Electrical Engineer Intern - Summer & Fall 2025

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

As an Electrical Engineering Intern, you will join our engineering team and play a pivotal role in scaling up our 1 MW Commercial Demonstration Product System to a First-of-a-Kind (FOAK) 5 MW capacity. This internship offers an exciting opportunity to gain hands-on experience in renewable energy technology. This internship offers a unique opportunity to work on a cutting-edge project that will shape the future of renewable energy technology. You will report to the Lead Electrical Engineer. 

• Create a specialized sizing tool to accurately gauge the requirements of the Joule Hive Thermal Battery (JHTB) at 5 MW capacity and estimate its dimensions, thermal storage capacity, and the number of bricks needed. 
• Support optimization of thermal energy storage utilization to enhance system efficiency and performance. 
• Development of a comprehensive Computer-Aided Design (CAD) framework for the 5 MW system, including the development of models that encapsulate the system's architecture, components, and subsystems. 
• Ensure seamless coordination among various components and subsystems through the CAD framework. Collaborate with cross-functional teams to integrate and optimize various subsystems, components, and processes within the 5 MW system. 
• Maintain detailed documentation throughout the project, such as design specifications, CAD models, simulation results, and test reports. 
• Provide progress updates and technical reports to project stakeholders, highlighting key achievements, challenges, and mitigation strategies. 

• Current enrollment in a B.S. or M.S. in Electrical Engineering and successful completion of coursework in Circuit Theory 1 & 2, Signal Processing, Advance Control Systems, as well as a capstone project or any research-directed coursework
• Proficiency in Computer-Aided Design (CAD) software, such as Onshape or SolidWorks. 
• Proficiency in Microsoft office (Excel, Word, and PowerPoint).  
• Strong analytical and problem-solving skills. 
• Ability to work both independently and in a team environment with excellent communication and interpersonal skills.   
• Familiarity with Python is a plus. 
• Experience with renewable energy systems or thermal energy storage is a plus. 

• Flexible start and end dates 
• Collegial, fast-paced, and fun environment  
• Competitive hourly rate
• Hybrid work schedule after onboarding
• Five days paid time off (in addition to company holidays)
