About the role
Be part of a once-in-a-generation infrastructure project that will help power 6 million homes with clean, reliable energy for decades to come.
Sizewell C Nuclear Power Station is a landmark development on the Suffolk coast, delivering a 3.2GW nuclear power station that will play a critical role in the UK’s low-carbon future.
The project is delivered through the Civil Works Alliance, bringing together world-class expertise from major global infrastructure programmes. Within this, the Geotechnical Sub Alliance (GSA) is responsible for delivering complex ground engineering works, including piling, ground improvement and diaphragm walls, from January 2026 to mid-2028.
As a Plant Assistant, you’ll play a key role in supporting the Deputy Plant Manager and wider plant team to deliver efficient, reliable and compliant plant services across multiple geotechnical sites. You’ll help ensure that plant hire, servicing and maintenance activities are well coordinated, accurately recorded and aligned with project requirements.
This is a site-based role offering exposure to large-scale plant operations within one of the UK’s most significant infrastructure programmes, with excellent opportunities to develop your technical and commercial understanding of plant management.
What you'll be doing
In this role, you’ll support the coordination and administration of plant hire, servicing and operational activities across the GSA sites, helping to keep site teams fully equipped and productive.
You’ll process plant hire requests from site teams, maintain accurate hire and utilisation records, and liaise with internal plant teams and approved external suppliers to arrange deliveries, collections, servicing and repairs. You’ll assist with obtaining quotations and managing external hire agreements in line with CPA contract terms.
You’ll gather and manage weekly inspection forms, delivery inspections and PUWER logs, ensuring that service schedules, certifications and compliance documentation are kept up to date. By tracking maintenance and inspection requirements, you’ll help ensure all plant remains safe, reliable and fit for purpose.
You’ll coordinate repair activities for faulty or damaged equipment, responding promptly to breakdowns and arranging suitable replacements where required. You’ll also support the onboarding of new plant assets, including tagging, documentation and system updates.
Working closely with procurement and logistics teams, you’ll help deliver timely and cost-effective plant provision. You’ll contribute to continuous improvement initiatives, support audits and inspections, and ensure all plant-related data is handled in line with GDPR and internal policies.
Who we're looking for
We’re looking for an organised, detail-focused and proactive individual who enjoys working in a busy operational environment and takes pride in delivering high-quality support.
You’ll ideally have experience in plant hire, plant administration or customer support within construction or a related industry, along with a good understanding of plant servicing, maintenance and compliance requirements. Familiarity with CPA contract terms and external hire procedures will be highly beneficial.
You’ll bring strong communication and organisational skills, enabling you to work effectively with site teams, suppliers and internal stakeholders. You’ll be comfortable managing multiple priorities and responding quickly to changing operational demands.
You’ll be confident using Microsoft Office, particularly Excel, Word and Outlook, and have experience working with plant management systems such as Insphire or MCS. A practical understanding of plant operations and repair processes within a construction setting will support your success in this role.
Most importantly, you’ll demonstrate a collaborative mindset, a commitment to safety and quality, and a genuine desire to contribute to a nationally significant project that will leave a lasting legacy.
