Are you ready to take ownership of complex mechanical systems that play a vital role in managing the UK’s nuclear legacy? What if your next role gave you the opportunity to work across everything from pumps and process equipment to nuclear fuel handling and cutting‑edge decommissioning technology? At Hinkley Point A, this is more than a mechanical engineering role it’s your chance to make a real impact in a highly regulated, safety‑critical environment.

As a Mechanical System Engineer, you’ll manage a diverse portfolio of plant and systems while contributing to the development of innovative decommissioning solutions. With full support to build your nuclear expertise, you’ll grow into a trusted technical authority, shaping how major infrastructure is safely maintained, enhanced, and ultimately retired.

What will you be doing

  • You’ll take the lead in managing and optimising a range of mechanical systems, ensuring they perform safely, reliably, and in line with strict regulatory requirements.
  • Acting as the focal point for your assigned assets, you’ll develop and deliver engineering strategies that drive long‑term performance while identifying opportunities for maintenance improvements and investment.
  • From leading inspections and analysing performance data to supporting modifications and new equipment designs, your work will have a direct impact on both current operations and future decommissioning projects.
  • You’ll collaborate with multidisciplinary teams, providing expert guidance and ensuring smooth delivery of engineering changes across the site.

  • You’re a capable and driven mechanical engineer who thrives in a hands‑on, complex environment and is motivated by real ownership and responsibility.
  • You bring experience from an industrial or plant‑based setting and are confident working within structured engineering standards and safety frameworks.
  • You’re equally comfortable analysing technical challenges and collaborating with stakeholders to deliver practical, high‑quality solutions.
  • You’ll have a strong engineering foundation, with at least an HNC (or equivalent) and ideally a degree in mechanical engineering, along with experience in a practising mechanical engineering role on industrial plant.
  • Experience in nuclear or conventional plant operations, as well as a solid understanding of engineering standards and stakeholder engagement, is essential.
  • Any progress toward professional accreditation, alongside experience in regulated environments, safety cases, or risk assessment, will further strengthen your profile.

Qualifications

  • A recognised engineering qualification (minimum HNC or equivalent, ideally degree‑level) with experience in mechanical engineering on industrial plant.
  • Experience in nuclear or conventional plant environments, with a strong understanding of engineering standards and compliance.
  • Proven ability to work with internal and external stakeholders in a collaborative, safety‑focused setting.
  • A commitment to professional development, with interest in chartership or further technical progression.

We also welcome applicants who are still developing their experience. If you have the right foundation and ambition, you’ll be supported with a structured development plan, giving you a clear pathway to grow into the full responsibilities of the role.
