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.
What You’ll Do
Mix, pour, vibrate, cure, fire, QC, and package refractory E-Brick heating elements as part of the Manufacturing team
Prepare molds for casting, including cleaning, assembly, and repair
Prepare and document Quality Assurance (QA) and Quality Control (QC) samples for each production batch
Identify, design, and implement process improvements that increase throughput, consistency, and quality
Write and revise standard operating procedures (SOPs) for casting, mold preparation, and lab equipment
Keep the production area, samples, tooling, and materials clean, organized, and cataloged
Execute a capstone engineering project with direct impact on company operations
Travel: No travel is anticipated for this role.
What You'll Bring
An enthusiastic approach and resilience in the face of challenging technical problems
Experience with hands-on work in a professional or educational setting, such as lab work, production, or construction
Attention to detail and strong communication skills
Demonstrated commitment to adhering to workplace safety procedures and contributing to safety culture
Comfort working with your hands; comfort working with power tools or heavy machinery
Ability to lift and carry 50lb material bags, stand for extended periods, and work in personal protective equipment
Proficiency with Microsoft Excel or similar data management tools
Proficiency with 3D CAD software (e.g., SolidWorks, Onshape, or Fusion 360)
Hands-on experience with additive manufacturing (FDM or SLA 3D printing), including design for printability and polymer material selection
Coursework or project experience designing fixtures, tooling, or material-handling hardware
Experience with process improvement or operational efficiency initiatives

What We Do
Imagine industry, without combustion. At Electrified Thermal Solutions, we've re-invented the firebrick to electrify industrial heat. Developed over almost a decade at MIT, our electrically-conductive firebricks are the heart of our thermal energy storage systems (Joule Hives) that provide low-cost heat to even the hottest industrial applications.
