Water Resources (Drainage) Designer

Overview Be part of AtkinsRéalis' Water Resources team in Ontario, where engineering expertise, innovation, and collaboration come together to deliver sustainable infrastructure solutions. This role supports a wide range of municipal and transportation projects and offers exposure across all phases of project delivery. It is an excellent opportunity to grow your engineering career while contributing to projects that make a meaningful impact on communities.

Your Role

Support both simple and complex water resources studies, modeling, and design tasks across all project phases, including conceptual design, preliminary design, detailed design, construction, and operational support.

Contribute to transportation and municipal projects including highway and roadway drainage design; storm sewer systems, culverts, ditches, and channels; stormwater management (SWM) infrastructure planning; and floodplain mapping and erosion assessments.

Assist with hydrologic and hydraulic modeling of stormwater runoff and floodplains, including design and assessment of SWM controls and flood mitigation strategies; culverts, storm sewers, and road/highway drainage systems; and Low Impact Development (LID) features.

Use PCSWMM and HEC RAS to analyze system capacity, flood risk, and infrastructure performance, and prepare conceptual and detailed design drawings using AutoCAD and Civil 3D, ensuring accuracy, constructability, and compliance with standards.

Analyze, interpret, and present modeling results in technical reports, design briefs, and presentations, and support the preparation of stormwater master plans, drainage reports, and related technical documentation.

Conduct field investigations to verify existing SWM infrastructure, surface drainage patterns, and site conditions.

Collaborate with intermediate and senior engineers, modelers, project managers, and multidisciplinary teams, and coordinate with municipalities, MTO, and conservation authorities.

About You
