You’ll lead by example, ensuring operations are carried out in accordance with relevant site procedures, Heidelberg Materials UK policies and the Health and Safety at Work etc. Act 1974.

You’ll also help ensure that environmental requirements covering areas such as waste, water discharge and dust emissions are followed correctly.

You’ll ideally have:

• Previous experience within concrete, batching, aggregates, construction, manufacturing or a similar heavy industrial environment

Why join us at Sizewell?

This is an opportunity to take your operational experience into a challenging and high-profile environment where safety, quality and teamwork are essential.
