• Assist leadership with task breakdowns, workload estimates, and hour forecasting as needed
• Train, lead, and mentor junior designers or staff new to the project

• 10-15+ years of progressive CAD drafting and design experience supporting mechanical and/or chemical/process systems
• Extensive experience using AutoCAD and Revit for modeling and drafting
• Strong proficiency with Navisworks for model review and coordination
• Experience designing building mechanical systems in semiconductor or similar high-tech manufacturing facilities
• Demonstrated ability to lead wet-side or dry-side design efforts on large programs
