Independent Assessor Opportunity with the Civil Works Alliance (CWA), Supporting Sizewell C
As part of the CWA (Civil Works Alliance), you will support the building of Sizewell C. Sizewell C will be a 3.2-gigawatt power station generating low-carbon electricity for around 6 million homes and will play a key role in our energy future, supplying reliable, clean electricity for at least 60 years. This role will be within the CWA Wide Section.
What will you do?
The Independent Assessor is responsible for delivering independent assurance and audit activities across Civil Works Alliance (CWA) scopes, including civils, manufacture, fabrication, tunnelling and offshore works.
The role operates independently of the Civil Works programme’s delivery sections, providing objective, evidence-based assessments of compliance with the CWA Quality Management System, Sizewell C requirements, regulatory obligations, and nuclear industry standards.
The postholder ensures that:
- Quality risks are identified early through risk-based assurance
- Supply chain and project teams are subject to robust, independent challenge
- Nuclear safety culture, CFSI controls, and critical-to-quality requirements are consistently applied and effective.
The role supports assurance across the full project lifecycle, from pre-award supplier assessment and mobilisation through to manufacture, fabrication, construction, installation and final handover. The activity of the postholder consists in a second line of defence-in-depth, tasked to provide good governance and confidence in delivery outcomes.
Principal Accountabilities, Activities and Decisions
- Deliver independent audit and assurance assessments across civils, manufacture, fabrication, tunnelling and offshore scopes, aligned to scopes’ risk profile and safety classification, in line with CWA CQAP requirements.
- Conduct supplier audits, surveillance and governance reviews, including pre-award assessments and mobilisation readiness.
- Driving visibility, tracking and closure of quality enablers and residual actions to support readiness for scope’s release and client or regulator’s permission where applicable.
- Provide independent, evidence-based challenge to programme and supply chain teams to ensure compliance with CWA Quality Management System; ISO 9001 / ISO 19443 requirements and SZC’s and ONR’s requirements.
- Demonstrate alignment between project assurance arrangements and the Hold Point process, so that quality evidence forms a coherent and reliable basis for SZC’s decision-making and regulatory engagement.
- Identify systemic weaknesses and lead or recommend targeted improvement actions, in collaboration with Subject Matter Experts.
- Contribute to the development of risk-based audit and independent assurance strategies across the programme.
- Support cross-project learning by identifying common themes, trends and improvement opportunities.
- Promote a strong Right First Time and nuclear safety culture mindset through independent oversight.
- Supporting the business unit external accreditation process to ensure it can operate in its chosen sector.
