• Engineering Calculations: Execute load calculations, air distribution sizing, boiler/chiller plant design, pump and piping layouts, and steam routing.
• Bid Support & Modeling: Develop schematic designs and CAD/Revit models during the bidding phase to help estimating teams establish precise labor and material costs.
• Client Presentation & Scope Drafting: Draft technical proposal letters and present engineering concepts directly to building owners, general contractors, and plant managers.
• Plan Review & Compliance: Coordinate construction drawings and arrange state/local plan reviews, ensuring full compliance with regional mechanical and energy codes.

What We Are Looking For (Requirements & Qualifications)

• Education & Professional Credentials: Bachelor’s Degree in Mechanical Engineering (BSME), Registered Professional Engineer (PE), or a State-Licensed HVAC Designer.
• Industry Experience: 3+ years of hands‑on commercial/industrial HVAC design experience, ideally developed within a fast‑paced mechanical contractor setting.
• Software Fluency: Proficiency using AutoCAD, Revit, specialized HVAC load calculation software, and Excel.
• Client-Facing Presence: Outstanding presentation skills and comfort collaborating directly with project executives, facility managers, and vendor partners.
• Site Mobility: Valid driver’s license and ability to execute site walkthroughs (climbing ladders, accessing mechanical spaces) within ~1 hour of the Fox Valley area.

Preferred Technical Assets (Bonus Skills)

• Mechanical Contractor Background: Prior experience working directly for an industrial or commercial mechanical contracting firm.
• Industry Certifications: Certified Energy Manager (CEM) or LEED AP accreditation.
• Cross-Functional Knowledge: Familiarity with industrial ventilation, steam systems, heavy ammonia refrigeration, or commercial plumbing codes.
