The ideal candidate is a developing geotechnical and tunnel engineering professional with experience supporting the design of geotechnical works (including reinforced cut slopes), tunnels, shafts and major infrastructure projects. The candidate should be capable of undertaking defined design tasks with senior review while coordinating with multidisciplinary teams to deliver high-quality engineering solutions.

This role is suited to an engineer who combines solid technical skills with a proactive approach, strong organizational abilities, and a desire to further develop expertise in underground infrastructure design.

Responsibilities

• Support the design of tunnels, portals, cross passages, cut-and-cover structures, excavation support systems, shafts, and related geotechnical works.
• Prepare calculations, design assessments, and technical documentation for assigned tunnel and underground works elements under senior review.
• Develop numerical model inputs and participate in the interpretation of analysis results using software such as PLAXIS, rocscience software, Midas FEA, or similar tools.
• Prepare calculation notes, design reports, GIR inputs, BOQs, specifications, drawings, and technical submissions.
• Review geotechnical investigation data, geological models, laboratory test results, and design parameters.
• Undertake assigned settlement assessments, support design checks, and ground-structure interaction evaluations.
• Support instrumentation and monitoring assessments and construction-stage engineering reviews.
• Coordinate assigned inputs with BIM/CAD, geotechnical, structural, civil, MEP, and construction teams.
• Contribute to the preparation of responses to technical comments, RFIs, and design queries.
• Participate in constructability reviews, multidisciplinary coordination meetings, and technical workshops.
• Support quality assurance activities by checking calculations, reports, drawings, and design deliverables for completeness and consistency.
• Contribute to the delivery of projects in accordance with safety, quality, programme, and client requirements

Qualifications

• Bachelor's degree in Geotechnical Engineering, Tunnel Engineering, Civil Engineering, or Mining Engineering.
• 0 to 5 years of relevant experience in tunnel engineering, geotechnical design, underground structures, or major infrastructure projects.
• Master's degree in Geotechnical Engineering, Underground Structures, Rock Mechanics, or Tunnel Engineering is advantageous.
• Experience supporting the design of TBM tunnels, NATM tunnels, drill-and-blast tunnels, shafts, portals, cross passages, underground stations, or cut-and-cover structures is preferred.
• Good understanding of soil mechanics, rock mechanics, excavation support systems, tunnel linings, ground behaviour, and settlement assessment.
• Working knowledge of geotechnical and tunnel engineering software such as PLAXIS 2D/3D, the rocscience suite of software (especially RS2, UnWedge, DIPS and RocLab), Midas FEA or equivalent.
• Experience preparing engineering calculations, design reports, technical submissions, and project documentation.
• Familiarity with international tunnel and geotechnical design standards is preferred.
• Experience with BIM/CAD coordination, AutoCAD, Civil 3D, Revit, Navisworks, or similar digital delivery platforms is an advantage.
• Strong analytical, organizational, and communication skills.
• Ability to manage multiple tasks and meet project deadlines while working under senior guidance.
• Fluent written and spoken English; French or Turkish language capability is an advantage.

We Offer:

• Young, motivated, and a healthy working environment
• Interesting opportunities for personal and professional development and growth.
