Our Business
Workdry International is the UK’s leading provider of water pumps and industrial wastewater treatment products and services. The company operates under two complementary trading businesses and is the holding company for Selwood Ltd and Siltbuster Ltd.
With a pedigree spanning seven decades, Selwood is an innovative business with a cutting-edge approach to customer service, product development, manufacture, and quality. We are world leaders in pump manufacturing and the leading pump rental solutions company in the UK.
Siltbuster’s goal is to keep our water clean and natural; they have over twenty years' expertise in treating contaminated waters across a wide range of sectors. The Group has grown enormously over the last few years, and we need to ensure our staff have the right skills, knowledge, and experience to deliver to our customers, as well as creating career paths to help develop, retain, and motivate them.
About The Role
We are looking for a proactive HR Shared Services Administrator with a strong interest in reward and benefits to join our centralised HR function. This role is ideal for someone who enjoys detail-driven work, thrives in a service-oriented environment, and wants to develop deeper expertise in compensation and benefits administration.
You’ll play a key role in bringing our people experience to life — supporting colleagues across the business and ensuring our reward and benefits processes run smoothly and feel great.
