• Design and oversee erosion control and river/creek bank stabilisation schemes.
• Deliver bridge and culvert designs, including survey, submittal/shop drawing and construction reviews.
• Coordinate permits and work closely with federal/state/local agencies, clients and stakeholders.
• Mentor junior engineers and support team growth.

Qualifications

• Bachelor’s degree in Civil Engineering (or related discipline).
