To expand our Water discipline, we are seeking an Associate with hydraulic design experience to serve as a Technical Authority.

Your role will be to provide technical leadership, governance, and assurance across water and wastewater treatment projects. This role will act as the subject matter specialist for hydraulic design, ensuring compliance with client standards, promoting engineering quality, and supporting the delivery of safe, efficient, and innovative solutions across a diverse portfolio of projects.

Responsibilities include:

Developing ties with others is something you do by acting respectfully and delivering on your promises. And you never get set in your ways but keep exploring new insights and ways to improve.

 

On top of that, you’ll have:
