Job description

Senior Tunnel Engineer

We are seeking an experienced Senior Tunnel Engineer to lead the technical delivery of complex tunnelling and underground infrastructure projects. This is an excellent opportunity for a knowledgeable professional to contribute to major transport, water, utilities or civil engineering schemes, working across project development, design and construction.

You will provide technical leadership throughout the project lifecycle, ensuring that tunnel designs are safe, buildable, cost-effective and compliant with relevant standards. The role will involve close collaboration with clients, contractors, designers, geotechnical specialists and other engineering disciplines, as well as supporting less experienced team members.

Key responsibilities

• Lead and manage the preparation, review and approval of tunnel designs, specifications, calculations and technical reports.
• Provide expert advice on tunnelling methods, temporary works, underground structures, ground conditions and construction sequencing.
• Coordinate multidisciplinary design activities and resolve technical interfaces, risks and buildability issues.
• Contribute to feasibility studies, optioneering, tender submissions, cost assessments and project planning.
• Review contractor proposals, method statements, design submissions and technical queries during construction.
• Monitor quality, health and safety, environmental performance and compliance with applicable legislation and standards.
• Build effective relationships with stakeholders and represent the engineering team at meetings and technical workshops.
• Support the development of engineering standards, processes and junior staff.

About you

You will be a professionally qualified civil or tunnelling engineer with substantial experience delivering underground infrastructure projects. A strong understanding of tunnel design principles, construction techniques, geotechnical conditions and risk management is essential. Experience with immersed, bored, sprayed concrete-lined, cut-and-cover or mined tunnels would be advantageous.

You should be confident managing technical workstreams, communicating with stakeholders and making sound engineering judgements under programme and commercial pressures. Experience using relevant design software and producing clear, accurate technical documentation is expected. Chartered status, or active progress towards chartership, would be desirable.

What is offered

The role offers varied project exposure, professional development opportunities and the chance to influence the delivery of technically challenging infrastructure. A competitive salary and benefits package will be provided, with flexible working arrangements available where project requirements permit.
