As an important addition to the tunnel and civil/structural design team in Croydon or Birmingham, you will have opportunity to work on global major projects. As a key team member with a strong technical background, you will be able to lead projects while focused on effective and reliable delivery. You will provide design and integration with other engineering disciplines including structural, geotechnical, environmental, mechanical and electrical engineers covering a range of project requirements from new build to modification, maintenance or refurbishment. You will be involved in the planning and preliminary design and constructability of underground works as well as be responsible for the production and delivery of reliable design solutions, reports, specifications or drawings. Additionally, as an integral member of the team, you'll contribute to the business and team's technical development.

Your responsibilities will involve the following:
  • Guide the team or package for design analysis, reports and drawings for main civil and underground works
  • Involvement in model and drawing production and interfaces between key elements above and below ground
  • Support or lead on technical activities for a variety of major projects including tunnel and underground work projects
  • Assist in the mentoring and guiding of early career professionals within the team.

As a Tunnel design engineer, you have a background in the structural design of tunnels for either a consultancy or contractor and are familiar working with industry standards such as Eurocodes. You've worked on multiple projects in different sectors as well as acted as the business representative when liaising with various clients. You understand design risk management, construction programming, tendering process and technical governance and have the ability to build a network or drive technical development initiatives. Additionally, you are available to travel nationally or internationally for project delivery as required.

  • Chartered with a relevant professional institution
  • Experience of methods, tools and techniques for the design and assessment of tunnel structures

  • Although not essential, industry experience in rock tunnel engineering would be beneficial as well as experience of project integration tools and working in a Common Data Environment (CDE). Any understanding or experience with geotechnical and structural analysis programmes will be advantageous as would practical experience in the construction of underground and related structures.

Our Tunnels division is one of the global leaders in tunnel planning, design and construction in all conditions from soft ground to hard rock. Having planned and designed numerous road, rail, metro, water and service tunnels across the globe including London's Thames Tideway East Tunnel, Northern Line Extension, Crossrail, the SMART road/water tunnel in Malaysia, Lesotho Highlands Water Project in Africa and the Channel Tunnel between the UK and France, we continue to be involved in many of the most challenging civil/structural and tunnel, sub-terrain, underground works and hydro-electric engineering projects.
