Job description

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
As a Manufacturing Engineer Intern, you will gain hands-on experience developing the manufacturing processes, tools, and systems that help take new hardware from development into production. You will work alongside design and manufacturing engineers to improve the safety, performance, cost, and manufacturability of parts, systems, and assemblies. You'll spend time on the shop floor assembling hardware and test stands, troubleshooting problems, and iterating on processes based on what you learn. This is an opportunity to build practical manufacturing experience while contributing to highly reliable systems and helping drive down the cost of enrichment.
Responsibilities
  • Develop and implement scalable manufacturing processes to ensure reliable, safe systems.
  • Collaborate with design engineers and make recommendation for improved manufacturability, performance, safety, and cost.
  • Build, assemble, and validate prototypes, test stands, and development units.
  • Perform root-cause analysis on test failures and develop hardware mitigations.
  • Establish manufacturing and quality practices that scale with the company and through production phases.

Basic Qualifications
  • Current undergraduate or graduate student pursuing a degree in Mechanical, Manufacturing, Aerospace, Nuclear, or a engineering related field.
  • Familiarity with engineering drawings, CAD models, and basic GD&T concepts.
  • Collaborative team member who thrives in fast-paced, multidisciplinary environments and is eager to learn.
  • Strong understanding of engineering fundamentals.
  • Interest in hands-on manufacturing, hardware development, and working in a fast-paced technical environment.
  • Hands-on experience through coursework, student teams, internships, research, or personal projects.

Additional Requirements
  • Ability to work extended hours and weekends as necessary.
