System Administrator

We are currently recruiting for an experienced Systems Administrator to join the Project Controls function within the Civil Works Alliance (CWA), supporting one of the most significant infrastructure programmes in the UK: Sizewell C.

As part of the CWA, we're proud to play a critical role in the delivery of Sizewell C - a 3.2-gigawatt nuclear power station that will generate low-carbon electricity for around 6 million homes. This is a project that will help shape the UK's energy future, supplying clean, reliable electricity for at least 60 years.

This is an exciting opportunity for someone ready to lead the configuration and day-to-day administration of PMO software systems across a complex, multi-stakeholder programme. Initially based in London, this role will eventually move to site-based operations.

About the Role

You'll be responsible for making sure our PMO systems - including Primavera Unifier, PRISM, P6, SharePoint, and ARM - are secure, properly configured, and effectively used by the right people across the alliance. You'll work with functional and operational leads to align system setup with real-world business outcomes.

Whether you're managing user access, coordinating updates with software vendors, or supporting users to get the most from the tools, your expertise will directly support smarter, data-led decisions that help drive operational efficiency.

What You'll Be Doing

• Administer and maintain PMO systems across the Civil Works Alliance
• Manage user access levels and permissions to ensure secure, appropriate usage
• Collaborate with leadership to configure systems to meet evolving project needs
• Provide first-line support for system users across the alliance
• Engage closely with IT, Digital, and Software vendors to drive system improvements
• Help operational teams with varied digital maturity levels use tools effectively
• Monitor and manage risks around systems performance and integration

• Demonstrable experience in systems administration on major construction projects
• Proven track record working with Primavera Unifier (or the drive to upskill rapidly in it), PRISM, P6, SharePoint, and ARM
• An ability to translate complex technical requirements into practical business outcomes
• A delivery-focused mindset and confident communication style
• Ability to work independently, prioritise effectively, and influence diverse stakeholders
• Comfortable working in high-paced, high-stakes environments

This is a brilliant opportunity for someone ready to step into a highly influential role, supporting one of the UK's most ambitious energy infrastructure programmes.If you're excited by the idea of working at the intersection of technology, operations, and energy innovation - the CWA would love to hear from you.
