About this role
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.
About the Role
The Manufacturing Engineering Intern supports pilot production of the E-Brick refractory heating elements at the core of our Joule Hive™ thermal battery. The role is deliberately hands-on, combining regular casting and finishing of refractory elements, mold preparation, and an independent capstone engineering project with direct impact on company operations.
Your work will tangibly deepen our understanding of producing our elements at scale. You will report to the Manufacturing Engineer.
