Key Job Responsibilities:

· Support the design and development of railway tunnels and underground infrastructure across concept, preliminary, detailed, and IFC design stages.

· Prepare and develop tunnel drawings, calculations, technical reports, specifications, and other engineering documentation.

· Support the design of railway tunnels, tunnel portals, shafts, cross passages, emergency access structures, and associated underground infrastructure.

· Support tunnel engineering calculations, structural assessments, excavation and lining design, and other relevant engineering analyses.

· Coordinate tunnel designs with Civil, Structural, Geotechnical, Track, MEP, Systems, Architecture, and other multidisciplinary engineering teams.

· Review geotechnical and geological information and incorporate relevant requirements into tunnel design solutions.

· Support the design and coordination of tunnel alignment, lining systems, waterproofing, drainage, and other tunnel-related elements.

· Participate in multidisciplinary design reviews, technical workshops, constructability reviews, and design coordination meetings.

· Support the resolution of technical design issues and multidisciplinary coordination conflicts.

· Review relevant technical submissions, design proposals, RFIs, and engineering documentation where required.

· Ensure tunnel design deliverables comply with project requirements, applicable railway standards, and Sener quality procedures.

Job Requirements:

· Bachelor’s degree in civil engineering, Structural Engineering, Tunnel Engineering, or a related discipline.
