Estimate design budgets and man-hours, partnering with PM/PE for project scope, phasing, and scheduling.
Provide technical leadership, guiding and mentoring junior designers (I, II, III) to maintain project quality and timelines.
Interface directly with clients to educate them on design requirements and project expectations.
Review and approve engineering drawings for accuracy, completeness, and code compliance.
Conduct QA/QC reviews, collaborating with technical managers as needed.
Manage fast-paced deadlines without compromising design quality or project integrity.

Active PE license (required).
8 years of mechanical engineering experience in building systems design.
Demonstrated expertise in discipline-specific codes, building codes, and industry standards.
Proficiency in REVIT, mechanical engineering modeling tools, and Microsoft Office Suite.
Exceptional skills in critical thinking, problem-solving, and technical decision-making.
Client-facing communication skills with the ability to explain design decisions to both technical and non-technical audiences.
Strong time-management and leadership abilities to guide teams and meet deadlines.
Preferred Skills
Equipment selection experience across commercial and industrial building systems.
Demonstrated ability to manage personnel resources—motivating, developing, and directing teams.
Experience with multi-sector projects: retail, grocery, power centers, multifamily, industrial, senior living, restaurant, and convenience developments.
Compensation & Benefits
Competitive salary sign-on bonus.
Relocation assistance available for qualified candidates.
Generous PTO policy (we believe in real vacation time!).
401(k) with company match – yes, it’s strong.
Superior health benefits for you, your family, and your pets.
100% company-paid license renewals and professional memberships.
Tuition reimbursement and continued-education support with lunch-and-learns and industry conference attendance.
Casual, “uncorporate” culture – jeans and Hey Dudes welcome.
Fully staffed Permitting Department to streamline jurisdiction approvals.
Expert in-house Designers & CA department to keep your projects moving despite weather or obstacles.
Charity events, employee discounts, and flexible work perks.
Hybrid work options available based on project needs.
