General Matter is enriching uranium in America with a mission to design, build, and operate the world's lowest-cost nuclear fuel enrichment services in the United States. The company was incubated by Founders Fund and is backed by top-tier investors, applying first-principles engineering to restore America's nuclear fuel production capability.
As Materials & Process Engineer, you will be the materials generalist bridging chemistry and materials science with hardware development. You'll own how metals are selected, characterized, and qualified across General Matter's hardware, working at the interface of chemistry and hardware development alongside design, manufacturing, and test engineering teams.
Key responsibilities include:
**Materials & Process Development:**
- Own selection, characterization, and qualification of metallic materials across hardware
- Develop physical, mechanical, and thermal property data and design allowables to support hardware design decisions
- Define and improve manufacturing and special processes for metals (heat treatment, welding, etc.)
- Drive material and process choices that increase reliability and reduce cost as products move from development into production
**Cross-Functional Interface:**
- Serve as connective tissue between chemistry/materials-science and hardware development, translating materials constraints into engineering decisions
- Partner daily with design, manufacturing, and test engineering to solve complex materials and process challenges
- Provide technical review of drawings, specifications, and material requirements
**Characterization & Failure Analysis:**
- Lead root-cause investigations using fractography, metallography, and mechanical testing
- Establish characterization and inspection methods, including non-destructive evaluation, to control quality
- Build data, documentation, and standards that enable materials decisions to scale with the company
This is a hands-on engineering role focused on how materials behave in service under load, temperature, and demanding environments, and how to reliably get them into production. You'll work in a fast-paced, intense, Skunkworks-style environment.
**Requirements:**
- Bachelor's degree in materials engineering, metallurgical engineering, mechanical engineering, or related engineering discipline
- 5+ years of professional materials and/or process engineering experience
- Hands-on experience taking materials and processes from selection through characterization, qualification, and into production
- Working breadth across metallic materials
- Evidence of exceptional ability (prior projects, portfolio of work, completed products, etc.)
- Ability to obtain and maintain any required security clearance and access authorization
**Preferred:**
- Master's degree or Ph.D. in materials engineering or related field
- Genuine generalist depth across metals (heat treatment, welding, forming, casting/forging, coatings)
- Experience with failure analysis and characterization techniques (fractography, metallography, SEM, FTIR, mechanical testing)
- Experience serving as interface between chemistry/materials-science function and mechanical/hardware design and manufacturing teams
- Familiarity with material qualification, design allowables, and industry specifications (ASTM, ASME, AWS, NACE, etc.)
- Experience in fast-paced, resource-constrained startup or Skunkworks-style environment
