About The Position

We are seeking a Senior Civil / Structural Engineer to serve as the primary CSA technical authority on the owner’s project team. This is a high‑impact, single‑point accountability role, responsible for ensuring CSA engineering quality, constructability, and compliance across all project phases. You will work closely with EPC partners, modular fabricators, and construction teams to drive technically sound decisions that protect schedule, safety, quality, and cost, while ensuring alignment with company standards and industry codes. This role will evolve from a design‑focused, office‑based position into a field‑intensive role as construction ramps up at the project site in St. Gabriel. The project integrates with an existing operating facility and includes extensive civil, structural, and architectural (CSA) scope, from geotechnical investigations and foundations to buildings, structural steel, and modular interfaces.
