We enjoy working together as a team and are looking to add a Civil Engineer and Interns to our team. On a typical day as a civil engineer, you may be designing roadway drainage systems, creating the horizontal and vertical geometry for a road or trail design, or assisting with the design of the signage, pavement markings, and erosion control measures necessary for project construction.
At the end of the day, the work we do helps to make our community a better place. Whether it is saving lives through safety implementation plans, improving the quality of life by constructing more trails and sidewalks, or improving the roadway for your morning commute, we love making a positive impact on our community!
