Principal Engineer- Tunnel Practice (Canada)

Description

• Lead and independently organize work plans, design tasks, and deliverables for medium- to high-complexity tunneling and underground projects.
• Review and supervise the work of intermediate engineers and mentor interns, especially on numerical modelling tasks.
• Contribute geotechnical and structural expertise for underground components on major water conveyance projects, including long microtunnels drives and deep shafts.
• Contribute to the development and continuous improvement of AECOM’s tunneling standards, tools, and best practices.
• Coordinate multidisciplinary design inputs, including tunnelling, geotechnical, hydrogeological, structural, civil, utilities, hydraulic, traffic, environmental, procurement, cost, and schedule disciplines.
• Design SOE systems for deep shafts, pump stations, portals, cut-and-cover structures, and deep excavations.
• Provide technical input for tunnel and shafts design methodologies, means and methods, and proposal development.
• Collaborate closely with internal disciplines, external partners, and clients to support successful project delivery.
• Participate in constructability reviews, value engineering workshops, and risk management activities.
• This role will function as a Deputy Design Manager, supporting the Design Manager in the planning, coordination, and delivery of multidisciplinary design packages for a deep sanitary sewer tunnel system within a dense urban corridor.
• Provide expert guidance in soil mechanics, rock mechanics, and ground–structure interaction to multidisciplinary project teams.
• Design tunnels using MTBM and SEM/NATM.
• Prepare contract documents, design reports, technical specifications, and drawing packages.

Requirements

• BA/BS + 6 years or more of relevant experience or demonstrated equivalency of experience and/or education.
• Familiarity with water and wastewater design standards in the Region of Peel, City of Toronto, York Region, and Halton Region is considered an asset.
• Proficiency in analytical and numerical methods for underground works, including 2D/3D modelling.
• Master’s Degree in Geotechnical or Structural Engineering.
• Strong knowledge of geology, hydrogeology, rock mechanics, and ground behavior.
• Hold a P.Eng. in ON or have the ability to obtain it within one year from starting of employment.
• Ability to work independently and make informed technical decisions with minimal supervision.
• Strong teamwork, coordination, and client-facing skills.
• Experience with design management of water conveyance projects.
• Strong technical capabilities in underground design and numerical analysis.
• Excellent written and verbal communication skills, including the ability to present technical concepts clearly.
• The position is suited to a technically strong engineer with proven experience in design delivery, coordination, and risk management for major municipal infrastructure programs.
• Experience with both large-diameter (5m+) tunneling and trenchless technologies.
• Technical expertise in TBM tunneling, SEM/NATM, shaft design, ground improvement, and deep excavation support systems.
• 6 years of experience with design management of water conveyance tunneling projects.
• 6+ years of experience in tunnels and microtunnels design, deep shafts, underground structures, and geotechnical/structural analysis for major infrastructure programs (highly preferred).
