Here’s what you’ll do:
- Deliver: Build hydraulic models and perform verification of sewer networks; run integrated model development, support with the scoping and planning of projects including flow survey verification, and development of catchment scale strategic solutions for flooding and pollution risks.
- Expertise: Deliver technical innovation including application of new technologies; problem solve for our clients and develop scopes and tender responses.
- Documentation: Prepare and deliver technical reports, presentations, and documentation to communicate modelling findings effectively using strong communication skills.
- Lead: Mentor and support other team members as part of their professional development and foster positive client relationships.
- Quality: Act as a checker of hydraulic models, calculations, and technical reports, to ensure a quality team delivery, and compliance with modelling specifications.
