## 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 The Team

The Test Team is responsible for development, qualification, and acceptance testing of all hardware products at General Matter. We create and maintain the infrastructure and standards to support rapid hardware development.

Test Specialist:

As a Test Specialist you'll take ownership of complex testing operations from setup through execution, working independently on critical development, qualification, and acceptance campaigns. You'll collaborate directly with engineers on instrumentation strategy and data acquisition, and drive root cause investigations to resolution. This role offers the opportunity to make a tangible impact on product development by ensuring testing excellence through hands-on execution and continuous improvement of test systems. If you thrive in a fast-paced R&D environment and want to be the go-to expert for test operations, this is your opportunity to own meaningful work that directly enables engineering success.

Responsibilities:

- Work independently on projects of diverse or complex scope.
- Set up and execute tests of varying complexity across development, qualification, and acceptance campaigns
- Own test assets including Data acquisition systems (DAQ) and test stands, maintaining a test facility that is safe, clean, calibrated, and ready for future testing.
- Assist engineering on projects and tests with instrumentation, DAQ support, and best practices for DFT (design for test)
- Perform root cause investigation to drive engineering issues to closure.
- Collaborate with engineers to update test documentation and improve process
- Author and update scripts (Python, LabVIEW, Twincat) to run tests and analyze results.

Basic Qualifications:

- Evidence of exceptional ability (prior projects, portfolio of work, completed products, etc).
- Strong understanding of engineering fundamentals.
- Ability to perform trade studies and make clear recommendations using first principles and engineering fundamentals even with partial information.
- High school diploma or equivalency certificate
- 5+ years experience in test setups or technician support roles for fast-paced technical environments.

Preferred Skills and Experience:

- Experience in a fast-paced engineering or highly technical environment, with a resourceful approach to delivering under tight timelines or budget constraints.
- Extensive experience with a variety of instrumentation and data acquisition systems (load cells, pressure transducers, thermocouples, deflection transducers), input output, and scripting
- Experience with maintaining calibrations of instrumentation devices (load cells, pressure transducers, power supplies, etc.).
- Experience with light fabrication skills (welding, machining, sheet metal, drilling, mill and lathe).
- Strong focus on documentation and standards of test, instrumentation, and data acquisition systems.
- Ability to read mechanical and electrical drawings and blue prints and fabricate and repair cable harnesses including: soldering, crimping, assembling connectors

Additional Requirements:

- Physical effort including standing, lifting, and carrying equipment up to 50 lbs. unassisted
- Must be able to work all required shift hours, overtime and/or weekends as needed

## About General Matter

## Core Business
- **Primary industry**: Nuclear energy – uranium enrichment, nuclear fuel supply chain
- **Target customers**: Nuclear power plant operators (civilian reactors, small modular reactors, microreactors), data center operators, industrial manufacturers, and government/defense entities
- **Mission**: “Restore US leadership in nuclear fuel” and “make the cleanest, safest form of baseload energy the most affordable” [generalmatter.com/mission](https://generalmatter.com/mission/)

## Products & Services
- **Low Enriched Uranium (LEU)**: Enrichment of uranium to 3-5% U-235 for existing US civilian reactors (supplying ~20% of US grid power)
- **High Assay Low Enriched Uranium (HALEU)**: Enrichment to 5-20% U-235 for next-generation small modular reactors (SMRs) and microreactors
- **Enrichment as a Service**: Novel, scalable, cost-competitive enrichment technology to fill the critical gap in the US nuclear fuel cycle (conversion → enrichment → deconversion/fabrication)

## Market Standing
- **Valuation/Market Cap**: Not disclosed (private company)
- **Key Metric**: Currently hiring for 64+ roles across engineering, construction, legal, and operations; actively building enrichment capacity
- **Notable Investors/Partners**: Described as backed by “institutions” and “generational companies” – specific names not publicly available [generalmatter.com/careers](https://generalmatter.com/careers/)
- **Growth Signals**: Aggressive hiring across multiple disciplines; establishing a physical presence in Los Angeles (HQ) and Paducah, Kentucky (construction/manufacturing); addressing a critical national security gap (US currently performs <1% of global enrichment)
