Project Support jobs in United Kingdom

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 bring together a single delivery organisation with years of learning and experience from other major complex infrastructure programmes worldwide. We are searching for a Senior Process & Accountability Manager to join the CWA (Civil Works Alliance), as we take on one of the UK’s most ambitious infrastructure projects—supporting the delivery of Sizewell C. This 3.2‑gigawatt power station will generate low‑carbon electricity for six million homes and play a crucial part in our sustainable energy future for decades to come. If you excel at turning complexity into clarity, embedding accountability, and driving real change across large organisations, we want to hear from you.
