The role includes sizing ductwork, plumbing, and fire suppression systems, selecting suitable equipment, and drafting and modeling these systems using AutoCAD and Revit software. The role also develops specifications in Word and Speclink, and reviews drawings and specifications to ensure accuracy. This role requires strong communication skills (both written and verbal) and a willingness to mentor other engineers and designers.

• Develop and implement solutions for hazardous area ventilation, odor control, and explosion prevention in highly corrosive or combustible environments typical of wastewater treatment.
• Use software to draft and model HVAC, plumbing, and fire sprinkler systems, and develop specifications for HVAC, plumbing, and fire sprinkler equipment.
• Interpret relevant codes and standards for fire sprinkler system design and compliance.
• Review HVAC, plumbing, and fire sprinkler drawings/specifications, coordinating with other engineering disciplines to ensure integration and compliance.
• Size ductwork, plumbing, and fire sprinkler distribution systems using industry-standard techniques and models.
• Lead large projects with limited oversight and contribute to projects of strategic importance.
• Flexibility to adapt and execute various additional assignments based on evolving needs.
• Provide mentorship, guidance, support, and knowledge-sharing to help less experienced team members develop their skills and grow within their roles.
