• Collaborate with multidisciplinary teams to ensure designs meet applicable engineering codes, project requirements, and regulatory standards.
• Contribute technical expertise during the planning, design, and construction phases of tunneling projects, including design reviews, constructability assessments, and value engineering.
• Provide leadership and mentorship to junior engineers and field staff, fostering a culture of safety, innovation, and continuous improvement.
• Participate in client meetings, technical presentations, and progress reporting as required.

• Bachelor’s degree in Civil Engineering, Geotechnical Engineering, or a related discipline.
• Professional Engineer (PE) license required.
• Minimum of 10 years of progressive experience in tunnel engineering, including design, construction, and oversight of TBM projects.

• Familiarity with relevant industry codes and standards (e.g., AASHTO, ASTM, FHWA, ITA).
• Excellent communication, leadership, and problem‑solving skills.

• Master’s degree preferred.
• Experience working on large‑scale infrastructure or transportation projects such as subways, railways, highways, or water conveyance tunnels.
