Work for Powervault: Customer Service Engineer


We are a new and rapidly expanding company who design and manufacture an IoT cleantech product, Powervault, which helps UK home owners store and use electricity more efficiently. The Company requires a highly talented, efficient and proactive Customer Service Engineer to join the team and support end users and installers service and manage our network of Powervault installations around the UK. This will provide the successful candidate with the opportunity to work in one of the fastest-growing and exciting sectors in the cleantech / low carbon energy industry.

The Company

Powervault is the UK’s first company to offer an electricity storage system to homeowners with PV panels to help them store and use their excess solar energy more efficiently. With the introduction of smart meters and time-of-use tariffs in the next 12-18 months, electricity storage will become a compelling proposition for all households, growing Powervault’s addressable UK market from <1 million households to >20 million. The Company’s mission is to help homeowners cut their energy bills by storing zero or low cost electricity for use at times of peak demand, whilst also reducing peak grid electricity demand and carbon emissions. Government reports suggest home electricity storage can contribute to saving UK Plc £8 – £10 billion per annum off the cost of generating and distributing electricity. Powervault’s lead product is an intelligent, cloud-connected, integrated battery and control system in an attractive home appliance-style package, and is the most cost-effective home electricity storage product on the market.

Since formation in 2013, Powervault has developed its first-generation product, filed patent applications and secured over £440,000 of grant support and prizes from Innovate UK / Technology Strategy Board, Climate KIC, Nesta and the Prince’s Trust.  In September 2014, Powervault launched its lead product and secured £150,000 in crowdfunding in under eight hours in the world’s fastest cleantech equity crowdfunding activity. Powervault has since raised two further rounds via crowdfunding, business angel and institutional investment totalling £2.3 million, which is funding the business most of the way to breakeven.

The electricity storage market is now entering an exciting new phase; high profile players like Tesla validate the opportunity. Powervault, the leading home electricity storage company in the UK, is aiming to grow rapidly towards a trade sale in the next 3-5 years to deliver a significant capital return to its investors and employee option-holders.
