Geotechnical / Tunnel Design - (Egypt) - 100% (m/f)

We are seeking a Geotechnical / Tunnel Design Engineer with proven experience in the design of geotechnical works, underground structures and major infrastructure projects. The successful candidate will independently deliver defined tunnel and underground structures design packages while coordinating technical interfaces with multidisciplinary teams.

The role is suited to an engineer with a solid technical foundation in tunnel and geotechnical engineering who is capable of managing assigned design scopes, preparing technical deliverables, and supporting the development of junior team members..

Responsibilities

• Independently prepare geotechnical and structural design packages for tunnel and underground works, including TBM tunnels, NATM / drill-and-blast tunnels, shafts, portals, cross passages, underground stations, and cut-and-cover structures.
• Perform and document engineering calculations for excavation support systems, tunnel linings (segmental linings or cast in-situ), primary and secondary support systems, ground support measures, and ground-structure interaction.
• Develop, analyse, and interpret numerical models using software such as PLAXIS, Rocscience RS2/RS3, Midas FEA, FLAC, Abaqus, or similar tools.
• Prepare and coordinate design reports, geotechnical interpretative reports, specifications, BOQs, technical submissions, and design deliverables.
• Review geotechnical investigation data, geological models, laboratory testing results, groundwater assessments, and design parameters to support project development.
• Coordinate technical interfaces with geotechnical, structural, civil, BIM/CAD, MEP, and construction teams.
• Prepare responses to client comments, technical review comments, RFIs, and design queries.
• Undertake settlement assessments, tunnel impact studies, instrumentation and monitoring evaluations, and construction-stage engineering assessments.
• Contribute to constructability reviews, risk assessments, value engineering exercises, and support-class development.
• Review and provide guidance on work produced by Junior and Assistant Engineers.
• Participate in client meetings, technical workshops, and multidisciplinary design reviews.
• Ensure assigned deliverables meet project schedules, quality requirements, and applicable codes and standards

.

Qualifications

• Bachelor's degree in Geotechnical Engineering, Tunnel Engineering, Civil Engineering, or Mining Engineering.
• Master's degree in Geotechnical Engineering, Underground Structures, Rock Mechanics, or Tunnel Engineering is advantageous.
• 5 to 8 years of relevant experience in tunnel engineering, geotechnical design, underground structures, or major infrastructure projects.
• Demonstrated experience in the design of tunnels, shafts, portals, underground stations, cross passages, temporary works, or excavation support systems.
• Strong understanding of soil mechanics, rock mechanics, settlement assessment, tunnel support systems, and underground construction methods.
• Proficiency in geotechnical and tunnel analysis software such as PLAXIS2D/3D, the rocscience suite of software (especially RS2/RS3 UnWedge, DIPS and RocLab), Midas FEA, FLAC or equivalent.
• Experience preparing and coordinating engineering calculations, reports, specifications, drawings, and technical submissions.
• Familiarity with international tunnel and geotechnical design standards and guidelines.
• Experience working within BIM-enabled project delivery environments.
• Strong technical writing, communication, and coordination skills.
• Fluent written and spoken English; French or Turkish language capability is an advantage.
• Middle East and international underground infrastructure project experience is preferred.

We Offer:

• Young, motivated, and a healthy working environment
• Interesting opportunities for personal and professional development and growth.
• External Training Programs within our Global Branches
• Social and individual health insurance
