Senior Process Engineer – Water Treatment

Senior Process Engineer – Water Treatment

Join Stantec as a Senior Process Engineer – Water Treatment. This role focuses on water and steam specialty design for thermal in-situ SAGD facilities, heavy oil processing, and mineable oil sands.

Stantec is seeking Senior Process Engineers to work independently on complex projects and serve as team leads on larger assignments. You will lead, evaluate, select, specify, and engineer processes or methodologies for projects, performing simulations, calculations, and field work.

• Engineering design activities for projects of various sizes and complexities, delegating to Intermediate and Junior Process Engineers and mentoring them.
• Provide strong technical knowledge and leadership to design, execute, and validate all process engineering deliverables for heavy oil/SAGD projects.
• Lead delivery of process engineering requirements to conduct concept design studies and feasibility studies, pre‑FEED, FEED, and detailed engineering design.
• Complete tasks in a timely, thorough, and organized manner. Tasks may include, but are not limited to: development and review of process simulations using HYSYS, development of heat and material balances.
• Development and review of engineering drawings such as PFDs and P&IDs.
• Generate and document hydraulic analysis results and study reports.
• Perform adequacy checks and evaluation of new and/or existing equipment.
• Sizing calculations for equipment, lines, and instrumentation.
• Document calculations performed.
• Generate documents such as heat & material balance tables, line designation tables, PSV lists, SDK/cause-and-effect diagrams, set point lists, car seal lists, operating philosophies, equipment datasheets, and instrumentation datasheets.
• Participate in PHAs (HAZIDs, HAZOPs, LOPAs, and other critical safety reviews).
• Collaborate with other engineering disciplines to deliver quality products to clients.
• Client interface – discussion and presentations are mandatory requirements.

• Knowledge of process engineering design for high‑purity industrial water, wastewater treatment, heavy‑oil water treatment, steam production of SAGD/oil sands facilities, and oil & gas facilities.
• Experience in process water chemistry, including modeling of water treatment.
• Experience with energy transition/renewable energy studies (carbon capture, hydrogen, biofuels, biogas, etc.) is an advantage.
• Strong knowledge of Aspen HYSYS; familiarity with Promax, HYSYS Dynamics, Aspen Plus, Symmetry (VMGSim), AFT‑Fathom, Impulse, and others is an added advantage.
• Experience in flaring simulations using Aspen Flare Analyzer.
• Strong experience with the development, interpretation, and checking of PFDs, P&IDs and other process deliverables. Ability to read piping isometrics and plans.
• Strong experience reviewing vendor information and generating TBE.
• Very proficient with process calculations and Microsoft Excel.
• Comprehensive knowledge of design guidelines (API standards, AER directives, etc.).
• Experience with electronic markup software such as Bluebeam.
• Ability to collaborate in a project team setting and engage in creative and critical thought.
• Excellent oral and written communication skills.
• Requires a superior understanding of the Microsoft Office Suite.

• Bachelor’s degree in Engineering or equivalent, preferably Chemical or Mechanical Engineering.
• Minimum of 15–20 years of experience, with an EPC background.
• Registration with APEGA as a P.Eng. is required; registration in other jurisdictions is an asset.
