• Provide technical guidance on engineering geology, rock mass characterization, in-situ stress, and geotechnical design parameters.
• Define design criteria, analysis methods, excavation and support concepts, construction sequencing, and technical requirements.
• Lead technical reviews, constructability, value engineering, and risk assessments, and review key design deliverables.
• Coordinate with multidisciplinary teams and mentor engineers supporting tunnel and underground structure design.
• Serve as a technical lead and subject matter expert for major underground infrastructure, hydropower, and pumped-storage projects.
• Provide independent design review and technical assurance for complex underground structures and underground water conveyance systems.
• Support business development activities, including proposal preparation, technical presentations, and client engagement.
