*Vacancy: Data Scientist – Electricity Disaggregation*

*Company Introduction*
An exciting opportunity has arisen for an experienced data scientist at

Voltaware is a young and growing start up based in London, striving to
reduce energy bills and improve energy efficiency using our unique energy
monitoring service – the Voltaware energy monitor.

Voltaware have developed a sensor which uses NILM technology to measure
electricity usage in real time. Using machine learning and a disaggregation
algorithm, our sensor continually learns appliance-level electricity
consumption information. This information is sent to the Voltaware app
where end-users can understand what, where and when they are using their
energy in real-time. Voltaware can be used by homeowners and businesses
alike. Please see www.voltaware.com for more details.

*Job Description*
We are looking for a Data Scientist that will help us discover the
information hidden in the vast amounts of data collected by our sensors,
and help us make smarter decisions to deliver even better products. The
primary focus of the role will be in applying data mining techniques, doing
statistical analysis, and building high quality prediction systems
integrated with our products including (but not limited to): automated
scoring using machine learning techniques, building recommendation systems,
improving and extending the features used by our existing classifier,
developing internal A/B testing procedures, building systems for specific
applications in healthcare, elderly care, security systems, fault
detection, and preventive monitoring of appliances.

*Key points:*

   - £40,000 - £55,000 annual salary - negotiated based on experience
