Mechanical Engineering

About the company 

General Matter enriches uranium.

We are designing, building, and operating the world’s lowest-cost enrichment services, here in the US.  

In the process, we are restoring America’s ability to produce nuclear fuel to power AI, advanced manufacturing and critical industries our country relies on to remain competitive. 

Fuel drives the cost of advanced reactor electricity production, and enrichment drives the cost of the fuel that advanced reactors consume.  Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way.

Our mission is to make nuclear not only the cleanest and safest source of baseload power, but also the most affordable.  We believe abundant nuclear energy will lead to a post-scarcity society. 

We were incubated inside Founders Fund, like Anduril and Palantir before us, and are backed by over a dozen of the world's top venture capital firms.  

Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production.  

We are a mission-driven company with a culture of urgency, accountability, and transparency. 

Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable. 

About This Role

We’re looking for a Mechanical Engineer (Intern) with a strong interest in HVAC and building mechanical systems to join our growing engineering team. You’ll work alongside experienced engineers to design, model, and analyze air‑conditioning, ventilation, and hydronic systems for a wide range of commercial and industrial projects. This is a great opportunity for a motivated student who’s passionate about energy efficiency, indoor environmental quality, and the integration of mechanical systems in the built environment.

Responsibilities

• Assist in the design and analysis of HVAC systems using Revit, AutoCAD, and energy modeling tools.
• Support load calculations, equipment sizing, airflow, psychrometrics, and hydronic design layouts under senior engineer guidance.
• Learn to participate in system modeling and simulation using BIM workflows and performance tools such as IES.
• Observe and help coordinate with architectural, nuclear experts, structural, and electrical teams to ensure design integration and constructability.
• Help in preparing construction documents, specifications, and as-built documentation.
• Contribute to design automation efforts using visual programming (Dynamo, Grasshopper) or coding (Python, C#).
• Communicate technical concepts clearly and effectively to multidisciplinary teams.
