Context

It is rare to find an infrastructure project immune to budget and political cycles, but this one has a career horizon stretching all the way to 2086. We are looking for a Tunnels Lead to join the Newcastle–Sydney HSR corridor—a 100% renewable, greenfield network that is setting a new global standard for engineering excellence.

Missions/Main Duties

In this role, you will be the singular accountable technical authority for the programme's highest-cost and highest-risk workstream. From TBM running tunnels under the Sydney CBD to complex harbour crossings, you will lead the strategy that ensures our underground assets are built to last for the next century.

Profile/Skills

• Lead all underground design strategy and technical delivery across all tunnelled works, including TBM running tunnels, mined/NATM sections, and underground station excavations.

• Serve as the singular technical authority for the highest-cost and highest-risk workstream in the programme.

• Define the ground investigation and geotechnical characterisation programme, translating complex data into contractually defensible design parameters.

• Direct numerical and analytical modelling for tunnel stability, lining design, and surface settlement prediction, with a focus on sensitive receptors in urban interfaces.

• Act as the primary technical interface with the Contractor's tunnelling construction management, ensuring design reflects TBM plant capability and launch constraints.

• Attend joint ECI workshops to review construction methodology and ensure a collaborative approach to delivery.

• Maintain the tunnels risk register, owning technical mitigation for ground condition variability, groundwater ingress, and heritage structure protection.

• Co-ordinate specialist sub-leads for cross passages and portals to ensure an integrated design approach across all asset types.

• Manage the interface of tunnel design with ventilation, fire life safety, track, and systems disciplines.

If you are ready to put the "greenest thing possible" on your CV and manage a legacy workstream that moves the needle for decades to come, we want to hear from you.
