About The Role

Be part of this ‘once in a generation’ project that will deliver clean energy to 6 million homes for the next 60 years. Sizewell C will see the creation of a 3.2 Gigawatt nuclear power station on the Suffolk coast to provide reliable, low-carbon electricity.

The Civil Works Alliance is an extended delivery enterprise involving Sizewell C and three international construction companies: Balfour Beatty, Bouygues Travaux Publics, and Laing O’Rourke.

We are more than just an alliance, we are bringing together a single delivery organization with years of learning and experience from other major complex infrastructure programs worldwide.

What you'll be doing

The Civil Works Alliance (CWA) is delivering the critical civil works for the Sizewell C nuclear power plant project. Within the Marine and Tunnel (M&T) portion, we are seeking a Sub Agent to join our marine preconstruction team in London initially ahead of mobilization to Suffolk.

This role offers the opportunity to be part of a dynamic alliance of world-class contractors, working on one of the UK’s most significant infrastructure projects.

Reporting to the Marine Preconstruction Manager for the Marine and Tunnel Portion, the Sub Agent will play a key role in developing construction methods, assessing delivery risks and opportunities, and ensuring readiness for offshore dredging, rock placement, heavy lifting, monopile installation, drilling, and grouting campaigns in the North Sea.

Who we're looking for

Essential

  • Experience within a marine or preconstruction environment.
  • Experience working within a contractor or principal contractor organization on engineering or construction projects.
  • Good appreciation of program, cost, and risk considerations during project planning and delivery.
  • Strong organizational skills, with the ability to manage multiple tasks and interfaces simultaneously.
  • Effective communication skills and the ability to work collaboratively with colleagues, designers, subcontractors, and clients.
  • Ability to take ownership of assigned tasks and deliver them with limited supervision.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
