Job description

About the Company
General Matter is enriching uranium in America.
Our goal is to design, build, and operate the world's lowest-cost enrichment services in the United States.
Our mission is to restore America's ability to produce nuclear fuel-fuel that will power AI, advanced manufacturing, critical industries, and the next generation of nuclear reactors.
Ultimately, our work will help power national ambitions and enable a high-energy society.
We were incubated by Founders Fund, like Anduril and Palantir before us, and are backed by top-tier investors. 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 Mass Spectrometry Chemist at General Matter, you will play a critical role in establishing and advancing our analytical measurement capabilities for uranium isotopic analysis. You'll work hands-on with cutting-edge mass spectrometry instrumentation - including isotope-ratio mass spectrometry and ICP-MS systems - to develop, validate, and execute methods that directly support our enrichment operations and product certification. This is a rare opportunity to build measurement systems from the ground up at a next-generation nuclear facility during rapid commercial scale-up, where your technical work immediately impacts our ability to produce low-cost nuclear fuel at scale. If you seek high impact and are excited by fast-paced, intense, Skunkworks-style projects in service of a mission of national importance, we encourage you to apply to join our Chemistry team.
Responsibilities
  • Develop, optimize, and validate analytical methods for uranium isotopic analysis using mass spectrometry (isotope-ratio MS, ICP-MS)
  • Perform isotopic sampling, sample preparation, and measurement workflows to support enrichment process monitoring and product certification
  • Operate, maintain, calibrate, and troubleshoot mass spectrometry instrumentation to ensure measurement accuracy, precision, and reliability
  • Integrate measurement systems with sample-handling workflows and support automation and process improvements
  • Collaborate closely with the Chemistry team and cross-functional partners (Operations, Product Certification, Engineering) to define analytical requirements and deliver results that drive decision-making
  • Document methods, maintain rigorous QA/QC protocols, and support regulatory and compliance reporting as needed
  • Contribute to continuous improvement of analytical capabilities as General Matter scales production

Basic Qualifications
  • Bachelor's degree in Chemistry, Radiochemistry or a related field, or equivalent experience
  • Hands-on laboratory experience with mass spectrometry techniques (ICP-MS, isotope-ratio MS, or similar)
  • Demonstrated ability to develop, troubleshoot, and optimize analytical methods and instrumentation
  • Strong problem-solving skills and attention to detail in data collection, analysis, and documentation
  • Evidence of exceptional ability - prior research projects, published work, or demonstrated technical contributions in analytical chemistry or instrumentation
  • Ability to obtain and maintain required security clearance and access authorization for work with nuclear materials
  • Ability to work on-site in Los Angeles, CA or Paducah, KY

Preferred Skills and Experience
  • Experience with uranium isotopic analysis, nuclear materials characterization, or safeguards measurement techniques
  • Familiarity with TIMS, MC-ICP-MS, or other isotope-ratio mass spectrometry platforms
  • Prior work in a DOE national laboratory, NRC-licensed facility, nuclear fuel-cycle company, or instrumentation vendor environment
  • Experience in method validation, regulatory compliance (e.g., DOE, NRC, ISO standards), or quality assurance in analytical chemistry
  • Background in fast-paced, resource-constrained, or startup environments where autonomy and bias toward action are required
  • Strong communication skills and ability to collaborate across technical and operational teams

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