HR Administrator

The HPC Jobs Service supports local people into exciting, long-term careers across our Project. Hinkley Point C is the UK’s first new build nuclear power station in a generation that is critical to the UK NetZero targets. All roles on the project require key behaviours which support the Zero Harm objective, a questioning attitude, and drive to uphold the standards of safety and quality required by this prestigious project. A committed strong work ethic is essential at all levels. All candidates are expected to demonstrate their knowledge and experience where possible directly related to the criteria required for the role. It is acknowledged that previous Nuclear based experience will not always be possible, as such supporting with project research and how individual skills may be transferable will be important.

There are opportunities to put together strategic people plans within the nuclear sector, work on wider company people projects, deliver an excellent first class service to employees and ensure the administration and processes that engulf working life are implemented effectively and fairly.
