Amentum, a global engineering and technology services firm, plans to hire 3,000 staff in the UK over the next four years, driven by growth in nuclear power and defence projects.
The company is a key partner on Hinkley Point C and Sizewell C nuclear stations and contributes technical support for small modular reactors and fusion research. It is expanding UK operations to meet projected demand, aiming for a 50% increase in headcount. Investments in digital engineering, AI, and automation are also planned to enhance delivery of critical infrastructure projects.
In defence, Amentum provides safety and technology services for the Royal Navy’s nuclear submarines, manages the UK training estate for the Defence Infrastructure Organisation, and offers programme management and engineering support for the Atomic Weapons Establishment.
Stronger UK–US coordination in nuclear technology is expected to support future capacity growth and skills development in the sector, reinforcing the company’s cross-Atlantic operations.
The expansion highlights opportunities for skilled engineers, project managers, and technical specialists across energy and defence sectors, reflecting broader government investment in nuclear power and national security infrastructure.
