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 Test Engineer, you will design, develop, and maintain custom testing solutions for our in-house developed electronics and electro-mechanical hardware. Testing is a necessary quality check during development hardware bring up and will be a critical last line of defense before our hardware is installed in production. This person will be needed to create test systems and infrastructure including hardware, software, and test sequences to exercise all possible failure modes.

If you seek high-impact and are excited by fast-paced, intense, Skunkworks-style projects, we encourage you to reach out to join our team.

Responsibilities:

  • Develop, design, and maintain custom test solutions for in-house developed electronics and electro-mechanical hardware.
  • Select commercial-off-the-shelf hardware and/or design PCBAs to power units, measure signals, and apply operating loads.
  • Write automation software in Python to interact with test article, test equipment, instrumentation, and production documentation systems.
  • Work closely with responsible design and manufacturing engineers to drive reliability and efficiency upgrades.
  • Root-cause test anomalies and support implementation of mitigations.
  • Design test campaigns to ensure hardware meets lifetime, performance, and safety requirements.

Basic Qualifications:

  • Evidence of exceptional ability (prior projects, portfolio of work, completed products, etc).
  • Bachelor’s degree in computer engineering, electrical engineering, or an engineering discipline with an emphasis in electrical engineering and electronics.
  • 1+ years of experience with electronic hardware development or software development.
  • 1+ years of programming experience using Python or Embedded C/C++.

Preferred Skills and Experience:

  • Experience analyzing circuits and developing functional test plans.
  • Experience designing and troubleshooting PCBAs.
  • Experience with test equipment such as oscilloscopes, DMMs, and DAQs.
  • Understanding and experience in environmental testing such as HALT, vibration, shock, thermal, and EMI/EMC.
