• Assist with master planning efforts and long-term solutions
• Conduct field visits and support construction activities
• Communicate with project teams, clients, and contractors

What We’re Looking For

• PE license (or ability to obtain within 6 months)
• Experience with GIS, Civil 3D and/or Revit preferred.
