Role description: As part of our continued growth in Western Canada, we are seeking a motivated and technically capable Senior Hydrogeological Site Engineer to support our site-based construction supervision team in Vancouver. This role is ideally suited to an engineer with strong field experience who enjoys working directly with contractors, inspectors, designers, environmental specialists, and clients to deliver large and complex infrastructure projects. The Senior Hydrogeological Site Engineer will play a key role in the delivery of Engineering Services During Construction (ESDC), assisting with field reviews, hydrogeological monitoring, technical coordination, QA/QC verification, contractor submissions, and project documentation. The successful candidate will be a highly visible presence on site and will work closely with the Resident Engineer and design teams to ensure that construction activities are completed safely, efficiently, and in conformance with the design intent, project specifications, permits, and applicable codes.
