Job Description

About Electrified Thermal Solutions

Boilers, furnaces, and kilns are the engines of our industrial economy, providing heat to melt steel, form cement, and transform chemicals. But historically reaching this high-temperature heat required burning fossil fuels, making the industrial sector responsible for 25% of global greenhouse gas emissions.


Electrified Thermal Solutions has a simple and massive goal: to electrify industry.

To do this, we are building the Joule Hive™ thermal battery: an energy storage technology that converts and stores cheap, renewable electricity as high-temperature heat. Our vision is to mitigate gigatons of CO2 emissions per year by deploying the Joule Hive™ at every industrial furnace, turbine, boiler, and kiln.


Electrified Thermal is seeking a 6-month intern/co-op to assist with pilot production of our “E-Cast” refractory heater elements, at our Medford, MA facility. Your role will be at the forefront of our effort to scale up production of these elements which form the basis of the Joule Hive ™ thermal battery. Your work will tangibly deepen our understanding of producing our elements at scale. You will report to the Senior Test Engineer.
