technical, project-driven environment. The organization emphasizes complex healthcare and critical facility projects, providing exposure to challenging, regulated environments and integrated building design practices.

As an employee‑owned benefit corporation, the company fosters a culture of shared ownership, collaboration and long‑term engagement, supported by an Employee Stock Ownership Program (ESOP).
