Castle Water has an exciting opportunity for an innovative Solution Designer to join our dynamic IT/Systems team and to develop and implement systems architecture that will meet business needs.

The Solution Designer’s responsibilities will include gathering requirements, analysing and translating business, information and technical requirements into an architectural blueprint that outlines solutions to achieve business objectives and documenting of functional specifications, as well as developing enterprise level designs that integrate across applications, systems and platforms. The Solution Designer must also be able to regularly update the company on any developments in systems architecture projects.

To be successful, you should be able to integrate any updated specifications and requirements into the systems architecture and to explain complex problems to all stakeholders in layman’s terms. This is not a hands-on coding role, but one of solution integrity leading to future scalability, reduction in technical legacy and support costs and enabling a digital transformation of the company offering, specifically to customers.

Castle Water is the leading independent water retailer in the UK, supplying (at September 2018) 570,000 Supply Points across England and Scotland. Castle Water is the leading supplier in London and the Thames Valley, South East England and Portsmouth, and one of the 5 largest suppliers in Scotland.

Castle Water has a track record of providing excellent customer service, and of developing innovative approaches to utility supply. We developed the first affinity partnership in the water sector, pioneered online switching by customers, and were the first company to transfer customers in England. We have more 5* reviews on Trust Pilot than all other water retailers combined. Our values include treating customers fairly and maintain an open-door approach with our regulators.
